provocation test

neutralisation test

Pseudomedicine
A test of uncertain validity used by clinical ecologists (practitioners of so-called environmental medicine) to identify various conditions, in particular, environmental disease. The neutralisation test consists of either subcutaneous injection or sublingual placement of the allegedly offending substances (e.g., formaldehye, toluene), and evaluating reactions thereto; the substances are then “neutralised” with lower doses of the same substances. Some clinical ecologists diagnose illness and identify noxious substances by crystals, pendulums, galvanometers, and other devices of questionable diagnostic efficacy.

provocation test

Medtalk
1. Any of a number of tests used to deliberately induce a suspected pathologic derangement–eg, provocation of ↑ intraocular pressure by ingestion of excess water.
2. Neutralization, see there Orthopedics Any of a number of tests designed to reproduce the pain, instability or disability associated with a particular joint injury. See Apprehension test, Fulcrum test, Relocation test, Shoulder instability. Cf Laxity test.

provocation test

(prŏv″ă-kā′shŭn)
A diagnostic test in which drugs, chemicals, allergens, or physical forces are systematically administered to reproduce symptoms, in order to discover the source of a symptom or the tissue origin of a lesion. Provocation tests are used by specialists in several fields of health care, such as: allergists, to determine which of several agents may produce a patient's rhinitis, wheezing, or rash; physical therapists, to identify relationships between a patient's tissue pathology or impairment and his or her functional limitations; and cardiologists and neurologists, who use tilt table provocation tests to diagnose the cause of a patient's loss of consciousness.

First used as a topical antimicrobial agent, CHL is now available in different forms and is present in various settings.[1] CHL has the potential to cause Type I and Type IV hypersensitivity reactions, varying from mild cutaneous reactions to anaphylaxis.[2] An increased recognition of CHL-induced hypersensitivity parallels the increased use of CHL in medical care and the increased awareness of allergy.[3] CHL is an important but easily overlooked allergen, and a provocation test (which serves as the gold standard) is usually difficult to perform.

On the pressure provocation test, the examiner placed his second and third fingers on the ulnar nerve immediately proximal to the cubital tunnel, and exerted pressure for 30 to 60 seconds, with the subject's elbow flexed to about 20[degrees] and the forearm supinated (1,9,10).
For example, in one report, a reported sensitivity of 93% and specificity of 78% were found, only when three or more of six diagnostic tests (distraction provocation test, Gaenslen's test, thigh thrust provocation test, sacral thrust test and compression provocation test) were positive, while other studies have not supported these findings6,7.
Compared to the placebo group, the LPP group had reduced reactivity to a conjunctival provocation test (P < 0.001) and, during the pollen season, a lower rhinoconjunctivitis quality of life global score (P = 0.005).
We report here the case of a 51-year old female psoriatic patient with angioedema (without urticaria) due to oral acitretin, confirmed by a positive oral provocation test. To the best of our knowledge, this is the second description of such an adverse reaction to acitretin.

Pain provocation test using IR at 90[degrees] of hip flexion had excellent specificity (96%, 95% confidence intervals [CIs], 0.77% - 0.998%) but poor sensitivity (50%, 95% CI, 0.26% - 0.74%) for identifying labral tear in participants reporting hip pain.
