Not really. HIV tests are very differential. However, HIV is not a disease with a linear progression. Because the virus mutates very fast, it makes rise and falls especially at the beginning but later too, so at any point it is possible to get a false negative. Tests are only safe after the first month, then it is better to repeat it at the third and perhaps the sixth month. If a person is in a high risk group because of "sleeping around" or "sharing needles" it is better to get tested at least once in every three months. There are also rapid tests that you can buy and carry around, you know like pregnancy tests.
Not usually. If you are concerned you can always get another test done by another facility and explain before hand what your concerns are. Just be sure they don't go through the same analysist for results
