I am not sure. Try to google it, that is what I would do to help you further on this.
what is the difference between VDRL and TPHA?
When the number starts to drop it shows that treatment has worked.
it is said that syphilis is a curable diseased? how will know that I am already cure??? when it may not drop to 1 for years???
1:4 is not all that high, The number may not drop below 1 for years.
i already got the result for my second test. i was tpha positive and my rpr is 1:4. I was already injected w/ benzathine 2.4mu and advice to hav it again for the next 2 months. Is 1:4 a critical stage? what is the accepter titer to say that i am already cure?
You can't get it from saliva. Syphilis is only transmitted from direct contact with a syphilis sore.
why is syphilis falls under STD when you can acquire it true saliva as well?
False positives do happen. They can happen for many reasons, can't say exactly why.
