    Inhibition of buffy layer peripheral leucocyte migration by tuberculin purified protein derivative (PPD) from micro-capillaries mounted in small tissue culture chambers correlates in all cases with a positive Mantoux test. This quick and reproducible test of cellular hypersensitivity in man requires only 5-15 ml of blood and is applicable for study in children and in clinical situations where repeated monitoring of cellular immunity may be required.
