Tb Gold Quantiferon

The TB Gold QuantiFERON Test (QuantiFERON-TB Gold) is a blood test used to detect immune system responses to Mycobacterium tuberculosis, the bacteria responsible for tuberculosis (TB).

It is an Interferon-Gamma Release Assay (IGRA) that measures the immune response to specific TB antigens. This test helps healthcare professionals identify TB infection, including latent tuberculosis infection.

What Does This Test Check?

• Detects immune responses to specific tuberculosis antigens.

• Helps identify possible TB infection.

• Supports the assessment of latent tuberculosis infection.

• May be recommended for individuals with suspected TB exposure.

• Helps screen individuals at increased risk of tuberculosis infection.

Sample Requirements

• Sample Type: Special blood collection tubes required for QuantiFERON testing.

• Required Quantity: To be confirmed by the laboratory.

• Department: Immunology / Microbiology

Patient Preparation

• Fasting is generally not required.

• Inform your healthcare provider about previous TB diagnosis or treatment.

• Follow the laboratory's specific blood collection instructions.

• Special collection tubes and correct sample handling are essential for accurate results.

Important Information

A positive QuantiFERON result indicates TB infection but cannot distinguish between latent and active tuberculosis. A negative result does not completely exclude TB infection, particularly in individuals with weakened immune systems. Further evaluation, including clinical assessment, chest X-ray, or sputum testing, may be required.

Reporting Time: To be confirmed by the laboratory.

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