| colony count, microbial | Enumeration by direct count of viable, isolated bacterial or fungal cells or spores capable of growth on solid culture media. Each colony (i.e., microbial colony-forming unit) represents the progeny of a single cell in the original inoculum. The method is used routinely by environmental microbiologists for quantifying organisms in air, food, and water; by clinicians for measuring patients' microbial load; and in antimicrobial drug testing.

| white blood cell count | <haematology> A laboratory test which measures the number of white blood cells per cubic millimetre of blood. Normal white blood cell counts are variable with age and sex. Normal adult range is 4, 500 to 11,000 cells per cubic millimetre of blood. Slightly higher counts are seen in children. Elevated counts can be seen in cases of inflammation and infection. (13 Nov 1997) |
| complete blood count | <haematology, investigation> The number of red blood cells, white blood cells and platelets are present in the patients sample of blood is determined. most common test done on the blood. Acronym: CBC Synonym: full blood count. (16 Mar 1998) |
| platelet count | <haematology> The number of platelets per cubic millimetre of blood. The normal range is 150,000-400,000 platelets per cubic mm. Platelet counts under 10,000 per cubic millimetre place the patient at risk for spontaneous haemorrhage. Platelets are produced in the bone marrow in increased quantities in response to stress.

| count | 1. A reckoning, enumeration, or accounting. 2. To enumerate or score. (05 Mar 2000) |
| count density | The number of counted events recorded in scintigraphy per square centimeter or per square inch of imaged area. Synonym: count density. (05 Mar 2000) |
| Schilling's blood count | A method of counting blood in which the polymorphonuclear neutrophils are separated into four groups according to the number and arrangement of the nuclear masses in these cells. Synonym: Schilling's index. (05 Mar 2000) |
| sperm count | The number of sperm in the ejaculate (when given as the number of sperm per millileter it is more accurately known as the sperm concentration or sperm density). (09 Oct 1997) |
| total cell count | Number of cells in a given area or volume. (05 Mar 2000) |
| eosinophil count | A measurement (cells per microlitre) of the number of eosinophils in a blood specimen. This measurement, also called the absolute eosinophil count, is useful in the evaluation of autoimmune disease, allergies, eczema, leukaemia, asthma and hay fever. Normal absolute eosinophil counts are less than 350 cells/mcl (microlitre). (27 Sep 1997) |
| epidermal ridge count | An index of the frequency of sweat pores on the fingertips by enumeration along a set of arbitrarily defined lines; a classic example of a galtonian trait determined almost exclusively by genetic factors. (05 Mar 2000) |
| erythrocyte count | A count of the number of red blood cells per unit volume in a sample of venous blood. (12 Dec 1998) |
| filament-nonfilament count | A differential count of the number of neutrophils showing nuclear division and those showing no such division. (05 Mar 2000) |
| Full Blood Count | <haematology, investigation> The determination of the proper number of red blood cells, white blood cells and platelets are present in the patients blood. Acronym: FBC (16 Dec 1997) |
| leukocyte count | A white blood cell (WBC) count. (12 Dec 1998) |
