How reliable are my negative results after 8 days? Hiv1 DNA PCR and elisa.

Too soon: Not reliable at all. I am shocked anyone would even offer you such a test before the test could possibly be valid! the HIV pcr test can be accurate after fourteen days. Most of us wait till day 21 after exposure to erase all doubts. You tested too soon! ...Read more

How do you measure anti-dna antibody? Using elisa?

How do you measure anti-dna antibody? Using elisa?

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

It's 1.10 years since my last risk. I tested HIV -ve in ELISA, WestBlot, p24, HIV Proviral-DNA PCR.Now, i got small lump in left armpit. should i test?

I'm not worried: A single guy with a social life does well to get checked for HIV yearly just as a courtesy to those who he may date during the year to come. But I'm not worried about the lymph node. That can be from a hangnail or a blister or scratch working on your car motor. Remember "your last risk" as a time when you shared love, treasure it and learn, and love safely and well. ...Read more

Lots of folks have white junk on their tongue -- tried dental flossing it off? Read about somatization. ...Read more

What does a high positive ELISA but negative ANA mean for a Lupus Screening? How are they different and how can 1 be positive and one negative?

What does a high positive ELISA but negative ANA mean for a Lupus Screening? How are they different and how can 1 be positive and one negative?

ANA: 1. ELISA is an immunoassay used to screen for ANA (high sensitivity, relatively low specificity). Can have false positive even with high titer. 2.If ELISA positive, usually a confirmation test will follow. Indirect Fluorescent Antibody Assay (IFA) is more specific test used as a golden standard to detect ANA. Hope that helps. ...Read more

Possible vasculitis: I would have an ANCA panel checked, especially with you saying you're having hematuria and proteinuria. There are a few conditions we refer to as pulmonary renal syndromes and they are all a type of vasculitis. Some of the names are Wegener's and Goodpasture's. ...Read more

With todays ultra sensitive modern ELISA tests, what use is the western blot for hiv? A few months ago i received a weakly reactive cmia HIV ag/ab test, a 4th generation HIV combo test, and this was followed by a negative western blot and a negative p24 t

False-positives: Screening tests are designed to be highly sensitive so they don't miss anyone with the disease. However, they can be so sensitive that they occasionally give a false-positive result. That is, the test appears positive for someone without the disease. The western blot, being time consuming and extra cost, is only used to make sure a positive is really a positive. Talk with your doc for more info. ...Read more
