Florescent Treponemal Ab (FTA-ABS)

Introduction to FTA-ABS

The Fluorescent Treponemal Antibody Absorption (FTA-ABS) test is a crucial diagnostic tool used primarily to detect syphilis. This test identifies antibodies produced in response to the Treponema pallidum bacterium, the causative agent of syphilis.

How the FTA-ABS Test Works

The FTA-ABS test involves taking a blood sample from the patient. The sample is then exposed to the Treponema pallidum bacteria. If antibodies are present, they bind to the bacteria and fluoresce under ultraviolet light, confirming the presence of syphilis.

Importance of FTA-ABS

This test is highly specific and sensitive, making it an essential part of syphilis diagnosis. It is especially useful in confirming syphilis in cases where other tests may not be as definitive.
