Tested positive for Lyme disease IgM but my western blot test came back negtive?

Tested positive for Lyme disease IgM but my western blot test came back negtive?

Then it's not Lyme: Lyme disease can be tricky -and you want to make sure you see someone like an Infectious Diseases doctor who knows how to treat it. The diagnosis is actually based on clinical findings, and the lab testing is generally 'supportive'. Since you're Western blot is negative, then it's very unlikely you have Lyme. There are other diseases that could cause 'Lyme-like' symptoms -and good to get evaluated ...Read more

What would cause a positive Lyme titer but negative western blot?

What would cause a positive Lyme titer but negative western blot?

see details: The lyme titer is nonspecific and can be positive by itself if the presence of other autoimmune diseases, viral infections or a history of lyme in the distant past. I negative western blot rules out active lyme disease. ...Read more

Ebv panel. Ebv nuc antigen igg=157, early ag igg=12.7, EBV VCA igg=112, EBV VCA igm=10.6. Please explain. Concerned about spleen. Symp=fatigue/fog?

Ebv panel. Ebv nuc antigen  igg=157, early ag igg=12.7, EBV VCA igg=112, EBV VCA igm=10.6.  Please explain.  Concerned about spleen. Symp=fatigue/fog?

? Active infection: It's impossible for me to answer with certainty since i don't know the normal ranges your lab uses. If early ag & vca igm are elevated above normal this indicates active ebv infection.I don't know if it is acute or chronic without knowing your history. If chronic i see that as a sign of poor immune function.Immune-boosting herbs/supplements & IV vit c drips may help, but find why immunity is poor. ...Read more

2009- ELISA HIV test- positive, western blot- neg. 2010-oraquick negative. 2014- elisa-indeterminate wb- neg. Low risk for hiv. Could I have lupus?

2009- ELISA HIV test- positive, western blot- neg. 2010-oraquick negative.  2014- elisa-indeterminate wb- neg. Low risk for hiv. Could I have lupus?

Not a test for lupus: The HIV test is not a test for lupus. What's clear is that you don't have hiv. You'll never know why your elisa was positive and then indeterminate, and it's not worth investigating. False positive elisas are not uncommon; that's why they have to be confirmed with western blot. ...Read more

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Makes perfect sense: Igm antibodies rise only during the actual, acute infection. They then fade away and are replaced by the various igg antibodies, which are the ones that provide lifetime protection against the same strain of the virus. So your numbers are consistent with the fact you had mono years ago. There is no igm, and positive igg levels. So you are immune and do not currently have mono. ...Read more

Lyme IgG test .91 is this high?

How about Ana screen positive, Ana titer (ifa) 1:80 Hi, and pattern speckled?

How about Ana screen positive, Ana titer (ifa) 1:80 Hi, and pattern speckled?

How about it?: Up to a quarter of women your age have an ANA (immunofluorescent antibody) at a low titer like yours with a speckled pattern. If there's a question of whether you have lupus or one of its relatives, it's a piece of information to note and file for future reference. A negative ANA would rule several things out. Your result proves nothing positive. Best wishes. ...Read more

My serum test is negative for endomysial antibody  iga, ttg tissue transglutasminase iga, gliadin antibody igg. But positive for gliadin  antibody iga?

Treat the person: Lab tests mean nothing in isolation, and have many false positives and false negatives. The decision to make a trial of a gluten-free diet will be between you and your gastroenterologist or dermatologist based on the big picture. ...Read more
