Differential Leucocyte Count: From 1 Different Sources
(differential blood count) a determination of the proportions of the different kinds of white cells (leucocytes) present in a sample of blood. Usually 100 white cells are counted and classified under the microscope or by electronic apparatus, so that the results can readily be expressed as percentages of the total number of leucocytes and the absolute numbers per litre of blood. The information often aids diagnosis of disease.

An immunological assessment used to monitor for signs of organ rejection after transplantation; it is also used to check the progress of treatment in patients with HIV (see AIDS/ HIV). The count measures the ratio of helper-induced T-lymphocytes to cytotoxic-suppressor lymphocytes. (See LYMPHOCYTE; IMMUNOLOGY.)... cd4/cd8 count

(EECP) an experimental treatment for patients with intractable angina. Specially designed inflatable trousers are inflated rhythmically in time with ventricular *diastole. Theoretically this imparts additional energy to the circulating blood volume when the heart is relaxed, and this may improve blood flow down severely narrowed coronary arteries. It is also claimed to have beneficial effects on blood flow to other organs. Despite promising clinical trials, this technique has not been widely adopted.... enhanced external counterpulsation

(OTC drug) a drug that may be purchased directly from a pharmacist without a doctor’s prescription. Current government policy is to extend the range of OTC drugs: a number have already been derestricted (e.g. ibuprofen, ranitidine) and this trend is increasing, which will place an additional advisory responsibility on pharmacists.... over-the-counter drug
