665. Lower Indeterminate Rates and Resolution by Retesting Using a Single Lithium-Heparin Tube Blood Collection Method for the QuantiFERON®-TB Gold Plus (QFT®-Plus) [PDF]

Open Forum Infectious Diseases, 2020
Abstract Background The QuantiFERON-TB Gold Plus (QFT-Plus) test is an assay for detecting a cell-mediated immune response to M. tuberculosis (MTB). The assay measures the in vitro quantitative IFN-γ responses to MTB or control antigens in an incubated blood sample.

Comparison of Rifampin and Isoniazid for Latent Tuberculosis Infection in Kidney Transplant Candidates: Focus on Tolerability and Treatment Completion. [PDF]

Transpl Infect Dis
This study comparing 4‐month rifampin with 9‐month isoniazid for latent tuberculosis in kidney transplant candidates showed higher treatment completion rates and no transaminase elevations in the rifampin group. However, some patients experienced an increase in blood pressure while taking antihypertensive medications known to interact with rifampin ...

P164 Qft-plus: do the peptides in the tb2 tube induce a t suppressor response in some subjects? [PDF]

Early detection and screening in TB, 2017
Introduction The revised QuantiFERON-TB Gold assay (QFT-Plus) has an extra tube (TB2), containing peptides thought to stimulate CD8 +T cells; TB7 antigen is no longer included. The test is designed to detect latent tuberculosis infection. Hypothesis Levels of interferon-γ in TB2 should always be greater than TB1 Methods QFT-Plus was used routinely
