Test Overview
Nontreponemal flocculation procedure (RPR).
Screening test for syphilis
Nonreactive
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Nonspecific positive reactions may be found in SLE, malaria, infectious mononucleosis, hepatitis, leprosy, brucellosis, atypical pneumonia, typhus, and other infections. Reactive tests due to related treponemal infections (bejel, pinta, or yaws) may also occur. A reactive result in a newborn may be due to passive transfer from mother's blood.
