Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON Tuberculosis Lab Test, is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin testing, this assay measures the immune system's response to specific TB antigens directly in a blood sample, which can simplify interpretation in people who have received certain vaccines.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Placentia
QuantiFERON testing works by measuring interferon-gamma released by sensitized white blood cells when they encounter TB-specific antigens.
A blood sample is collected and incubated with antigens derived from Mycobacterium tuberculosis, along with positive and negative controls that help validate each result.
If the immune cells recognize the antigens, they release interferon-gamma, which is quantified to indicate whether infection is likely present.
Because the antigens used are absent from most nontuberculous mycobacteria and from the BCG vaccine, the test tends to be more specific than traditional skin testing.
