provocation test

An example of a provocation test, performed on an individual, is a skin allergy test.

There was also no relation between the results of the provocation test and the number and nature of symptoms.

Gaenslen test - This pain provocation test applies torsion to the joint.

The visual analog pain scale has been used as a pragmatic reference standard for palpatory pain provocation tests.

Bronchial provocation test (test measuring reaction to the suspected allergen)

Demonstrate provocation test where clients deliberately over-breath - discuss catastrophic misinterpretation of symptoms - breathing exercises.

Two types of pain provocation tests were used: digital pressure (within 5 cm of the midline) and lumbar percussion.

A positive provocation test was documented if upper abdominal pain was present with or without nausea after introduction of duodenal contents.

The DEC provocation test is performed to obtain satisfying numbers of parasites in daytime samples.

The differentiation between these conditions is especially difficult if Zollinger-Ellison patients have a negative secretin provocation test and no obvious tumours shown by computed tomography.

All three patients after vagotomy and pyloroplasty had negative provocation tests and average gastric sodium concentrations were above 100 mmol/l for only 16% of the study.

Class of test: Oral provocation test: Foods are eliminated until symptoms disappear or lessen, then reintroduced until symptoms reappear.

It can be used to measure nasal anatomical landmarks, nasal septum deviation, and nasal airway changes in response to allergen provocation tests.

The relation between DGR and symptoms in patients with pain after gastric surgery was also investigated by a provocation test with the patient's own bile enriched duodenal juice.

Patients with positive bile provocation tests did not show any significant difference in the duration of reflux compared with those with a negative provocation test (79% and 87%).

Symptomatic patients with excessive DGR and a positive provocation test might be expected to benefit from treatment designed either to prevent DGR or to protect the gastric mucosa.

Pain Provocation The two studies differed in procedure location (cervical vs. thoracic & lumbar), reference standard (VAS vs. subjective patient report), provocation test used and population studied.

The Nardi test, also known as the morphine-neostigmine provocation test is a test for dysfunction of the sphincter of Oddi, a valve which divides the biliary tract from the duodenum.

This situation makes it difficult to use basal colonic motility as a basis for comparisons and has led to the development of provocation tests in a controlled environment in an attempt to characterise differences between groups of patients.

Allergen provocation testing - hospital medical staff perform provocation tests by introducing the suspected aero-allergen (pollen, dust mite, animal dander or mould extract) directly into the nose, lung or eye to see if they provoke an allergic reaction.

Conversely, a negative provocation test suggests that the patient's pain is not due to the presence of irritant duodenal juice in the stomach, but could be associated with abnormal motility associated with DGR, or might be due to an unrelated cause.

PROVOCATION TESTS Class of test: Bronchial provocation test: Patient inhales allergen in attempt to induce actual allergic reaction, such as sneezing or asthma.

A provocation test, also called a provocation trial or provocation study, is a form of medical clinical trial whereby participants are exposed to either a substance or "thing" that is claimed to provoke a response, or to a sham substance or device that should provoke no response.
