Hi, I'm 24 years old. I have syphilis. The doctor prescribed me doxycycline (100mg twice a day for 15 days). Before treatment I made blood tests: This is results (Before treatment):
VDRL 1/2
FTA 1/450
TPHA 1/5120
FTA-ABS positive
PS: I don't remember any symptoms. And I finish taking doxycycline. Befor I don't I treated previously for syphilis
1. What stage of syphylis is?
2. What does it mean high value TPHA 1/5120 and another low?
3. Whether the treatment (doxycycline for 15 days) will be effective in this case?
