brother ,it is for syphilis ,it is sexually transmitted disease(STD)
. I was 100% sure I cant have it. they first took only VDRL but some times it results in FALSE POSITIVE,so they need further confirmation. so they again call for blood samples. but one thing is very strange that IOM said my VDRL is unknown but for my own confirmation ,i did VDRL here in fsd but it resulted in negative. I think if u have blv in urself,then it will be cleared as it is STD. and it is the only way for it to be transmitted.
