The CD8+ T cells normally participate in the host (patients) defense to MTB by producing interferon-gamma and other factors which activate macrophages to suppress growth of MTB in the patient, kill infected cells, or directly lyse intracellular MTB. For safety reasons, this is best performed by removing the syringe needle, ensuring appropriate safety procedures, removing the caps from the 4 QFT - Plus Blood Collection Tubes and adding 1 mL of blood to each (to the black mark on the side of the tube label which indicates the validated range of 0.8 - 1.2 mL).
