| McNemar's test | A form of chi-square test for matched paired data. (05 Mar 2000) |
| McPhail test | A test for progesterone and like substances; immature female rabbits are treated with 150 IU of estrone over a period of 6 days; the test material is then given in five daily subcutaneous doses; progestational proliferation of the endometrium is noted and the results estimated according to a scale from 0 to ++++; the amount required to produce an average (++) response is taken as a unit, equivalent to 0.25 mg of progesterone.

| passive cutaneous anaphylaxis test | An animal is injected intradermally with antibody (usually IgE) and subsequently challenged intravenously with a mixture of antigen and Evans blue dye 24-48 hours later. A dark blue area indicates a positive reaction due to the leakage of the dye at the site of antigen-antibody reactions. (05 Mar 2000) |
| patch test | A test of skin sensitiveness: a small piece of paper, tape, or a cup, wet with CO non-irritating diluted test fluid, is applied to skin of the upper back or upper outer arm and after 48 hours the area previously covered is compared with the uncovered surface; an erythematous reaction with vesicles occurs if the substance causes contact allergy. See: photo-patch test. (05 Mar 2000) |
| Reinsch's test | A test for arsenic in which a strip of copper is placed in the suspected fluid, which is then acidulated with hydrochloric acid and boiled; if arsenic is present a gray deposit occurs on the copper, and this deposit on heating is sublimated and deposited as a crystalline layer on a piece of glass held above the copper strip.

| Reiter test | A complement-fixation test for syphilis using as antigen material prepared from the Reiter strain of Treponema pallidum; the test has been largely replaced in laboratory medicine by the fluorescent treponemal antibody-absorption (FTA-ABS) test. (05 Mar 2000) |
| Patrick's test | A test to determine the presence or absence of sacroiliac disease; with the patient supine, the hip and knee are flexed and the external malleolus is placed above the patella of the opposite leg; this can ordinarily be done without pain, but, on depressing the knee, pain is promptly elicited in sacroiliac disease.

| Paul-Bunnell test | Test for detection of heterophil antibodies in infectious mononucleosis. See: Forssman antigen. (05 Mar 2000) |
| Paul's test | Pus is rubbed into a scarification on a rabbit's eye; if the pus is from a variolous or vaccinal pustule a condition of epitheliosis develops in from 36 to 48 hours; the sputum of a smallpox patient is said to cause the same reaction. Synonym: Paul's test. (05 Mar 2000) |
| visual field test | <ophthalmology> A test which measures the extent of visual field loss. This test may be performed by a number of methods including confrontation, tangent screen exam and automated perimetry. Diseases that affect visual field include stroke, diabetes, hypertension, multiple sclerosis, glaucoma, hyperthyroidism, Jacob-Creutzfeldt disease and optic glioma. (27 Sep 1997) |
| glove juice test | <investigation> A test of how effective a particular antimicrobial surgical hand scrub is at disinfecting. (09 Oct 1997) |
| vitality test | A group of thermal and electrical test's used to aid in assessment of dental pulp health. Synonym: pulp test. (05 Mar 2000) |
| PBI test | A formerly used test of thyroid function in which serum protein-bound iodine is measured to provide an estimate of hormone bound to protein in peripheral blood. Synonym: PBI test. (05 Mar 2000) |
| PCR test | <investigation> A very sensitive test that measures the presence or amount of RNA or DNA of a specific organism or virus (for example: HIV or CMV) in the blood or tissue. PCR tests such as HoffmannLa Roche's HIV RT PCR are being used to gauge HIV disease progression and the effect of particular treatments on HIV infection. (09 Oct 1997) |
