Hello Doctor, I recently had a TPHA test, and the results show a reactive obtained value but non reactive units. I am confused and would like to know whether this means the test is positive or negative, and what the final interpretation of the report would be.

A TPHA test Reactive means the test is positive, indicating past or present infection with syphilis. TPHA remains positive for life, even after treatment. To confirm if it is an active infection, you will need a VDRL test to check the activity level. Please consult your doctor for further evaluation and treatment if required.

Hi. My VDRL is positive and TPHA is 1.0 negative. In October, my report showed this. The doctor gave 4 injections of 1.2 lakh each over 2 weeks. Before 2008, my VDRL was active and TPHA was not active. The doctor gave 2 injections of 2.4 lakh. From 2008 to August 2017, I did not have any ulcers. In 2017, one night I slept and in the morning I noticed a black spot on the shaft of my penis. The next day an ulcer appeared on the skin and after 4 days it went away, but the skin color did not return to normal. Recently, I have much itching and burning. Please help. I am currently in KSA.

I have never had sexual activity. Recently, during treatment for an anal fissure, I got a blood test. The results were: VDRL: Reactive TPHA: 10 (Negative) TPAB: 0.18 (Negative) I have no symptoms apart from the anal fissure, which is now cured. I am worried about these results. Could you please suggest what my next steps should be?
