Saying moderately reactive is like saying "im a little bit pregnant". Kinda need more info! Like AJ said, he needs to be tested for chlamydia, gono and HIV as well (should be common practice during a routine test).
They should have confirmed his VDRL with a TPHA or FTA-ABS test. Where is he getting these tests? What does "moderately reactive" mean? It should have some kind of numeric value to it.
If he had unprotected sex, is he also testing for things like gonorrhea and chlamydia?
