This test works by producing a color change in a solution when your sample is examined in the lab. The color change occurs as the result of a chemical reaction described as an enzyme-antibody reaction. vitapix / Getty Images.

Why do you need an EIA test?

You may need to have an EIA test if you develop symptoms or have had an exposure to certain infections. This test is also used to help in the diagnosis of allergies and some autoimmune conditions. An EIA test can also be used for identifying certain medications and for drug screening.

What is an EIA test?

An enzyme immunoassay (EIA) or an enzyme-linked immunosorbent assay (ELISA) is a blood or urine analysis that can help in the diagnosis of many infections and inflammatory conditions. This is a simple test that does not cause side effects. Your EIA can help in diagnosing the cause of your symptoms and is used to guide your therapy.

How much does an EIA blood test cost?

An EIA blood test costs between $50 and $200. Keep in mind that this cost may be higher if you are having tests for multiple allergens. An EIA urine test costs between $20 and $40.

What bacteria can be detected by EIA?

Lyme disease Borrelia burgdorferi bacteria. Syphilis Treponema pallidum bacteria. Other substances that can be detected by an EIA test include: Cancer markers: Cancer markers are proteins or hormones made by some types of cancer and they may be detected before cancer is large enough to be seen on imaging tests.

Where is blood collected for EIA?

For an EIA, your blood will usually be collected from a vein in your antecubital area (the inside of your arm at the level of your elbow), or from a vein in your hand.

How to prevent iatrogenic spread?

To prevent iatrogenic spread, never reuse needles, syringes or IV sets, use only new, clean needles with injectable medicines and use only licensed and approved blood products.

How often should you test equid?

USDA recommends testing every equid annually. There is no vaccine approved for use in the U.S.

Is EIA a threat to human health?

EIA is found widely throughout the world. There is no evidence that EIA is a threat to human health. EIA is a reportable animal disease in all states.

Can EIA be treated?

There is no treatment for EIA. Because infected animals become lifelong carriers they must be permanently isolated and quarantined or euthanized.

Is EIA a disease?

Equine Infectious Anemia (EIA) is a viral disease affecting only members of the equidae family (horses, ponies, zebras, mules, and donkeys). There is no vaccine or treatment for the disease. Infection is often in-apparent and results in a lifelong carrier state if the horse survives the acute phase of the infection. EIA is found widely throughout the world. There is no evidence that EIA is a threat to human health. EIA is a reportable animal disease in all states.

How has EIA disease been reduced?

Today, the wide availability of the EIA tests, laws and regulations that control movement of equids, and universal precautions taken to avoid spreading contaminated blood to other horses have reduced EIA disease incidence to a manageable level. Horse population losses in the United States dropped from thousands a year in 1975 to negligible losses today. Many recent outbreaks have been traced to transmission by man, especially where needles have been reused. These recent outbreaks remind us to adhere to universal precautions to reduce the role of man in transferring blood-borne pathogens in horses.

What is EIA in equine?

By Tim Cordes, DVM & Charles Issel, DVM, Ph.D. Equine infectious anemia (EIA) is a potentially fatal blood-borne infectious viral disease that produces a persistent infection among equids nearly worldwide. Although the disease has been recognized for centuries, its prevalence began to rise in the 1930s and reached its destructive peak in ...

How does EIA spread?

Investigation into these cases indicates virus spread by iatrogenic means such as re-use of needles, syringes, intravenous administration sets, and surgical equipment that is contaminated with infected blood from a positive horse. Other sources of infection identified in these cases include unsterilized lip tattooing equipment, blood contamination of multi-use vials of medication or vaccine, and transfusion of blood or blood products from untested horses or from foreign countries.

What are the most common vectors for EIA?

The most common vectors for spreading EIA are biting flies, or tabanids, particularly horseflies.

How long does it take to get an EIA test?

More recently, enzyme-linked immunosorbent assays (ELISA tests) reduced the time for a lab result from at least 24 hours to less than one hour. These serologic (blood) tests can confirm the diagnosis of EIA. Only USDA-approved laboratories can perform the EIA test in the United States. Accurate tests allow us to identify and remove positive reactors from herds and stop the spread of EIA among tested populations.

How do you know if a horse has EIA?

horse population today. There is no vaccine or treatment for the disease, and it is often difficult to differentiate EIA from other fever-producing diseases, including anthrax, influenza, and equine encephalitis.

When did EIA start?

Although the disease has been recognized for centuries, its prevalence began to rise in the 1930s and reached its destructive peak in the United States between the ’60s and ’70s. In 1975, 10,371 cases of EIA infection were detected in the United States; many of these cases exhibited severe clinical signs, and some resulted in death.

What is the treatment for EIA?

There is no specific treatment available for EIA nor is there a vaccine. Symptomatic and supportive treatments for fever, anemia and weight loss are applied on welfare grounds, at least until a positive diagnosis and the decision for euthanasia are made. Control is based on blood testing to detect infected horses and carriers and euthanasia or strict isolation of these individuals in insect-secure stables. Preventive measures for high-risk situations include the use of insect repellents and insect-secure stabling during times of the day when insects are most active. Veterinarians must use single-use disposable needles and syringes and strict disinfection of all instruments and equipment, that might become contaminated with blood, between animals.

How to diagnose EIA in horses?

The internationally-recognized blood test is called the Coggins test , after the virologist who first developed it. This test involves an agar gel immunodiffusion reaction and detects antibodies produced by the horse after infection with the EIA virus. A positive result indicates previous or current infection with the EIA virus. An exception ('false Coggins positive') occurs where a young foal has been born uninfected (see above) but acquires antibodies from its infected mother, via her colostrum. These foals (if not subsequently infected by infected milk) will usually become 'Coggins negative' by six months of age. A false negative result can occur if an infected horse is tested too soon after first infection i.e., before the horse has had time to react immunologically and produce antibodies to the virus.

What does it mean when a foal is positive for EIA?

A positive result indicates previous or current infection with the EIA virus. An exception ('false Coggins positive') occurs where a young foal has been born uninfected (see above) but acquires antibodies from its infected mother, via her colostrum.

What is the alternative to the Coggins test?

An alternative to the Coggins test is the C-ELISA test . There is also a test for virus particles in infected tissue but this is most useful if a horse has died after a short period of time and before a Coggins test will give a positive result. Other tests for detecting antibodies in the blood are available but are not as reliable, practical or universally-recognized as the Coggins test.

Can horses transmit EIA?

This means that the horse is a persistent viremic carrier and can potentially transmit the infection to other horses. The virus titer (blood antibody level) is higher in horses with clinical signs and the risk of transmission is higher from these animals than from carriers with a lower virus titer.

How to treat EIA?

After controlling the patient's underlying and contributing factors (eg, respiratory infection, allergy, allergic asthma), a combination of drugs can be used to prevent EIA. [ 1] The basis of treatment is with preexercise short-acting β 2 -agonist administration. [ 1] A role also exists for long-acting β 2 -agonists and mast cell stabilizers. Antileukotriene drugs have been shown to be effective as well (see Medications). [ 8, 9]

What is the treatment for an athlete who is experiencing an acute attack of EIA?

Treatment of the athlete who is experiencing an acute attack of EIA is the same as in any asthma attack situation and includes immediately removing the patient from competition or play.

How to maximize exercise performance with regard to bronchospasm?

The coordination and timing of competition with medication use can also maximize exercise performance with regard to bronchospasm. To minimize the likelihood of bronchospasms, the athlete can time the warm-up so that the competition coincides with a refractory phase (see Phases of EIA above).

How to help athletes with bronchospasm?

Sports selection can be helpful in guiding an athlete toward the performance of sports in environments that are less likely to cause bronchospasm. In addition, if the athlete has a choice, he or she can choose a time or place to exercise where the air is warmer and the humidity is higher. Likewise, a flexible athlete can change sports to be more active in these sorts of environments (eg, changing from running to swimming automatically increases the humidity of the environment). As indicated in Pathophysiology above, focusing on sports with less prolonged aerobic demands (eg, sprinting, weight lifting, baseball, football) is better tolerated by affected athletes.

Is consultation needed for EIA?

On the playing field, consultation is rarely available and is not needed in the acute EIA attack; however, access to the emergency medical system should be readily available.

Can an EIA attack be fatal?

The severity of an EIA attack varies greatly. Although cases of respiratory arrest and even death have been reported, the usual scenario is of a mild respiratory difficulty during play, which either spontaneously resolves or immediately responds to inhaled albuterol. Oftentimes, the athlete self-medicates and never leaves play or alerts the trainer or doctor.

What causes EIA?

EIA is caused by a retro virus and transmitted by horseflies. However, the infection can also be spread through blood-contaminated items such as unsterilized needles, syringes, etc.

Is there a cure for EIA?

There is no treatment or vaccine available in the U.S. at this time for EIA, though most horses that survive the acute form of this disease may have flare-ups from the symptoms episodically. Interestingly enough, there have even been studies done relating the human HIV virus and EIA, as they are both retroviruses.

Is EIA a disease?

EIA has become endemic in certain parts of the world, but is very uncommon in the United States. In fact, EIA is a reportable disease in the U.S., which means that if it is diagnosed in a horse in this country, the veterinarian is required to notify the USDA. There is no cure for Equine Infectious Anemia. It is spread by the horsefly.

What is EIA used for?

One powerful use of EIA is immunostaining, in which antibody-enzyme conjugates enhance microscopy. Immunohistochemistry (IHC) is used for examining whole tissues. As seen in Figure 2, a section of tissue can be stained to visualize the various cell types.

How sensitive is an ELISA?

ELISAs are extremely sensitive, allowing antigen to be quantified in the nanogram (10 –9 g) per mL range. Figure 3. Click for a larger image. (a) In a sandwich ELISA, a primary antibody is used to first capture an antigen with the primary antibody.

How to use sandwich ELISA?

In a sandwich ELISA, the goal is to use antibodies to precisely quantify specific antigen present in a solution, such as antigen from a pathogen, a serum protein, or a hormone from the blood or urine to list just a few examples. The first step of a sandwich ELISA is to add the primary antibody to all the wells of a microtiter plate (Figure 3). The antibody sticks to the plastic by hydrophobic interactions. After an appropriate incubation time, any unbound antibody is washed away. Comparable washes are used between each of the subsequent steps to ensure that only specifically bound molecules remain attached to the plate. A blocking protein is then added (e.g., albumin or the milk protein casein) to bind the remaining nonspecific protein-binding sites in the well. Some of the wells will receive known amounts of antigen to allow the construction of a standard curve, and unknown antigen solutions are added to the other wells. The primary antibody captures the antigen and, following a wash, the secondary antibody is added, which is a polyclonal antibody that is conjugated to an enzyme. After a final wash, a colorless substrate (chromogen) is added, and the enzyme converts it into a colored end product. The color intensity of the sample caused by the end product is measured with a spectrophotometer. The amount of color produced (measured as absorbance) is directly proportional to the amount of enzyme, which in turn is directly proportional to the captured antigen. ELISAs are extremely sensitive, allowing antigen to be quantified in the nanogram (10 –9 g) per mL range.

Where are antigens immobilized in ELISA?

In the direct ELISA, antigens are immobilized in the well of a microtiter plate. An antibody that is specific for a particular antigen and is conjugated to an enzyme is added to each well. If the antigen is present, then the antibody will bind.

Why are western blots not used for HIV screening?

Similar to the indirect ELISA, an indeterminant western blot can occur because of cross-reactivity or previous viral infections, vaccinations, or autoimmune diseases.

Can HIV be diagnosed by ELISA?

Thus, we cannot definitively diagnose an HIV infection (or any other type of infection) based on a single indirect ELISA assay. We must confirm any suspected positive test, which is most often done using either an immunoblot that actually identifies the presence of specific peptides from the pathogen or a test to identify the nucleic acids associated with the pathogen, such as reverse transcriptase PCR (RT-PCR) or a nucleic acid antigen test.
