Immunoglobulin Release Assay (IGRA)?

10 October 2013 1 5K Report

Immunoglobulin Release Assays *IGRAs( are the new tests for Latent Tuberculosis (LTBI). Both seem to be reliable. There are two IGRAS: T-spot and QFT-TB Gold. However, one seems to have better sensitivity and specificity. Are there any data, other than those from the companies, that show the difference between both assays?

LBTI USE TO BE DETECTED BY USING Skin tuberculin test replaced by quantiferon which is much more sensitive by detecting from blood sample.
