| blood circulation time | Determination of the shortest time interval between the injection of a substance in the vein and its arrival at some distant site in sufficient concentration to produce a recognizable end result. It represents approximately the inverse of the average velocity of blood flow between two points. (12 Dec 1998) |

| P-A conduction time | See: atrioventricular conduction. (05 Mar 2000) |
| generation time | <cell biology> Time taken for a cell population to double in numbers and thus equivalent to the average length of the cell cycle. (18 Nov 1997) |
| reaction time | The time from the onset of a stimulus until the organism responds. (12 Dec 1998) |
| real-time ultrasonography | Rapid serial ultrasound images produced using a phased array or scanning transducer; produces a video display of organ motion, such as heart valve or foetal motion. (05 Mar 2000) |
| recognition time | The interval between the application of a stimulus and the recognition of its nature. (05 Mar 2000) |
| partial thromboplastin time | Test of the intrinsic (factors viii, ix, xi, and xii) and common (fibrinogen, prothrombin, factors v and x) pathways of coagulation in which a mixture of plasma and phospholipid platelet substitute (e.g., crude cephalins, soybean phosphatides) is recalcified and the time required for the appearance of fibrin strands measured. Activation may be provided by contact with the glass tube or exposure to activators (e.g., ellagic acid, particulate silicates such as diatomaceous earth or kaolin) before addition of the calcium chloride. It is used as a screening test and to monitor heparin therapy. (12 Dec 1998) |
| relaxation time | Time taken for a system to return to the resting or ground state or a new equilibrium state following perturbation. Often used in context of receptor systems that have a refractory period after responding and then relax to a competent state. Can be used more precisely to mean the time for a system to change from its original equilibrium value to 1/e of this original value. (18 Nov 1997) |
| median time to elimination | <pharmacology> The time it takes one half of a drug to be eliminated from the body. (09 Oct 1997) |
| repetition time | In magnetic resonance imaging, the time between repetitions of the pulse sequence. (05 Mar 2000) |
| rise time | The time required for a pulse or echo to rise from 10% to 90% of its peak amplitude. (05 Mar 2000) |
| P-H conduction time | See: atrioventricular conduction. (05 Mar 2000) |
| running time | The time during which an activity (e.g., chromatography development) occurs. (05 Mar 2000) |
| Russell's viper venom clotting time | A clotting time determination performed on citrated platelet-poor plasma using Russell's viper venom as an activating agent. This allows activation of factor X directly without the need for other coagulation factors and is used to confirm factor X defects. See: Stypven time test. (05 Mar 2000) |
| circulation time | The time taken for the blood to pass through a given circuit of the vascular system, e.g., the pulmonary or systemic circulation, from one arm to another, from arm to tongue, or from arm to lung; it is measured by the injection into an arm vein of a substance, such as sodium dehydrocholate, ether, fluorescein, histamine, or a radium salt, which can be detected when it arrives at another point in the vascular system.
