TPHA(Treponema Pallidum Haemagglutination)

The TPHA Test is a blood test used to detect antibodies against Treponema pallidum, the bacterium responsible for syphilis.

This test helps healthcare professionals investigate syphilis infection and is commonly used as a confirmatory treponemal antibody test following initial screening.

What Does This Test Check?

• Detects antibodies against Treponema pallidum.

• Supports the investigation of syphilis infection.

• Helps confirm reactive syphilis screening results.

• May assist in evaluating previous or current exposure to syphilis.

• Supports clinical assessment alongside other syphilis investigations.

Sample Requirements

• Sample Type: Clotted Blood or Serum

• Required Quantity: 2–3 ml

• Department: Serology / Immunology

Patient Preparation

• Fasting is generally not required unless instructed by your doctor or laboratory.

• Inform your healthcare provider about any previous syphilis diagnosis or treatment.

• Follow any specific sample collection instructions provided by the laboratory.

Important Information

A positive TPHA result indicates antibodies against Treponema pallidum but does not necessarily mean an active infection. These antibodies may remain detectable even after successful treatment. Results should be interpreted alongside clinical findings and non-treponemal tests such as VDRL or RPR.

Reporting Time: To be confirmed by the laboratory.

Please confirm test availability and sample collection requirements with the laboratory before booking.
