Is hepatits b can be detect if I will have a syphilis test? Plzz answer doctors. Tnx

No: Syphilis is a sexually transmitted disease caused by a bacteria called Treponema pallidum. It is not related in any way to Hepatitis B (which is a virus). Both are sexually transmitted, however.

Need expert advice. After sex, how long should you wait until you get a syphilis test to make sure the virus has already shown up?

Early syphilis: Initial syphilis manifests on the average of 21 days as a painless ulcer in mucosa/genital areas... If this lesion was missed becuase the ulcer is normally painless I would get the test in 2 months. That being said, I would also get a test for other sexually transmitted diseases like hepatitis C and B and HIV. Syphilis is a spirochete -- a type of spiral-shaped bacteria and not a virus. ...Read more

Wb indicating protein 41 active. I read its a lot of controversy about p41.Dfm showed spirochetes and gemmas. Syphilis test negative. Is it lyme?

Be skeptical: Lyme disease is not transmitted sexually, but through bites from infected ticks. Diagnosis using western blot is complicated and requires review of the entire blot and assessment of your other symptoms and risks. Dfm reliability is dependent on the person doing it, and may be manipulated in an attempt to sell you unproven or even dangerous treatments for lyme disease. ...Read more
