| lactate level | A test that measures the amount of lactic acid in the blood. Lactic acid is an intermediate product of carbohydrate metabolism and is derived mainly from muscle cells and red blood cells. Exercise will normally raise lactic acid levels. Conditions of oxygen deprivation (for example shock, heart failure, lung disease) will trigger anaerobic metabolism within muscle tissue resulting in lactic acid build up in the tissues. Normal lactic acid levels are 4.5 to 19.8 mg/dl. (27 Sep 1997) |
| lactic acid level | <investigation> A test that measures the amount of lactic acid in the blood. (25 Jun 1999) |
| free calcium level | <biochemistry> The ionised calcium represents the calcium (Ca++) that is the metabolically active calcium. Normal values for ionised calcium in the bloodstream should be 4.4 to 5.3 mg/dl for adults and 4.4 to 6.0 mg/dl for children. Elevations may be seen in hyperparathyroidism, metastatic bone tumour, milk-alkali syndrome, multiple myeloma, Paget's disease, sarcoidosis, PTH-secreting tumours (paraneoplastic syndrome) and vitamin D intoxication. Lower than normal values may be seen in hypoparathyroidism, malabsorption, osteomalacia, pancreatitis, renal failure, rickets and vitamin D deficiency. (27 Sep 1997) |
| level of aspiration | <psychology> The degree or quality of performance (exhibited in a testing situation) which an individual desires to attain or feels he can achieve. (05 Mar 2000) |

| traumatic amnesia | The loss or disturbance of memory following an insult or injury to the brain of the type that accompanies a head injury, or excessive use of alcohol, or following the cessation of alcohol ingestion or other psychoactive drugs; or loss or disturbance of memory of the type seen in hysteria and other forms of dissociative disorders. (05 Mar 2000) |
| traumatic anaemia | An acute anaemia caused by fairly sudden and rapid loss of blood, as by traumatic laceration of a relatively large vessel, erosion of an artery in a duodenal ulcer, haemorrhage in an ectopic pregnancy, or the result of such diseases as haemophilia and acute leukaemia. Synonym: traumatic anaemia. (05 Mar 2000) |
| traumatic anaesthesia | Loss of sensation resulting from nerve injury. (05 Mar 2000) |
| traumatic aneurysm | An aneurysm resulting from physical damage to the wall of an artery; usually a false aneurysm or arteriovenous aneurysm. (05 Mar 2000) |
| traumatic asphyxia | Cyanotic asphyxia due to trauma; the extravasation of blood into the skin and conjunctivae, produced by a sudden mechanical increase in venous pressure, analogous to the Rumpel-Leede test; it is common in those who have been hanged, and is seen occasionally in crush injuries. Synonym: pressure stasis. (05 Mar 2000) |
