Hello, Thanks for trusting Healthcaremagic! I have gone through your query and I can understand your concerns.
VDRL is a screening test for syphilis. VDRL is not a very much sensitive and it can cause false negative results(Condition in which test shows negative results even though you have disease). The given test result is negative for syphilis,but you had a past history of syphilis it could be a false negative result. So we have to do a more sensitive tests like TPHA or FTA-ABS which are treponemal specific and confirmatory test for syphilis.
Hope I have answered your query. Wishing you good health.
