Did my hiv antibody-antigen combo test after 10 weeks of possible exposure came out negative do i need to retest or this test is satisfactory.

Should be ok: If the exposure was unprotected sex then first off it would be extremely helpful if your partner does not have known HIV. But I assume you don't know this so your test is a reliable method of determination. However if you had unprotected sex more than once- your risk is obviously higher so try to practice safe sex 100% of the time.

Recheck at 6 month: Given many variables, 10 weeks negative is good but not reliable. Both (a) check out/verify the false negative rate with the lab, given the test kits they use to do the testing (no test is 100% accurate in ruling-in or out plus actual accuracy involves additional issues, see: bayes' theorem) and recheck tests at 6 months after the possible exposure.
