Brief Answer:
window period passed, result accurate

Detailed Answer:
HI, thanks for using healthcare magic

HIV tests have window period. The window period is the time from possible infection till when a test can accurately detect the particular infection.

After this window period has passed then the test result is considered final and accurate.

The window period for the 4 th generation tests is 2 to 3 weeks generally, 4 weeks at the maximum.

This means that at 7 months ,the result would be definitive and accurate.

If it is negative at this point, it is truly negative, you are not infected.

I hope this helps, feel free to ask any other questions

Doctor thank you for your answer ... Another question.... Would taking valtrex affect my heptitis b test results and syphilis tes results ... These were done after 5 months of exposure ...

Brief Answer:
should not have any effect

Detailed Answer:
HI,

Syphilis is caused by a bacteria so should not be affected by an anti viral drug such as valtrex.
This has a window period of up to 3 months, so a 5 mth result would be definitive and accurate for you.

Hepatitis b is a virus but despite this fact , the use of valtrex would not prevent detection of the markers of hepatitis infection.
The first marker can be detected by 4 to 10 weeks so by 5 mths you would have a definitive result.

Please feel free to ask any additional questions

Doctor just one last question the exam that was done hepatitis b core ab , igm this came non reactive , is this test done by the doctor right ? she told me that yes and to move one

Answered by Dr. Dr. Michelle Gibson (5 hours later)

Brief Answer:
this is one of the first antibodies to form in an infection

Detailed Answer:
HI

Yes, this test is fine.

There are different tests that can be done to detect the presence of hepatitis b.

There are different types of antibodies, IgM antibodies is one that is formed soon after a person has become infected.

If you had been infected with hepatitis b recently , then this antibody would be present.

A non reactive test means that this infection was not detected.

If anything else unclear, you can feel free to ask

Thank u ... I'm very cleared with hiv and hepatitis b ... Just to be cleared with clammydia and gonorrheah even if I was taking valtrex at the time of the test (swab test ) my results would be conclusive ?

Brief Answer:
would not have an effect

Detailed Answer:
HI

Sorry about the late reply.

Both are those infections (chlamydia and gonorrhea) are caused by bacteria not viruses.

This means that they would not be affected by anti viral medication such as valtrex.
This medication would not have any effect on these tests.

Hope this reassures you
