A modification of the leukocyte adherence inhibition method is described which utilizes 51Cr-labeled blood mononuclear cells placed in microwells. The test is reproducible, objective, employs approximately 2,000 cells per well, and allows multiple replicates of several antigens. With the two antigens tested, SK-SD and PPD, both increases and decreases of leukocyte adherence are observed. Serum proteins are important in the medium and inactivated AB serum gave the best results. A good correlation was observed between this leukocyte adherence test and positivity of skin testing,

D007957	Leukocyte Adherence Inhibition Test	Test for cell-mediated antitumor immunity and related serum blocking factors based on the finding that leukocytes from cancer patients, but not from controls, when mixed in vitro with antigenic extracts of tumors of the same histological type, undergo a diminution in their normal adherence to glass surfaces. Sera from tumor-bearing patients block the LAI reaction of their own leukocytes or those of other patients with the same type of tumor.	LAI Test,LAI Tests,Test, LAI,Tests, LAI

D012882	Skin Tests	Epicutaneous or intradermal application of a sensitizer for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity.	Skin Test,Test, Skin,Tests, Skin
D013299	Streptodornase and Streptokinase	A mixture of the enzymes (streptokinase and streptodornase) produced by hemolytic streptococci. It is used topically on surface lesions and by instillation in closed body cavities to remove clotted blood or fibrinous or purulent accumulations. It is also used as a skin test antigen in evaluating generalized cell-mediated immunodeficiency. (Dorland, 27th ed) EC 3.-.	Varidase,Streptokinase and Streptodornase
D014373	Tuberculin	A protein extracted from boiled culture of tubercle bacilli (MYCOBACTERIUM TUBERCULOSIS). It is used in the tuberculin skin test (TUBERCULIN TEST) for the diagnosis of tuberculosis infection in asymptomatic persons.
