What is the most accurate test for Lyme disease?
Testing for Toxins
- Hair samples: This is the least reliable method of testing for heavy metals.
- Blood test: It’s valuable only for testing acute exposure.
- 24-hour urine after DMSA: This is the most accurate assessment. Urine is collected for 24 hours after use of 100 mg of DMSA (Dimercaptosuccinic acid, a chelation medication) to pull ...
How long to get Lyme's disease test results back?
If you suspect that you may have Lyme disease there are two options for blood tests available through your G.P. The results of these tests can take from 7 working days to 4 weeks to come back.
How accurate are blood tests for Lyme disease?
than 99%, and specificity (the probability of not having the disease given a negative test) of greater than 99.5%. However high accuracy is not always the case and for Lyme disease the sensitivity of tests is poor as demonstrated in recently published papers. Lyme disease (Lyme borreliosis) is generally caused by the bite of a tick infected ...
Can you have Lyme with a negative Lyme test?
When an individual manifests symptoms consistent with Lyme disease and has been exposed to a tick endemic region, clinicians should consider a Lyme disease diagnosis, even with a negative test result.
How do you test for Lyme disease after treatment?
These tests are most reliable a few weeks after an infection, after your body has had time to develop antibodies. They include: Enzyme-linked immunosorbent assay (ELISA) test. The test used most often to detect Lyme disease, ELISA detects antibodies to B.
How long does IgG stay positive in Lyme?
IgM or IgG antibody responses to B. burgdorferi may persist for 10-20 years, but these responses are not indicative of active infection.
What does a positive IgG band 41 mean?
Two types of antibodies are detected in the Western blot test. This particular marker is called 41 KD (IGG) Band and hence is a IgG antibody marker. IgG antibodies are a sign of an older infection. In contrast, IgM antibodies reflect a relatively recent infection.
What is normal range for Lyme disease?
Reference Range Borrelia burgdorferi antibody enzyme immunoassay (Lyme index value) : < 0.9 = negative. 0.91-1.09 = equivocal. >1.1 = positive.
How do I know if my Lyme disease is gone?
As with many infectious diseases, there is no test that can “prove” cure. Tests for Lyme disease detect antibodies produced by the human immune system to fight off the bacteria (Borrelia burgdorferi) that cause Lyme disease. These antibodies can persist long after the infection is gone.
At what stages of Lyme disease are the IgG and IgM antibodies elevated?
Types of Lyme Disease Tests IgM antibodies usually peak within a few weeks after an infection with Borrelia bacteria and start to collapse 4-6 months after infection. IgG antibodies are slower to develop, beginning to show 4-6 weeks after exposure and may peak 4-6 months after exposure.
What does a positive IgG band 58 mean?
Optimal Result: 0 - 0.001 Units. Two types of antibodies are detected in the Western blot test. This particular marker is called 58 KD (IGG) Band and hence is a IgG antibody marker. IgG antibodies are a sign of an older infection.
What is band 23 Lyme?
This particular marker is called 23 KD (IGM) and hence is a IgM antibody marker. IgM antibodies reflect a relatively recent infection. IgG antibodies in contrast are a sign of an older infection. IgM antibodies usually disappear after eight weeks post-exposure.
Is band 93 Lyme specific?
Some Lyme specialists and scientists believe that there are five very specific bands on the Western blot test that are highly indicative of Lyme disease: band numbers 23, 31, 34, 39 and 93. If any of these bands are positive and the patient is experiencing symptoms of Lyme disease, they may feel treatment is warranted.
What is a positive Lyme test result?
A positive test only indicates that a person has most likely been infected with the agent of Lyme disease in the past or quite recently. The immune response has a long memory; therefore positive tests results may last for many years after the infection is gone.
What is a high number for Lyme disease?
It's important to emphasize that 476,000 is the estimated number of people treated for Lyme disease and likely includes some patients who were not actually infected. Q: CDC also states that approximately 35,000 cases of Lyme disease are reported each year.
What does positive Lyme IgM mean?
IgM antibodies are larger than IgG antibodies and when present in high numbers, may indicate a recent or new active infection. In short, a positive IgM may be a sign of a current, or very recent, infection.
What does a positive IgG Lyme test mean?
In short, a positive IgM may be a sign of a current, or very recent, infection. The IgG antibodies are produced once an infection has been going on for a while, and may even be present after the infection has been resolved.
Do you need to retest for Lyme disease after treatment?
No. The tests for Lyme disease detect antibodies made by the immune system to fight off the bacteria, Borrelia burgdorferi. Your immune system continues to make the antibodies for months or years after the infection is gone.
What causes false positive IgM Lyme?
False-positives, on the other hand, most likely result when your body is fighting off another infection, because the Lyme blood tests also detect the presence of antibodies to other bacteria or viruses. Illnesses such as syphilis and HIV, or even mononucleosis, is cause to question a positive test result.
What does a positive Lyme antibody test mean?
A positive ELISA result is abnormal. This means antibodies were seen in your blood sample. But, this does not confirm a diagnosis of Lyme disease. A positive ELISA result must be followed up with a Western blot test. Only a positive Western blot test can confirm the diagnosis of Lyme disease.
What does a barcode on a lyme test mean?
Your test result will look similar to a barcode, with bars in some bands and not in others. The location of the darker bars in your test result determines whether you likely have Lyme disease. Bars in the numbered bands linked to Lyme disease means you may have Lyme disease.
How long does it take for a lyme disease to show up?

How to diagnose lyme disease?
1. Go over your test results with your doctor. If your doctor orders a Western blot test, they'll contact you when they receive your results. Your doctor will interpret the results and decide whether to diagnose you with Lyme. However, you may want to be able to read and understand the results on your own.
How long after a tick bite can you feel symptoms?
Keep a journal to monitor long-term symptoms. You may not be symptomatic in the days or weeks immediately after a tick bite. However, symptoms such as fatigue, joint and muscle aches and pains, or digestive symptoms, may appear months later. Long-term symptoms also may persist even after treatment.
What is the first step in a lyme test?
The first step is to run a Lyme antibody blood test, which measure two types of antibodies against Lyme disease (immunoglobulin G or IgG and immunoglobulin M or IgM). If this test is positive, then a second test called a Lyme Western Blot should be run to confirm the results of the first test. The Lyme Western Blot looks at a series ...
Why is lyme disease testing controversial?
The methodology behind Lyme disease testing has long been a point of controversy among treating practitioners and part of this is due to differences in the laboratories themselves. The test kits that each lab uses vary and this may alter the sensitivity of the testing itself.

The Lyme Western Blot looks at a series of specific antibodies against the Lyme organism for both IgG and IgM. If someone has at least 5 out of 10 antibodies for IgG or 2 out of 3 antibodies for IgM, then the Lyme Western Blot is considered positive. The CDC does not recommend doing a Lyme Western Blot IgM test on anyone whose illness occurred ...
Does Lyme disease cause antibodies?
While in theory that sounds good, the reality is that many people who end with chronic Lyme disease may not have a healthy immune system to start with and therefore, do not produce antibodies in the amount needed to get rid of the infection or be picked up on a blood test.
Can you get a Western Blot if you have lyme disease?
To make matters even worse, since the CDC guidelines do not recommend doing a Lyme Western Blot if the Lyme screen is negative, your doctor may easily skip over the more sensitive and specific test that might help show if you have been exposed to Lyme disease.
Does Lyme disease get picked up on the Western Blot?
For example, we now know that many cases of Lyme disease on the West Coast of the United States is caused by Borrellia miyomotoi, which does not get picked up on the Lyme Western Blot. So it is possible that some patients who experience Lyme disease symptoms and have a negative test, may actually have a different strain ...
Do antibodies go down after treatment?
It can be maddening, as a patient as you would expect that antibody levels would go down once treatment had begun. However, this does not usually occur and each antibody can increase, decrease or go away completely with each test for reasons that are not well understood.
How to test for lyme disease?
CDC currently recommends a two-step testing process for Lyme disease. Both steps are required and can be done using the same blood sample. If this first step is negative, no further testing is recommended. If the first step is positive or indeterminate (sometimes called “equivocal”), the second step should be performed. The overall result is positive only when the first test is positive (or equivocal) and the second test is positive (or for some tests equivocal).
How long does it take for Lyme disease to develop?
Most Lyme disease tests are designed to detect antibodies made by the body in response to infection. Antibodies can take several weeks to develop, so patients may test negative if infected only recently.
What does CDC do?
CDC supports the development of new tests. New tests may be developed as alternatives to one or both steps of the two-step process. Before CDC will recommend new tests, they must be cleared by the Food and Drug Administration (FDA).
When is the second step positive?
If the first step is positive or indeterminate (sometimes called “equivocal”), the second step should be performed. The overall result is positive only when the first test is positive (or equivocal) and the second test is positive (or for some tests equivocal).

Does lyme disease raise C3A?
In one study, all early Lyme disease patients had higher C3a and C4a levels than the control group. [i] In another study, patients with chronic Lyme disease (and also patients with AIDS) had normal C3a levels but significantly elevated C4a levels.
Does C4A decrease with antibiotics?
And response to antibiotic therapy resulted in a significant decrease in C4a levels, where lack of response was associated with an increase in those levels. [ii] This test is not specific to Lyme disease, but at least it is a decent measure of systemic inflammation.
Is Lyme disease gone out of your system?
There is another test that can give us an idea whether the Lyme disease is actually gone out of our systems. This is an inflammatory marker, so it tells us whether there is continued inflammation (presumably caused by the Lyme bacterium) or whether that inflammation is no longer present.
Why is a Western Blot negative?
So a negative or less reactive elispot, immunoblot, or western blot could be due to large numbers of germs suppressing the immune system. Another issue is that Lyme and Bartonella live in persister forms and biofilms where the immune system cannot see them. Additionally, Lyme can hide in tissues with poor blood flow.
What is the test called for a lyme disease?
This is one type of immune reactivity test. The other type of immune reactivity test is called a western blot and the newer immunoblot. These tests see if your immune system is making antibodies against Lyme or one of the coinfections.

There is a current trend among some Lyme Literate Medical Doctors (LLMDs) to retest patients. The elispot tests through Armin Labs, Infectolab, and even IGenex measure if a type of white blood cell called a T Cell has reacted to Lyme or one of the coinfections. This is one type of immune reactivity test. The other type of immune reactivity test is ...
What does it mean when a person has a higher germ load?
Some physicians wrongly believe that a more reactive elispot, western blot, or immunoblot means the germs are more active or that a person has a higher germ load. The opposite of this is the belief that a non-reactive immune system test means the germ must be under control or out of the body.
Can you tell if you have recovered from lyme disease?
The truth is, there are no biologic markers or immune system tests that show if you have recovered or are recovering from Lyme and coinfections. Repeating elispot tests like those offered by Armin Labs, or western blot tests and immunoblot tests offered by IGenex (or other labs) do not have any scientific proof to show they can predict the end ...
Can lyme disease hide in blood?
Additionally, Lyme can hide in tissues with poor blood flow. So these germs can hide from immune cells, creating a falsely low immune response test. Also, the elispot test offered by Armin and others will not find Lyme or other germs when present up to fifteen percent of the time.
