Description
Why It’s Done:
This test is typically used to:
• Confirm a diagnosis of syphilis after a positive screening test (such as RPR or VDRL)
• Distinguish between current and past infection by detecting both IgM (early) and IgG (later-stage or previous infection)
• Diagnose congenital syphilis in newborns (if the mother is infected)
• Evaluate unexplained symptoms such as skin rashes, neurological issues, or genital sores that may be due to syphilis
• Monitor treatment response in confirmed syphilis cases
Preparation:
• Fasting: Not required
• Medications: No specific medications interfere, but inform your doctor of any immunosuppressive drugs or antibiotic treatments taken recently
• Blood Sample: A simple blood draw is required from a vein in your arm
• Other Notes
