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 the bacterium that causes tuberculosis. Unlike skin tests that require a follow-up visit to read the result, this assay measures the immune response directly in a blood sample, which can simplify the testing process and reduce subjectivity in interpretation.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Hialeah
QuantiFERON technology works by measuring interferon-gamma released by sensitized T cells after exposure to specific TB antigens.
The test uses a set of blood collection tubes. One tube contains no antigen and serves as a negative control, another contains mitogen as a positive control, and the remaining tubes contain TB-specific antigens. After incubation, the amount of interferon-gamma produced in each tube is quantified.
Results are reported as positive, negative, or indeterminate. A positive result suggests that the immune system has been exposed to the tuberculosis bacterium at some point. It does not by itself distinguish between latent infection and active disease, so clinical evaluation and additional testing are necessary to determine the appropriate next steps.
Because the assay relies on a blood draw rather than a skin reaction, it avoids the need for a return visit to have a skin test read. It also does not cross-react with most nontuberculous mycobacteria or with the BCG vaccine, which can cause false-positive results on older skin tests.
