D factor
| diagnostic audiometry | Measurement of hearing threshold levels to determine the nature and degree of hearing loss (e.g., conductive, sensorineural, or mixed). (05 Mar 2000) |
|---|---|
| diagnostic cast | A positive replica of the form of the teeth and tissues made from an impression. (05 Mar 2000) |
| diagnostic diphtheria toxin | Corynebacterium diphtheriae toxin diluted so that the inoculated dose (0.1 or 0.2 ml) will contain 1/50 th of guinea pig minimal lethal dose. See: Schick test. Synonym: diagnostic diphtheria toxin. (05 Mar 2000) |
| diagnostic equipment | Nonexpendable items used in examinination. (12 Dec 1998) |
| diagnostic errors | Incorrect diagnoses after clinical examination or technical diagnostic procedures. (12 Dec 1998) |
| diagnostic imaging | Any visual display of structural or functional patterns of organs or tissues for diagnostic evaluation. It includes measuring physiologic and metabolic responses to physical and chemical stimuli, as well as ultramicroscopy. (12 Dec 1998) |
| diagnostic sensitivity | The probability (P) that, given the presence of disease (D), an abnormal test result (T) indicates the presence of disease; i.e., P(T/D). See: clinical sensitivity. (05 Mar 2000) |
| diagnostic services | Organised services for the purpose of providing diagnosis to promote and maintain health. (12 Dec 1998) |
| diagnostic specificity | The probability (P) that, given the absence of disease (D), a normal test result (T) excludes disease; i.e., P(T/D). (05 Mar 2000) |
| diagnostic tests, routine | Diagnostic procedures, such as laboratory tests and X-rays, routinely performed on all individuals or specified categories of individuals in a specified situation, e.g., patients being admitted to the hospital. These include routine tests administered to neonates. (12 Dec 1998) |
| diagnostic ultrasound | The use of ultrasound to obtain images for medical diagnostic purposes, employing frequencies ranging from 1.6 to about 10 MHz. (05 Mar 2000) |
| bacterial typing techniques | Procedures for identifying types and strains of bacteria. The most frequently employed typing systems are bacteriophage typing and serotyping as well as bacteriocin typing and biotyping. (12 Dec 1998) |
| behavioural techniques | <psychiatry> A coping strategy in which patients are taught to monitor and evaluate their own behaviour and to modify their reactions to pain. (16 Dec 1997) |
| genetic techniques | Chromosomal, biochemical, intracellular, and other methods used in the study of genetics. (12 Dec 1998) |
| patch-clamp techniques | An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.
