| tuberculo-opsonic index | The opsonic index calculated in relation to tuberculous infection, with an actively growing culture of Mycobacterium tuberculosis or the strain of tubercle bacillus from the patient being used in the test. (05 Mar 2000) |

| facial index | Relation of the length of the face to its maximal width between the zygomatic prominences; to get (05 Mar 2000) |
| karyopyknotic index | An index used to monitor the hormonal status of the patient as reflected by exfoliated vaginal cells and their morphology; an expression of the percentage of intermediate and superficial cells from squamous cells of vaginal epithelium which have pyknotic nuclei. (05 Mar 2000) |
| zygomaticoauricular index | The ratio between the zygomatic and the auricular diameters of the skull or head. (05 Mar 2000) |
| uricolytic index | <biochemistry> The percentage of uric acid oxidised to allantoin before being secreted. (05 Mar 2000) |
| Flower's dental index | Relation of the dental length (distance from the mesial surface of the first premolar to the distal surface of the third molar) to the basinasal (basion to nasion) length: (dental length ×100)/basinasal length, a system of numbers for indicating comparative size of the teeth. Synonym: Flower's dental index. (05 Mar 2000) |
| freedle index | An index of the quality of spawning gravel obtained by dividing geometric mean diameter of particle size by the sorting coefficient. (09 Oct 1997) |
| free thyroxine index | An arbitrary value obtained by multiplying the triiodothyronine uptake by the serum thyroxine concentration; it largely corrects for variations in thyroid-bound globulin concentration by providing a clinically valid estimate of the physiologically active free thyroxine; direct assay or laboratory measurement of free serum thyroxine yields a more accurate value. (05 Mar 2000) |
| length-breadth index | The ratio of the maximal breadth to the maximal length of the head, obtained by the formula: (breadth × 100)/length. Synonym: length-breadth index. (05 Mar 2000) |
| length-height index | The relation of the height to the length of the skull: (height × 100)/length. Synonym: height-length index, length-height index, transversovertical index. (05 Mar 2000) |
| leukopenic index | A significant decrease in the white blood count after ingestion of food to which a patient is hypersensitive, a count made during the normal fasting state being used as the basis for evaluation of the postprandial count. (05 Mar 2000) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used. (05 Mar 2000) |
| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
