2017年8月2日 · QFT-Plus is an IFNγ release assay, commonly known as an IGRA, and measures the cell-mediated immune response to specific TB antigens in whole blood. The test employs standard phlebotomy procedures using whole blood to make sample collection easy and fast.

2024年5月9日 · TB blood tests (interferon-gamma release assay or IGRA) are methods of determining whether a person is infected with TB bacteria. TB blood tests measure the immune response to TB proteins in whole blood. Two TB blood tests are commercially available and approved by the U.S. Food and Drug Administration.

QuantiFERON-TB Gold Plus is an in vitro diagnostic test using a peptide cocktail of CD4+ and CD8+ T cell antigens to stimulate cells in heparinized whole blood.

ichromaTM IGRA-TB is a qualitative fluorescence immunoassay (FIA) for detection of interferon gamma (IFN-γ) released in response to in vitro stimulation by Mycobacterium tuberculosis specific antigen in human whole blood. It is useful as an aid in management and monitoring of Tuberculosis infection. For in vitro diagnostic use only.

QuantiFERON (QFT) is an interferon-γ release assay (IGRA) that aids in the evaluation of tuberculosis (TB) infections (latent or active) 1 and is recommended by the CDC as an alternative to the tuberculin skin test (TST) in certain situations. This modern alternative offers improved performance and quicker results.

QuantiFERON®-TB Gold Plus, 1 Tube - This test is a blood-based interferon-gamma release assay (IGRA) used as an aid in the diagnosis of Mycobacterium tuberculosis infection. It is an immune response-based, indirect test for M tuberculosis infection (including disease) and is intended for use in conjunction with risk assessment, radiography ...

IGRA-TB is a unique product that combines a highly specific cell-mediated immune response (CMI) against MTB and a sensitive lateral flow detection system. It can help fight tuberculosis by detecting latent TB in the simplest, fastest, and most accurate way.

Interferon gamma release assays (IGRAs) are relatively new tests for tuberculosis (TB) infection. These tests measure the patient’s immune response (interferon gamma release) after stimulation of white blood cells in a test tube with 2-3 relatively TB-specific antigens.

QuantiFERON®-TB Gold Plus, 4 Tubes, Draw Site Incubated - This test is a blood-based interferon-gamma release assay (IGRA) used as an aid in the diagnosis of Mycobacterium tuberculosis infection. It is an immune response-based, indirect test for M tuberculosis infection (including disease) and is intended for use in conjunction with risk ...

2010年6月25日 · Control materials and antigens for QFT-GIT are contained in special tubes used to collect blood for the test, thus allowing more direct testing of fresh blood. One tube contains test antigens that consist of a single mixture of 14 peptides representing the entire amino acid sequences of ESAT-6 and CFP-10 and part of the sequence of TB7.7.
