Negative hiv 4 generation combo lab test 65 days after unprotected sex. how conclusive is this test. cdc guidelines says 45 days with 4 generation?

Good result: In all likelihood you did not get infected. To be sure, you should get a HIV nucleic acid test at 6 months after potential exposure. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
