Thanks for querry to HCM
As it is well known VDRL
is a nontreponemal test designed for diagnosis of a sexually transmitted disease SYPHILIS
VDRL is a very nonspecific test. TPHA is the specific test for syphilis. One of the major drawback of VDRL is that it gives false positive result in a battery of situations called Biological false positives.
VDRL is again of 2 types
Quantitative VDRL in most situations has the ability to exclude the biological false positives.
Get repeat testing done, if you are exposed to risk factor of a STD
(you have not mentioned any exposure history).
Nothing to worry if it is a biological false positive.
All the best
