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
Radiation-free test: Elisa is a test that detects a foreign substance (antigen) or an antibody in blood. Elisa uses an enzyme bound to a 2nd antibody . In the final step the enzyme converts indicator material to a different color. The amount of color detected corresponds to the amount of antigen or antibody present. Elisa gives the same answer as rast without using radioactive radioisotopes. ...Read moreSee 1 more doctor answer
Tested false positive ELISA HIV test last month. Negative ifa and western blot and naat. 2 negative oraquick all 1 1/2 year post exposure. Hiv?
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
My friend test std, results . chlamydia trachomatis positive, abnormal andnon reactive negative. Hsv 2 igG. 2.69. HSV 1 igG. 37.90. the me?
What's the question?: You don't ask a question -- I'm not sure what information you're looking for. These HSV test results are positive for both HSV1 and HSV2. However, when the HSV1 IgG antibody test is very strongly positive and the HSV2 result is much lower, as in your friend, the HSV2 result sometimes is false. Additional testing, preferably with a Western blot test, can sort it out. ...Read moreSee 1 more doctor answer
Old or recent herpes infection? Herpes 6 ab panel blood results: herpes virus 6 igm neg:<1:10<1:10(my value) herpes virus 6 IgG pos<.99 mine 13.56
I don't get it: Herpes 6 is the roseola virus which infects nearly all of us since early childhood. There is speculation about some possible indirect relationship to multiple sclerosis. It is not an std! it is not the same as herpes simplex which is responsible for genital herpes or cold sores (hsv 2, hsv1). Why test for hsv6?. Acyclovir will yield no benefit for this unless you have a (rare) acute hh6 infe. ...Read more
Does the western blot trump the elisa? Tested positive via ELISA IgG for hsv2,but later tested negative via western blot. No symptoms. Do I have hsv2?
Western blot more: specific, ELISA more sensitive. One positive ELISA and one negative Western blot says that you do not have enough antibodies to HSV 2 for confirmation of diagnosis. It may be prudent to repeat the tests in 3-4 months to make sure that negative Western blot was not due to incomplete/early immune response. ...Read more
Is there any facility to confirm HSV 2 in india like glycoprotin test i got ELISA negtiv 2times and once IgG positiv please tell me laboratry name plz?
HSV 2: You cannot differentiate between hsv types 1 and 2 using antibody testing because of the high frequency of cross-reactivity. The only sure way to do this is to isolate the virus from active lesions and test the virus for serotypes. This is fairly sophisticated, but imagine most large medical schools in india may have a lab that can do this. ...Read more
False pos ELISA HIV tests, neg naat viral load test, neg western blot, ifa and oraquicks neg too. All 15 months post risk event. What should I do?
Be grateful, man!: You've been obsessing about this too long. Sit down and talk with your physician about fears. If you'll forgive my frankness, talk with him/her and some wise adults (maybe even dad) about your emerging sexuality and how you've explored. By your age, we've all made mistakes. Embrace being a man, decide how you want love to be for you, and cherish adult love while resolving to be safe ; kind. ...Read more

Without more info: and only the data you submitted in your question, I would put it together the way you did: the first Advia hepC Ab test was a false positive. I presume other experts who arranged your follow-up testing have suggested the same interpretation. Stay well:) ...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?
? 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
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 moreSee 1 more doctor answer
I have to take a ELISA test today for Lyme disease but i was just wondering how does ELISA test work?
Sandwich assay...yum: Elisa = enzyme-linked immuno sorbent assay. Done by adding serum from a subject to a plate w/antibody against the infection you're testing for on its surface. The antigen (or protein) from the infection binds to the antibody on the plate. Then another antibody to the infection w/color signal chemical attached is added on top and binds to the antigen. If infection is there color can be measured. ...Read more
Her2 positive: Breast cancer is broken into 4 types - each involves the presence or absence of estrogen, progesterone, and her 2 receptors: luminal a (er/pr positive, her 2 negative), luminal b (er/pr positive, her 2 positive), her 2 (er/pr negative, her 2 positive), triple-negative (er/pr negative, her 2 negative). Patients who are her 2 positive herceptin, (trastuzumab) a powerful drug that greatly improves survival. ...Read moreSee 2 more doctor answers
2 false pos ELISA HIV tests, all 1 1/2 years post exposure. Neg western blot, ifa, naat and 2 neg oraquick home tests. What is my HIV status? Help!
Likely negative: There is typically a "window" of 3-6 months after exposure where you could be HIV positive but test negative. Since you didn't get your testing until well after that, i'd say the confirmatory tests (western blot, ifa) are what you should go by. The elisa is very sensitive and can have false positives- that's why we rely on the confirmatory tests. I would consider your status to be negative. ...Read more

Anti-DNA antibodies: Simple blood tests can be performed to test for anti-dna antibodies. Usually the screen is started with a basic ANA test which can then be followed with more specific antibody testing to determine if a specific disease can be identified. Of course, symptoms must also correlate since we do not simply provide diagnosis based on lab findings. ...Read more
