count (kount) a numerical computation or indication.

Addis count  determining the number of erythrocytes, leukocytes, epithelial cells, casts, and protein content in an aliquot of a 12-hour urine specimen.

blood count , blood cell count determining the number of formed elements in a cubic millimeter of blood; it may be a complete blood count or it may measure just one of the formed elements.

complete blood count  a series of tests of the peripheral blood, including the hematocrit, the amount of hemoglobin, and counts of each type of formed element.

differential leukocyte count  a count on a stained blood smear of the proportion of different types of leukocytes (or other cells), expressed in percentages.

platelet count  determination of the total number of platelets per cubic millimeter of blood; the direct platelet c. simply counts the cells using a microscope, and the indirect platelet c. determines the ratio of platelets to erythrocytes on a peripheral blood smear and computes the number of platelets from the erythrocyte count.
