Handjob at massage parlor. tested for HIV with 4th gen test at 4 and 6 weeks both neg. Also had a negative HIV RNA at 20 days. Are these conclusive?
HIV: HIV is transmissible through body fluids. Unless you had an open sore on your penis and the massager who gave you the "hand job" had an open sore, that were in contact, there is minimal to almost no chance you contracted hiv from that encounter. The tests are good, but remember any HIV exposure can take several weeks to seroconvert to a positive blood test. ...Read more
Hiv pcr plasma at 8 weeks, hiv antibody test at 6 weeks post possible exposure. how reliable and accurate? could it have detected if there coinfection
No evidence of HIV-1: This is good news - PCR tests are extremely sensitive, so if 'nothing' was found at 8 weeks, I'm 99.9% sure you don't have HIV. In addition, you have a second test -for HIV antibody that is also negative 6 weeks after a possible exposure. So this means you're absolutely HIV free - just remember to be 'safe' out there. Talk to your doc about the best ways to protect yourself and others. ...Read more

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.
HIV testing & 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. ...Read more
Hiv pcr plasma test at 8 weeks and antibodytest at 6 week post exposure negative. How accurate, reliable? can they detect if coinfection with hepatit
1.How reliable, accurate antibodytest at 6 week post possible exposure?
2.How reliable, accurate pcr plasma test at 8 weeks even if viral load low?
HIV: The antibody test is pretty reliable, and would be reliable 6 weeks post exposure. It would theoretically be able to test positive after 5-10 days post exposure. The RT-PCR test is highly sensitive and specific but a second test should be done if the viral load was low to rule out a false positive test. A repeat RT-PCR and viral load should be redrawn and this would be a true positive if higher. ...Read more
Negative 4 gen HIV including PCR and 8 STDs at 29 days. Later at 5 months same test,negative. Negative HIV antibody at 7 months. All conclusive?
Yes, conclusive: The 4th gen HIV tests are conclusive any time 4 weeks or more after the last exposure, so your first test was conclusive for HIV; the other HIV tests were superfluous. Depending on which STDs were tested, some of those were conclusive at 4 weeks, and the others probably conclusive at 5 months. You can stop testing for HIV and any STDs based on an exposure 7 months ago. Best wishes. ...Read moreSee 1 more doctor answer
37 weeks pregnant and tested positive for HSV 1 igg. Any special considerations during the rest of pregnancy and delivery ?
I took a HIV antibody test at 13 and 15 weeks and a HIV PCR at 7 weeks and test negative , what are my odds of having false negative ?
What is the window period for Modern day HIV 4th generation tests. Many HIV specialists consider this conclusive at 28 days.? And CDC says 3 months?
Concensus is 4 weeks: Both biological principles of the test and expert opinion favor 28 days. Few if any HIV experts report ever having a patient with new HIV who didn't have a positive 4th generation test by 4 weeks. The main exception may be when post exposure prophylaxis with anti-HIV drugs is given but doesn't work. Even then, it's probably rare. Many official agencies take conservative stances and always have. ...Read more
2 ELISA tests for HIV done at 3 months and 6 months of exposure, is it a conformation that I dont have HIV if both tests are negative?
Almost certainly: The ELISA tests detect antibodies to HIV and can appear as early as 2 weeks after infection but, if not detected by 6 months, it's 99% certain that you haven't been infected. That doesn't necessarily mean you weren't exposed however, It could mean you were lucky. Stick with protected sex unless you are at least 99% certain your partner isn't infected either. ...Read more
Can i do PCR test for HIV, Hepatitis , HPV 18,16,12 after 32 days of risk exposure? The Result will be accurate and reliable? Peace of mind?
Yes and no: AT 32 days, you should not have a PCR test for HIV, only the standard antigen-antibody test (4th generation). It will be conclusive. Its too early for hepatitis, though; wait until 6 weeks (although hepatitis is so rare after any single exposure that most experts don't recommend testing at all). Don't waste money on HPV testing; it takes several months to show up, and everybody gets HPV anyway. ...Read more
Hi. Just wanted to know how accurate is a HIV DNA PCR test at 6 and 21 days after exposure. Both tests came back as not detected.?
Negative: The overwhelming probability is that you are negative. This is a very accurate test and rapidly becomes positive in infected individuals. The test actually measures rna. This virus is call a retrovirus because in the cell it is converted to dna and then intercalated into the cell genome. ...Read more
1.How reliable, accurate second generation antibodytest at 6 week post exposure?
2.How reliable, accurate pcr plasmatest at 8 weeks if viral load low
Together, 100%: 1) Probably around 95-98% 2) Probably 95%. The combination of the two tests is 100% proof you don't have HIV. By 6-8 weeks, everyone with HIV has the virus by PCR, or antibody, or both. There are no exceptions. For sure you don't have HIV. Stop worrying and stop testing. Good luck and stay safe. ...Read moreSee 1 more doctor answer

I have read on that 6 weeks after a possible exposure is good for a syphilis test, mine was done at 39 days instead of 42. Still valid? 3 days matter?
Here are some ...: Generally speaking the number or values as quoted in the literature are so-called normal "range" to cover some 95% of cases and should be used as references of daily medical practice and living, not at 100% like machine. In practice, it's good idea to combine high vigilance and keen diligence to assess history, practice safe sex, and rouse professional alertness so to test timely - not rigidly. ...Read more
2-4 weeks: There is a window period during which time you might not test positive for syphilis but still be infected. This window period can vary by type of test -- and probably from person to person. The syphilis lesion (chancre) usually appears 1-3 weeks after exposure and the vdrl/rpr blood test usually is reactive 1-2 weeks after the lesion appears. ...Read more
Depends on timing,Sx: The answer depends on the timing of possible exposure to syphilis & any symptoms (Sx) that you may have. So, it's impossible to answer your question here. Use HealthTap Prime or talk to the doctor who ordered the test. CIA, or chemiluminescence assays, are REACTIVE when treponemal (bacteria that causes syphilis) antibodies detected. It can be Non-Reactive in early stages (false neg) despite Sx. GL ...Read more
Antibodies tested: The test is for antibodies, which need time to show up post exposure. Fluorescent treponemal antibody absorption (FTA-ABS) test. The FTA-ABS test checks for antibodies to the bacteria that cause syphilis and can be used to detect syphilis the first 3 to 4 weeks after exposure to syphilis bacteria. The test can be done on a sample of blood or spinal fluid. ...Read moreSee 1 more doctor answer
