I just had polymerase chain reaction (pcr) hiv test negative at 4 weeks 6 days, almost 5 weeks?

The doctor says theres no chance I would test positive later, he said there is a 1 in a billion chance which means its impossible, given that the chance of being infected per exposure is 1 in 10,000 even when the other partner is HIV positive. What do you guys think???

yes you need second opinion and always use a condom

get a second opinion,HIV and AIDs isn't something to second guess about

Avoid sexual contact until you are absolutely positive, and have another test run in six months.

Have you put yourself at risk in those 5 weeks?

If you have not, then you are fine. A PCR test is unlike your standard HIV antibody test. A PCR actually looks for the virus. They are very, very accurate tests. A negative test at 4 weeks means that you do not have the virus.

If are really worried, or have put yourself at risk, get another PCR test, but it's not like a doctor will interpret the results differently, or that a better brand of test will be used.

A negative PCR test does not mean that you are immune from HIV - it simply means you do not have the virus in your body at the time of the test.

The new series of tests that are run for HIV antibodies can detect the virus at no later than 13 weeks, but as your doctor stated there is a better chance of being struck by lightning and getting hit by a Semi at the same time than you testing positive.
