The recommended testing to determine whether the patient has achieved an SVR is a quantitative HCV RNA level 12 weeks after completing therapy (Figure 4). [ 12, 13] An undetectable HCV RNA level 12 weeks after completing therapy is referred to as SVR12 and this generally translates into a long-term cure of HCV infection. [ 12, 14, 15] Some experts will obtain an HCV RNA level 24 weeks after completing treatment in selected patients, such as those with cirrhosis.
What does HCV-positive recipient mean?
Recipients of blood transfusions or solid organ transplants prior to July 1992, before better testing of blood donors became available health care workers after needle sticks involving HCV-positive blood recipients of blood or organs from a donor who tested HCV-positive
Do you need treatment if you are HCV positive?
Yes. Recent data reveal that up to approximately half of people who test anti-HCV positive do not have current chronic infection ( 1 ), indicating they may have experienced spontaneous clearance after acute infection. Only those with current infection as evidenced by a positive HCV RNA test need treatment.
How is sustained virologic response measured after HCV treatment?
Measurement of Sustained Virologic Response Following HCV Treatment This graphic shows common time points for measurement of HCV RNA levels after completion of therapy. The preferred measurement for evaluation of SVR is an HCV RNA level 12 weeks after completing therapy (SVR12). The SVR4 is often obtained in research trials.
What follow-up testing for hepatitis C virus (HCV) is indicated?
Follow-up testing for HCP exposed to blood or body fluids from a source who tests anti-HCV positive but HCV RNA negative is not currently recommended, as source persons with that laboratory result profile are not considered infectious.
Do you still test positive for hep C after treatment?
Other things to know: After a successful course of treatment for hepatitis C, the hepatitis C antibody remains detectable, but the hepatitis C RNA will be undetectable. If you plan to donate blood, you will be tested for the hepatitis C antibody and will be turned away even if you do not have an active infection.
What happens after treatment for hep C?
After you clear your hep C (being cured) you won't have any immunity to protect you from catching it again. You can lower your risk of catching hep C again by avoiding blood-to-blood contact with other people.
How often check HCV viral load after treatment?
Quantitative HCV viral load testing is recommended 12 or more weeks after completion of therapy to document sustained virologic response (SVR), which is consistent with cure of chronic HCV infection.

Hepatitis C virus (HCV) genotype 2a has a better virologic response to antiviral therapy than HCV genotype 1b - PMC. The . gov means it's official.
What are the chances of hep C coming back after treatment?
In fact, once you're considered cured, the average risk of recurrence is less than one percent. Although treatments are better, it's still possible to contract a new infection in the future. Whether you have a history of hep C or not, it's important to take precautions to prevent HCV.
How long does it take for your liver to heal after hep C treatment?
If someone's liver has mild to moderate damage (fibrosis) and the hepatitis C virus is eliminated and no other liver damage effects are occurring, the liver can regenerate and heal within a few days up to 3-6 months, approximately.
What is a normal HCV viral load?
The viral load results from the quantitative PCR test can range from 15 to 100,000,000 IU/L. If your results are: Fewer than 15 IU/mL: The virus is detected, but the amount can't be measured exactly. You may need to return later for another test to see if the measurement changes.
What is the normal range for HCV?

If the disease is caught early and treated, people with hepatitis C can live a normal life. Approximately 3 to 5 million people in the United States are living with chronic hepatitis C, an infection that causes inflammation and scarring in the liver.
When should I retest for hep C?
After 6 months , most people will have developed enough antibodies for an HCV test to detect. In rare cases, however, antibodies can take up to 9 months to develop. If a person has a test during this window period, a hepatitis C antibody test may return a negative result.
When is HCV treatment contraindicated?
Current absolute contraindications to combination therapy include a known hypersensitivity to pegylated interferon and/or ribavirin, autoimmune hepatitis, decompensated liver disease, pregnant women, men whose female partners are pregnant and patients with hemoglobinopathies.
Is chronic hep C curable?
Today, chronic HCV is usually curable with oral medications taken every day for two to six months. Still, about half of people with HCV don't know they're infected, mainly because they have no symptoms, which can take decades to appear.
What is the aseptic technique for HCV?
All health-care personnel, including those who are HCV positive, should follow a strict aseptic technique as described by the National Institute for Occupational Safety and Health and the CDC, including appropriate hand hygiene, use of protective barriers, and safe injection practices.
How rare is hepatitis C?
Now that more advanced screening tests for hepatitis C are used in blood banks, the risk of transmission to recipients of blood or blood products is considered extremely rare, at <1 case per 2 million units transfused.
How long does it take for antibodies to show up in a blood test?
The window period for acute HCV infection before the detection of antibodies averages 8 to 11 weeks, with a reported range of 2 weeks to 6 months.
What is the risk of cirrhosis in the following year?
Patients who develop cirrhosis have a 1%–4% annual risk of developing hepatocellular carcinoma and a 3%–6% annual risk of hepatic decompensation; for the latter patients, the risk of death in the following year is 15%–20% ( 7 ).
Can hepatitis C cause liver enzymes to fluctuate?
Yes. It is common for patients with chronic hepatitis C to have fluctuating liver enzyme levels, with periodic returns to normal or near normal levels. Liver enzyme levels can remain normal for over a year despite chronic liver disease ( 28 ).
Does dental surgery spread hepatitis C?
As long as Standard Precautions and other infection-control practices are consistently implemented, medical and dental procedures performed in the United States generally do not pose a risk for the spread of hepatitis C.
Is hepatitis C test complete?
If a person tests positive for HCV antibodies, hepatitis C testing is not considered complete unless the initial positive anti-HCV test is followed by a test for HCV RNA as per CDC guidelines. A positive test for HCV RNA is needed before a patient can be diagnosed with current HCV and begin receiving treatment.
What to do if you have hep C and you are not cured?
Your doctor will refer you to a liver specialist if you are not cured of your hep C. The specialist will advise on your other treatment options. These might involve using a different treatment drug or the same treatment but with added Ibavyr (ribavirin).
How long after treatment do you have to have a PCR test?
You need to have a PCR viral detection test 12 weeks after your treatment finishes to check if you are cured. It is VERY IMPORTANT to attend for this post-treatment check up. You can’t assume that treatment has cured your hep C. You can find out for sure with the final PCR test.
Can you catch hep C again?
Risk of catching hep C again. After you clear your hep C (being cured) you won’t have any immunity to protect you from catching it again. You can lower your risk of catching hep C again by avoiding blood-to-blood contact with other people.
Can hepatitis C be treated?
If treatment is not successful. Treatment does not always cure hepatitis C and is unsuccessful in five of every 100 cases. This can happen for many different reasons including your genetics, the virus mutating, or if you miss some pills during treatment. It is important to remember:
Can you have liver cancer if you have hep C?
Ongoing liver damage. If you are cured of hep C you might still have existing liver damage. You will still have a risk of liver cancer if you have cirrhosis, even after being cured of hep C.
How to treat HCV in cirrhosis?
One important step in treating HCV in persons with cirrhosis is to determine whether the cirrhosis is compensated or decompensated. [ 1, 2] The Child-Turcotte-Pugh score is an important component of determining the status of the cirrhosis and predicts morbidity and mortality. [ 3, 4] The treatment approach and goals are divergent based on the classification of compensated versus decompensated cirrhosis. In particular, HCV protease inhibitor-based regimens are not recommended for use in persons with decompensated cirrhosis due to the risk of hepatotoxicity with some medications and lack of data with the others. [ 5]
What is the goal of a sustained virologic response?
The most important immediate goal of treatment is to achieve a sustained virologic response (SVR), which is required before observing the subsequent benefit in liver-related and other outcomes. The next intermediate-term priority with therapy is to decrease the patient’s risk of developing hepatic decompensation.
What is the AASLD-IDSA HCV guidance?
The AASLD-IDSA HCV Guidance addresses this group of patients in the section Unique Patient Populations: Patients with Decompensated Cirrhosis. [ 5] The key recommendation the guidance is that general management and treatment of all patients with decompensated cirrhosis should be performed by a medical practitioner highly experienced in managing persons with chronic HCV infection and decompensated cirrhosis. Accordingly, referral of these patients to an expert, ideally at a transplant center, is strongly recommended. Patients with decompensated cirrhosis include patients who may or may not be a candidate for liver transplantation and may include patients with hepatocellular carcinoma.
What is considered a decompensated cirrhosis?
Definition of Decompensated Cirrhosis. Individuals with cirrhosis are considered to have decompensated cirrhosis if they score 7 or higher on the Child Pugh-Turcotte-Pugh score and/or develop any of the following complications: ascites, jaundice, variceal hemorrhage, or hepatic encephalopathy. [ 1, 2, 3]
What are the complications of hepatitis C?
Individuals with chronic hepatitis C virus (HCV) infection and cirrhosis have an increased risk of developing severe liver-related complications, including hepatic decompensation, hepatocellular cancer, and death. Accordingly, any person with chronic HCV infection who is diagnosed with compensated cirrhosis should be considered as ...
Does cirrhosis affect the response to therapy?
The impact of cirrhosis on the response to therapy has changed over time with evolving treatment regimens. The following summary of clinical trials involving persons with compensated cirrhosis illustrates a significant improvement in SVR rates among patients with cirrhosis with regimens that include direct-acting agents.
Is cirrhosis a decompensated disease?
Compensated Cirrhosis: In general, individuals with compensated cirrhosis have mild hepatic impairment (Child-Turcotte-Pugh class A) ( Figure 1) and generally do not have clinical manifestations of decompensated disease, specifically jaundice, ascites, variceal hemorrhage, or hepatic encephalopathy.
What is sustained virologic response?
A sustained virologic response is associated with a reduction in fibrosis (liver scarring). Stopping viral replication stops inflammation in the liver and permits liver cells to be renewed. Although sustained virologic response is agreed by liver experts to signify that hepatitis C virus (HCV) infection has been cured, ...
How long does it take for hepatitis C to cure?
Hepatitis C infection is cured if the virus is undetectable 12 weeks after the completion of a course of direct-acting antiviral treatment. This is known as a sustained virologic response (SVR). Cure rates are very high; around 97% of people who start a course of treatment are cured and viral rebound after completing treatment is very rare.
Does hepatitis C remain in the body after treatment?
Does hepatitis C virus remain in the body after successful treatment? Persistence of very low-level hepatitis C infection after a sustained virologic response to hepatitis C treatment is an extremely rare event and is not associated with any liver damage, Spanish researchers report in Nature Scientific Reports this week.
Does hepatitis C show up in serum?
Hepatitis C virus was not detected in serum samples at any visit, but the participant did test positive for HCV antigenomic strand at the second visit. At subsequent visits HCV antigenomic strand was not detected.
Is viral rebound rare?
Viral rebound after sustained vir ologic response is rare, but it is unclear how rare it is and whether persistence of low-level infection is associated with continuing liver damage . Furthermore, it is unclear if a compromised immune system – as in advanced HIV disease – might encourage low-level viral persistence.
Is viral persistence rare?
The investigators conclude that viral persistence after achieving sustained virologic response is a rare event, but evaluation of people who have achieved sustained virologic response using ultrasensitive tests may be warranted before organ and blood donation, and for women who wish to have children after being cured of hepatitis C .
How often should I check for HCV?
Note that screening for HCV infection is recommended at least once in a lifetime for all adults aged ≥18 years (except in settings where the prevalence of HCV infection is <0.1%; currently prevalence among US adults is estimated to be 1.0%). [ 34]
What is CDC guidance for laboratory testing and follow-up of health care personnel (HCP) who have been potentially
This guidance provides CDC recommendations for laboratory testing and follow-up of health care personnel (HCP) who have been potentially exposed to hepatitis C virus (HCV) through an exposure to blood or other infectious body fluid.
Can HCV be tested for other bloodborne pathogens?
However, baseline testing may be indicated for other bloodborne pathogens. In addition, HCP testing for HCV infection may be considered for other purposes, including medicolegal concerns, per institutional protocols, or obtaining HCV RNA testing when the source tested negative for anti-HCV under Option B but has ongoing exposures.
Is RNA a reliable test for HCV?
HCV RNA is the more reliable test to determine current HCV infection, particularly in cases when a source is known or suspected to have recent risks for HCV (for example, injection drug use within the past four months), or if risk cannot be reliably assessed. [ 3 ] .
Can you test for anti-HCV with reflex to RNA?
However, for any person who has signs or symptoms of viral hepatitis, or for those who wish absolute certain confirmation that transmission did not occur from the past exposure, a test for anti-HCV with reflex to RNA could be considered.
Can HCP be exposed to early HCV?
These data suggest the possibility that in some health care settings HCP may be exposed to source patients with early HCV infection prior to development of detectable HCV antibody.
What is hepatitis C?
Hepatitis is an inflammation (swelling or tenderness) of the liver. Hepatitis C virus (HCV) is the most common form of viral hepatitis and usually causes a chronic, long-term infection lasting months or years before diagnosis. About 3.5 million people in the U.S. have chronic HCV. Symptoms of HCV are often like the flu and not too harsh.
How does hepatitis C spread?
HCV is spread through a carrier, which is someone who has the virus in his or her blood. A carrier may or may not have symptoms of HCV. Since the virus is in the blood, it can spread through exposure to blood or, rarely, bodily fluids of a carrier. This can happen through:
What are the symptoms of HCV?
Many cases of HCV are not found because there are no symptoms, or the symptoms are vague and may seem like the flu. Symptoms may start from two weeks to six months after exposure, though the average is six to seven weeks.
Treatment for HCV
The purpose of HCV care is to prevent the development of cirrhosis, complications from cirrhosis, need for liver transplantation, liver cancer and early death. There is no vaccine to prevent HCV but treatment options are available.
Living with HCV
Check in with your health care provider as needed, such as when you start a new medication.
Mixed Genotypes
Rarely, genotyping assays may indicate the presence of a mixed infection (eg, genotypes 1a and 2). Treatment data for mixed genotypes with DAAs are sparse but utilization of a pangenotypic regimen should be considered. When the correct combination or treatment duration is unclear, expert consultation should be sought.
Drug-Drug Interactions Between DAAs and Calcineurin Inhibitors
The interactions of DAA agents and calcineurin inhibitors are complex and unpredictable without formal studies of drug-drug interactions. A summary of drug-drug interactions between calcineurin inhibitors and DAAs with recommended dosing is provided in the table below.
What percent of Americans have HCV?
Genotype 1 is the most common in the United States, affecting about 75 percent of Americans with HCV. Genotype 2 is the second most common, affecting 20 to 25 percent of Americans with HCV.
What is SVR in hepatitis C?
What is SVR? The goal of hepatitis C therapy is to clear your blood of the hepatitis C virus (HCV). During treatment, your doctor will monitor the level of virus in your blood ( viral load ). When the virus can no longer be detected, it’s called a virologic response, which means your treatment is working.
How many genotypes are there for hepatitis C?
Hepatitis C medications are often classified by the genotype of the virus that they are designed to treat. A genotype is a specific genetic strain of the virus that is created as the virus evolves. There are currently seven known HCV genotypes, plus more than 67. Trusted Source.
How long do you take a drug to cure a virus?
They usually take the medications for 12 to 24 weeks, or longer.
When did Technivie stop being used?
These include the drug Olysio (simeprevir), discontinued in May 2018, and the drugs Technivie (ombitasvir/paritaprevir/ritonavir) and Viekira Pak (ombitasvir/paritaprevir/ritonavir plus dasabuvir), which were discontinued on January 1, 2019. All DAAs are combinations of drugs. Scientists have discovered that combining drugs ...
Can you be reinfected after SVR?
Your blood will forever contain hepatitis C antibodies. That doesn’t mean you can’t be reinfected. You should still take preventive measures to avoid exposure to the many strains of HCV.
Treatment
- The treatment of hepatitis C should include a pretreatment baseline evaluation, consideration of drug interactions, evaluation of treatment response during and after therapy, and monitoring for safety during treatment. A typical schedule for clinic visits related to an 8- or 12-week treatment …
Introduction
- Figure 1. HCV RNA Assay Reports The optimal and standard approach to monitoring for treatment efficacy consists of repeated measurement of quantitative HCV RNA levels. Monitoring requires use of a highly sensitive quantitative HCV RNA assay, typically with a lower limit of quantification in the range of 12 to 25 IU/ml.[1] In addition, to minimize interassay and interlaboratory variation…
Diagnosis
- Figure 3. Measurement of Sustained Virologic Response Following HCV Treatment The recommended testing to determine whether the patient has achieved an SVR is a quantitative HCV RNA level 12 weeks after completing therapy (Figure 3).[11,12] An undetectable HCV RNA level 12 weeks after completing therapy is referred to as SVR12 and this generally translates int…
Adverse effects
- On October 22, 2015 the US FDA issued a Drug Safety Warning that treatment with ombitasvir-paritaprevir-ritonavir, with or without dasabuvir, can cause serious liver injury, mostly in patients with underlying advanced liver disease.[16] In most of the reported cases, the liver injury occurred within 1 to 4 weeks of starting treatment. Elevations in ALT to greater than 5 times the upper lim…
Clinical significance
- Hepatitis B (HBV) reactivation associated with severe hepatitis flare has been increasingly recognized as a potential adverse event associated with HCV DAA therapy. Previous reports have described HBV reactivation after interferon-based therapy, but in these prior cases, clinically significant hepatitis was rare. Chronic HCV has been known to suppress HBV replication in pers…
Risks
- The AASLD-IDSA HCV Guidance provides specific recommendations that address the risk of HBV reactivation following initiation of treatment for HCV.[7] The following summarizes these AASLD-IDSA HCV Guidance recommendations.
Preparation
- We recommend obtaining baseline HBsAg, anti-HB core, and anti-HBs prior to starting HCV DAA therapy to evaluate for risk of HBV reactivation during DAA therapy for HCV. Individuals with a positive baseline HBsAg should have a baseline HBV DNA level ordered. Based on results from this baseline evaluation, we recommend the following:
Assessment
- The approach to monitoring patients following completion of a course of HCV therapy depends entirely on the patient's response to therapy. Three main scenarios exist: (1) the patient achieved an SVR12, (2) the patient completed therapy but did not achieve an SVR12, or (3) the patient had an inadequate treatment course because of adherence problems, intolerance, or laboratory toxic…
Contraindications
- The AASLD-IDSA guidance recommends the following for patients who did not achieve an SVR with HCV therapy:[7]
