How conclusive is a hiv test done with a 4 generation combo test at 6weeks after exposure to hiv?

See below: It is good if the result is negative. To be sure you should get a HIV nucleic acid test at 6 months after 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.
