| Chick-Martin test | A method of testing the in vitro efficiency of a bactericidal agent; a standard culture of Salmonella typhi which has been added to a fixed amount of sterilised faeces or yeast is tested for a fixed period (30 minutes), against various concentrations of phenol solution and various concentrations of the disinfectant; the result is expressed as a ratio: the phenol coefficient, which is the highest dilution of the disinfectant under test at which the bacteria are killed, divided by the highest dilution of phenol which sterilises the solution in the same length of time.

| chi-square test | A statistical method of assessing the significance of a difference, as when the data from two or more samples is represented by a discrete number such as the numbers of females and males attending each of two colleges. Synonym: x2 test. (05 Mar 2000) |
| metabisulfite test | A test for sickle cell haemoglobin (Hb S); deoxygenation of cells containing Hb S is enhanced by addition of sodium metabisulfite to the blood, causing sickling visible on a slide; certain other abnormal haemoglobins (Hb CHarlem and Hb I) also sickle in this test.

| Rimini's test | A test for formaldehyde in urine, milk, and other fluids, by the use of dilute solution of phenylhydrazine hydrochloride, sodium nitroprusside, and sodium hydroxide. (05 Mar 2000) |
| ring precipitin test | A precipitin test in which antigen solution is carefully layered over antibody solution in a tube; as diffusion proceeds, a disk of precipitate forms where the antibody ratio is optimal. Synonym: ring test. (05 Mar 2000) |

| personality test | Any of the category of psychological test's designed to test the characteristics of the personality, emotional status, mental disorder, etc., in contrast to an intelligence test. (05 Mar 2000) |
| group test | In psychology, a test designed to be administered to more than one individual at a time; e.g., scholastic achievement test, medical college admissions test. (05 Mar 2000) |
| Rinne's test | As a positive test: a vibrating tuning fork is held in contact with the skull (usually the mastoid process) until the sound is lost, its prongs are then brought close to the auditory orifice when, if the hearing is normal, a faint sound will again be heard, as a negative test: a vibrating tuning fork is heard longer and louder when in contact with the skull than when held near the auditory orifice, indicating some disorder of the sound conducting apparatus.

| Perthes' test | A test for patency of deep femoral vein; with the patient standing, a tourniquet is applied above the knee; after walking, if deep circulation is competent, the superficial varicosities remain unchanged and legs become painful. (05 Mar 2000) |
| growth hormone stimulation test | <investigation> A test which measures the level of human growth hormone in response to the administration of the amino acid arginine. This test measures the ability of the pituitary gland to secrete growth hormone. Normal values in children are: 48 ng/ml. Normal values in men are 10 ng/ml. Normal values in women are 15 ng/ml. This test is used to evaluate infants with growth retardation. It may also be part of an evaluation for a pituitary tumour. Failure of arginine to raise growth hormone levels may indicate hypopituitarism or dwarfism. (27 Sep 1997) |
| growth hormone suppression test | <investigation> A test to determine if growth hormone is suppressed by hyperglycaemia. Growth hormone blood levels are determined sequentially after ingestion of a glucose-rich meal. If growth hormone levels remain elevated (after the glucose is given) then acromegaly or gigantism is suspected. (27 Sep 1997) |
