Question 1

how long does one have to wait, for hiv-1 dna pcr results?

Accepted Answer

Just few days: Depends how fast the genetic lab receives the specimen, HIV virus dna analysed and identfied by pollymer chain reaction, or PCR making copies of sequence  and identifies.

Question 2

how long should i wait to get hiv 1 dna rna test?

Accepted Answer

Need more info : To give an answer to your question more information is needed.  Did you recently start medications to treat hiv, then the answer is after about 1-2 months.  Did you recently engage in a high risk activity, such as unprotected anal intercourse?  In that case, i would advise first and foremost to use protection in the future and to be tested as soon as possible.  Hiv may show up as soon as 7-10 days.

Question 3

is hiv 1 pcr dna @25 days, lab ab/ag @25 days, @38 ab/ag lab test, @48 days lab ab/ag, and at 12 weeks (85 days) antibody and pcr qualitative hiv 1 dna, all negative? conclusive??

Accepted Answer

: Yes conclusive, if you haven't taken anti-HIV drugs since the exposure you are concerned about.

Question 4

do hiv 1 and hiv 2 dna differ form each other?and is there seperated dna pcr tests for each or one is enough to catch both?

Accepted Answer

You mean RNA: These are RNA-based retroviruses. The PCR assays for the two strains are distinct.

Question 5

is hiv-1-pcr quantitative and hiv rna pcr quantitative same tests?can dna pcr test be quantitative?

Accepted Answer

HIV testing: Yes.  Viral testing can be qualitative or quantitative. Most HIV RNA testing is quantitative.

Question 6

how many types of hiv are there?i did hiv dna pcr for hiv 1 only i'm afraid if i'm infected by other types.

Accepted Answer

HIV risks: There are two major strains of HIV in the world - HIV-1 and HIV-2.  Almost all infections are HIV-1 unless you live in W. Africa where there is some HIV-2.  If your test was negative then that is great. You should still be careful though because HIV infection requires life long medication to manage it.  Probably best to get follow up with your doc. There are lots of ways to have safe sex-b careful

Question 7

i did hiv dna pcr and results came negative after 21 days but only for hiv 1 my question is if i had hiv 2 would this test detect it as well?

Accepted Answer

Yes: This test is specific for both Types 1 &amp; 2,

Question 8

can a quantitative hiv dna test that looks for the virus differentiate hiv 1 from hiv 2 ?

Accepted Answer

No: This is determined predominantly by antibody testing rather than by PCR for HIV RNA (This is an RNA virus). The latter test does not differentiate serotypes. Type 2 is very rare outside of Africa and seems more difficult to transmit. There are also numerous subtypes of both Types 1 &amp; 2 and this becomes quite complex since this virus mutates continuously.

Question 9

does dna pcr test for hiv 1&2 lose sensitivity over time? how accurate can a negative result for dna pcr be on checking at 89 days post exposure?

Accepted Answer

No sensitivity loss: These tests do not lose sensitivty over time. A negative result at almost 3 months is almost 100% conclusive. However, to reach 100% certainty, you also need an antibody test, if not already done.

Question 10

got tested after 45 days, my results hiv-1&2 antibodies-non reactive.hiv-p24 antigen-non reactive.hiv dna pcr-not detected.am i clear?please advice.

Accepted Answer

Likely: It would be prudent to retest at six months after exposure. If the HIV nucleic acid test is negative then, you would be free.
