Question

for knowing things

Answer 1

Those are non interpretable results. Those are dilution results. The VDRL test can test positive for anything, as they are screening tests. Other conditions that test positive for the VDRL test is hepatitis and other viral problems.
You will need another test called the FTA- ABs, which is a treponemal test specific for the treponema organism of syphillis., that or the microhemmagglutination assay for the antibodies to t.pallidum (MHA-TP) and the HATTS tests.
