Why should a person that takes an hiv test today also take one in 3 months?
A person may be infected with HIV, but not test positive. It will take time for the virus to spread throughout the body and therefore when they first get infected they will often yield a negative test result since the concentration in the body at that time is still very small. After 3 months if a person tested negative the first time and negative the second time there is very little doubt on whether or not the patient has HIV. However, without the second test 3 months later a person who recently got infected before the original test would have shown a negative test result and actually had HIV.

What does a negative t statistic mean?
In statistics, the t-test is a measure of the probability of a particular event happening. It is based upon a normal (bell-shaped curve) distribution of probabilities. A negative number result for a t-test indicates that the probability calculated is to the left if you are graphing it on the bell curve. Importantly, it does not indicate a "less than zero" chance of an event happening.

When a male takes a urethra an swab test at the same time for chlamydia can both tests be false negative If so what is the percentage?
An estimate, from both tests showing negative, is less than a 2% chance you actually have the infection. The male urethral swab has a false negative rate of 15-20%. The rate of a false negative for the urine test has a false negative rate of 3-5.5%. So the chances of both being false negative, if they were done on separate days, is somewhere between 0.6% and 1.1%. If you had them done one right after the other on the same day, the risk of a false negative result goes up, as they couldn't have been done according to instructions.
