| total dissolved solids | A measure of inorganic and organic materials dissolved in water (passing through a 0.45 micron filter), expressed as mg/l FR. Sometimes considered similar to conductivity as an indicator of potential production in habitat quality indices. (09 Oct 1997) |
|---|---|
| total elasticity of muscle | The combined effect of physical and physiologic elasticity of muscle. (05 Mar 2000) |
| total end-diastolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in diastole. (05 Mar 2000) |
| total end-systolic diameter | Cross sectional diameter of the left ventricle including the septum and posterior wall thicknesses in systole. (05 Mar 2000) |
| total energy | The sum of kinetic and potential energy's. (05 Mar 2000) |
| total facial index | Length is measured from the nasion to the mental tubercle: (nasimental length × 100)/bizygomatic width. (05 Mar 2000) |
| total fertility rate | <epidemiology> The number of children an average women would have assuming that she lives her full reproductive lifetime. (05 Dec 1998) |
| total haematuria | Uniform mixing of blood in the entire voided urine, commonly indicating an upper or mid-urinary tract source of bleeding. (05 Mar 2000) |
| total hyperopia | That which can be determined after complete paralysis of accommodation by means of a cycloplegic. (05 Mar 2000) |
| total hysterectomy | Complete surgical removal of the uterus and cervix. Also called a complete hysterectomy. (12 Dec 1998) |
| total iron binding capacity | <biochemistry, haematology> A test that measures indirectly the transferrin level in the bloodstream. Transferrin is a protein that carries iron in the body. Normal values are 240 to 450 mcg/dl. This test is used to evaluate anaemia. Greater than normal total iron binding capacity can be seen in: iron deficiency anaemia, late pregnancy and polycythaemia vera. Lower than normal total iron binding capacity can be seen in cirrhosis, sickle cell anaemia, hypoproteinaemia, pernicious anaemia and haemolytic anaemia. The use of birth control pills can lead to increased total iron binding capacity measurements. Acronym: TIBC (12 Jan 1998) |
| total joint arthroplasty | Arthroplasty in which both joint surfaces are replaced with artificial materials, usually metal and high-density plastic. (05 Mar 2000) |
| total keratoplasty | Corneal transplant in which the entire cornea is removed and replaced. (05 Mar 2000) |
| total knee joint replacement | Surgery involving the replacement of the knee joint with artificial components which reestablishes normal joint function. Indicated in cases of severe knee fracture or degenerative arthritis (DJD) unresponsive to medical therapy. (27 Sep 1997) |
| total lung capacity | The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: vital capacity plus residual volume; inspiratory capacity plus functional residual capacity; tidal volume plus inspiratory reserve volume plus functional residual capacity; tidal volume plus inspiratory reserve volume plus expiratory reserve volume plus residual volume.
