Blood test to detect tuberculosis (TB) infection.
About this treatment
The QuantiFERON-TB Gold test is a blood test that helps detect latent or active tuberculosis (TB) infection. It measures the immune system's response to TB bacteria by detecting the release of interferon-gamma (IFN-γ) when TB-specific antigens are introduced to a blood sample. Unlike the traditional tuberculin skin test (TST), the QuantiFERON-TB test is more specific and does not require a follow-up visit for reading results. It is crucial to plan ahead and allow sufficient time for the TB test, as it is typically not available on a same-day basis. The turnaround time for obtaining test results is usually around 10 working days, including 3-4 days of incubation. This test requires a special Quantiferon TB Gold Kit and 4 vials of blood will be collected.

Who is this for?
Anyone wanting to check specific health markers. People monitoring known conditions or treatment effectiveness. Those who want targeted testing rather than a comprehensive panel. Individuals following up on previous abnormal results or investigating specific symptoms.
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.

Biomarkers Tested
2Vitamin B2 (Riboflavin) is important for energy production and cellular function. Deficiency can cause skin disorders, anemia, and fatigue.
Measures interferon-gamma (IFN-γ) release in response to TB-specific antigens.
