The macrophage electrophoretic mobility (MEM) test--an investigation of its value as a routine laboratory test in the detection of malignant disease. 1978

A previous study of the MOD-MEM test showed promising results. We have attempted to repeat the study using a blind coded series of 210 blood samples from normal subjects and patients with either benign or malignant disease. Using standard criteria the false negative rate for cancer patients averaged 43% and the false positive rate for non-cancer patients averaged 34%. The results indicate that the test at the present time, under routine laboratory conditions, is not reliably reproducible and does not have the ability to effectively discriminate between benign and malignant disease. It is suggested that blind coded studies be used more frequently in assessment of tests with cancer detection potential.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
