If i took oraquick 6.5 weeks and results were negative was the test accurate or should i get another one.

Not quite conclusive: This test is quite reliable at 6 weeks but once in a while needs 3 months to turn positive. If your risk was quite high, like unprotected sex with a known infected partner, get tested again at 3 months. Or have a blood test; all the blood tests, either rapid or lab based, are conclusive by 4-8 weeks, depending on which test. Blood tests are preferred when concerned about a particular exposure.
