About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Altadena
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, a bacterium that primarily affects the lungs but can involve other parts of the body.
The infection spreads through the air when a person with active respiratory TB coughs, speaks, or sings, releasing tiny droplets that others may inhale. Not everyone who inhales the bacteria becomes ill; many develop a latent infection in which the immune system contains the organism without causing symptoms.
Latent TB infection carries no signs of illness and is not contagious, yet the bacteria remain alive in the body. Without treatment, a portion of latent infections can later progress to active TB disease, which does produce symptoms such as a persistent cough, fever, night sweats, and weight loss.
The QuantiFERON test measures the release of interferon-gamma by white blood cells when they are exposed to specific TB antigens in the laboratory. This approach distinguishes TB infection from most non-tuberculous mycobacteria and from prior BCG vaccination, which can complicate skin test interpretation.
