Question 1

hiv antibody testing (meia) possible everywhere?

Accepted Answer

MEIA HIV ANTIBODY TE: Yes in us it is available in every lab.

Question 2

how accurate is hiv antibody testing after 3 years of exposure?

Accepted Answer

Very accurate: If performed properly, oraquick has shown consistently verifiable results.  You can always check with your doctor for additional testing (such as antigen or PCR) if you're really concerned.  But, all things being equal, the oraquick tests are as reliable as the antibody tests we use in the office.

Question 3

can results from hiv antibody testing be reliable before the 3 & 6 month mark? i was tested at 6weeks postexposure. also, can the 3months b reliable?

Accepted Answer

HIV testing: 95% of those tested at three months should be accurate. But to get 100% that would be six months.  If you have a high risk exposure this can be 100% tested at 21 days post exposure with the HIV RNA test.

Question 4

why do some clinic say hiv 4th gen antigen/antibody testing is very accurate at 21 days while some say 28 days. is it because they use different 4th gen kits?

Accepted Answer

HIV test results: It just depends on what they mean by "very accurate". About 90% of newly infected people have positive AgAb HIV tests by 21 days -- very good by standards of many diagnostic tests for various medical conditions, but most persons at risk for HIV want more certainty, and these tests take 28 days to reach 98% reliability, 6 weeks for 100%. Performance is the same for all available HIV AgAb tests.

Question 5

what is the accuracy of p24 antigen and antibody hiv testing 4-6 weeks post pep testing? for something incredibly minor, would this be reliable?

Accepted Answer

Prob conclusive, but: This test probably will detect all HIV infections 4-6 weeks after completing PEP. However, it isn't certain. There has been no research on whether and how long a positive test may be delayed if PEP doesn't work. Therefore, most experts recommend a final test at 3 or even 6 months. This is one reason PEP should be done only after a high risk expsoure, because it prolongs uncertainty and anxiety.

Question 6

what is the accuracy of hiv testing (antibody and antigen) 6 weeks post pep? i had all tests (neg) including the pcr rna test at 22 days post pep.

Accepted Answer

HIV testing &amp; RNA: Read the CDC updated recommendations on HIV testing. The rationale for this test being available is that HIV RNA is detectable in plasma before antibodies. A safe approach is to be tested after the eclipse period after potential exposure when no RNA nor antibodies to HIV can be detected.  The RNA test is effective around 10 days after infection but seroconversion to antibodies may take 3 months.

Question 7

diagnosed with covid weeks ago with classic symptoms, but recent labcorp antibody testing showed negative. is this a correct result? am i not protected? my symptoms have greatly improved?

Accepted Answer

Agree with Dr. F: Take Covid-19 vaccine even if you develop antibodies from the infection.
Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
Get HPV and Covid vaccines. Wish you good health!

Question 8

hi there,

how do we go about getting a referral for antibody testing?

Accepted Answer

Antibody to what?: If you are asking about antibody to Covid, what will you do with the results. It is generally better to let your doctor decide if a test is warranted.

Question 9

why does hcv testing have s/co ratio of 0.0-0.9 for negative reading? arent antibody testing a positive or negative result to know if you do or do not have the virus? if one has result of 0.1, shouldnt that mean they have some level of it?

Accepted Answer

: The test doesn't work that way. For almost all tests of the type called enzyme immunoassas (EIA), an index value below the positive cut-off (usually 0.9 to 1.1) is totally negative. The same specimen tested 10 times could give 10 different numbers, and all would be equally negative, meaning no antibody in the sample. Same for many other EIAs, such as tests for HIV, HSV and many more.

Question 10

what are the testing options for herpes 2?  i've read about igg and igm, with questions around the reliability of igm antibody testing.  how soon can tests be performed?  i'm at 32 days post potential exposure, no outbreaks, but wondering if exposed?

Accepted Answer

Herpes: All these tests are within the 90th percentile in accuracy and can be done probably after 72 hours of exposure. Good Luck
