Data is representative. TEST TYPE: non-treponemal (RPR,VDRL)|treponemal (rapid tests, TPPA)|patients positive on both. (1) Syphilis positivity is defined as women both TPHA reactive and with detectable RPR titer, however many did not get RPR test. For these cases we assume the rate of psotivity would be the same as it was for cases who got RPR.  Percent of PHA positive cases with a detectable RPR titer = 81.5%  (#RPR positive/#had RPR test, source is PMTCT database). SOURCE: National programme data.
