Equivocal Lyme Test

There is a two-step process recommended by the CDC to test for Lyme. Patients with clinical history signs or symptoms suggestive of Lyme disease should be retested in 2 to 4 weeks in the event that the initial test result is negative.

Thats needed to come to any conclusion. With but am I grasping at this 91. It is possible for this test to produce a positive result for Lyme disease before blood tests turn positive but the evidence for the effectiveness of this test is poor and lumbar punctures come with their own risks.

Its really hard to get a Lyme Disease diagnosis so those of us lucky enough to get a positive or equivocal on the first stage test should jump at the opportunity for the 2nd test. General Information What causes Lyme disease. An immunoblot identifies the specific proteins to which the patients antibodies bind.

Cornells Lyme Multiplex assay provides a unique tool to determine the stage of Lyme disease infection treatment outcomes and vaccination status in dogs and horses. IF there is a change in the results that will make it a postive result for lyme. An immunoblot assay is used to supplement positive or equivocal Lyme EIA.

This was done in a BC lab. A negative result is equal to or less than 090. If there is a strong suspicion of Lyme as with your symptoms and the maybe yesmaybe no then an experienced Lyme doc would not wait around to see what bad thing happens next.

Polymerase chain reaction PCR testing detects the genetic material DNA of the Lyme disease. The ELISA test checks for antibodies proteins made by the immune system to fight infection made when the bodys immune system responds to the bacteria that cause Lyme disease. This fully quantitative test is only available at Cornell University through the NYS Veterinary Diagnostic Laboratory.

The ELISA test is designed to be very sensitive which means that almost everyone with Lyme. Positive or equivocal screening test results should not be interpreted as truly positive until verified as such using a supplemental assay eg B. Although there are no proteins that specifically diagnose B burgdorferi infection the number of proteins recognized in.

Ok my doctor just called me to tell me that I had an Equivocal test result from the Lyme Disease test. I know the tests can be negative and clinically you can be diagnosed and treated by LLMD which I am trying to get an appt. The screening test andor blot for B.

The process tests your blood for evidence of antibodies your body produces to resist spirochete bacteria which causes Lyme. An EIA is then used to confirm the presence of antibodies to Borrelia. An equivocal result is between 091 and 109.

The test that was equivocal is basically worthless. Lyme disease or where early Lyme disease is suspected but with negative test results should be retested in 2 to 4 weeks. The imprecision inherent in any method implies a lower degree of confidence in the interpretation of specimens with absorbance values very close to.

It is now one of the fastest growing infectious diseases in the US. Negative 109Is above or equi 1 doctor answer 1 doctor weighed in How accurate is a LYME DISEASE AB WREFL TO BLOT IGG IGM Test. My results cme back 91 which was said to be equivocal and athat all equivocal or positive should be checked by Western Blot.

Lyme ELISA Test The Lyme ELISA test is always performed first in the two-tiered Lyme disease testing sequence and the results determine the next step. But the test for Lyme said it has a normal range of 0-9. Patients in the early stages of Lyme disease and those who have been treated with antibiotics may not exhibit detectable antibody titers.

Aug 15 2005. In patients with long term symptoms a negative ELISA test usually excludes Lyme disease as a cause of these symptoms. Equivocal in an ELISA test.

If your doctor offers to do the second stage test definitely take them up on it. Lyme disease is the most common vector-borne disease in the Northern Hemisphere. Lyme disease is caused by infection with the Borrelia burgdorferi bacteria and is primarily transmitted to humans as well as dogs horses and other domesticated animals by the bite of infected ticks.

Polymerase chain reaction PCR test. A lot of people dont even get a positive or equivocal the first time around. Your doc didnt get much guidance from the equivocal test result but in my experience as a Lyme patient an experienced Lyme doc will not just wait to see what happens next.

Many with Lyme show up as that. A Lyme disease test detects antibodies to the Lyme disease bacteria Borrelia burgdorferi in the blood. The reference ranges for the Lyme ELISA test results are as follows.

Do you have a copy of the Western Blot showing the specific bands. If youve been bitten by a tick its normal to feel nervous that you might have contracted Lyme disease.
