Is hiv 4th gen test taken 5 weeks after pep treatment considered conclusive?

To be sure a test should be done at 6 months after exposure. A negative result earlier is good but not conclusive. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
