Whenever you have to go abroad, you need to do the VDRL test according to the rules of some countries.

The VDRL test is a screening test for a disease called Syphilis.

Syphilis is a sexually transmitted disease caused by a bacteria called Treponema pallidum.

Anyone who gets VDRL test positive gets nervous and worried that my VDRL test has come positive.

But Syphilis is not proven by the VDRL test being positive. For this, another test has to be done, which is named the TPHA test.

The full form of TPHA is Treponema pallidum hemagglutination test, which is a diagnostic test for syphilis.

If both the VDRL and TPHA tests are positive, then only syphilis is diagnosed and such a patient is treated.
