Until 2001, the only test used to diagnose latent tuberculosis infection (LTBI) was the tuberculin skin test (TST). Test Includes: Viability of lymphocytes to help determine impaired T-cell function. If it comes to be positive, then you need to get a pulmonologist opinion, about whether treatment needs to be taken. The service should not be used for medical emergencies. for progression to active TB. Elevated levels of interferon gamma may occur due to the presence of heterophile antibodies or intrinsic gamma interferon secretion in the patient. MITOGEN-NIL >10.00 IU/mL KS TB-NIL 0.00 IU/mL KS The Nil tube value is used to determine if the patient has a preexisting immune response which could cause a false-positive reading on the test. The laboratory monitors indeterminate result rates as part of its overall quality assurance program. Lymphokines act to attract additional immune cells to mount an immune response, for instance in stimulating B cells to generate antibodies against the invading pathogen.
