Hi there. I just did a test 16 weeks ( 4 Months) after exposure, for Hepatititis B S Ag, Hepatitis C Virus, VDRL/TPHA (Syphillis) & HIV, all came back negative also the Urinanalysis report and blood analysis report is good as per doctor sayings. Should I consider other test to detect STDs, which are not listed above and should I repeat the above test later or it is conclusive? Your reply will be kindly appreciated.
