| 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) |
| differential white blood count | An estimate of the percentage of white blood cell types which make up the total white blood cell count. (05 Mar 2000) |
| 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) |
| low platelet count | <haematology> An abnormally low platelet count. Normal platelet counts are 150,000-400,000 per cubic millimetre. Those with low platelet counts may exhibit haematuria, haematemesis, easy bruising, bleeding gums, melena (blood in stools), prolonged menses or nosebleeds. Spontaneous intracranial haemorrhage can occur with platelet counts of 10-15,000 (or less). (27 Sep 1997) |
| lymphocyte count | A count of the number of lymphocytes in the blood. (12 Dec 1998) |
