| Perls' test | A test for haemosiderin, utilizing Perls' Prussian blue stain. (05 Mar 2000) |
| 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) |

| 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. (05 Mar 2000) |
| 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) |
| guaiac test | Glacial acetic acid, gum guaiac solution, and hydrogen peroxide are added to an aqueous suspension of the suspected stain; if occult blood or blood pigment is present, a blue colour develops. Synonym: guaiac test, Schonbein's test, van Deen's test. (05 Mar 2000) |
| Gunzberg's test | A test for hydrochloric acid utilizing phloroglucin vanillin (Gunzberg's reagent), with which a bright red colour is produced in the presence of the acid. (05 Mar 2000) |
| Guthrie test | <investigation> Bacterial inhibition assay for direct measurement of serum phenylalanine; in widespread use for detection of phenylketonuria in the newborn. (05 Mar 2000) |
| Gutzeit's test | A test for arsenic; a piece of zinc and a little sulfuric acid are added to the suspected liquid which is then boiled; a bit of filter paper with a silver nitrate solution is held in the vapor and will turn yellow if arsenic is present. (05 Mar 2000) |
