I did a blood test and got the result of vdrl non-reactive. What does this mean?

No syphilis. Vdrl (veneral disease research laboratory) is a non-treponemal specific blood test that is widely used to screen populations for syphilis. A negative test if reassuring; a positive (reactive) test has to be followed by a treponemal-specific test such a fluorescent treponemal antibody absorption (fta-abs).
