Seasonal Variability of the Methacholine Challenge Test

Journal of Asthma, 2009
Since the intensity of some variables that influence bronchial hyper-responsiveness (BHR) varies across different seasons of the year, the percentage of positive metacholine challenge test (MCT) is theoretically subjected to seasonal variation. This study has looked at the seasonal variability of MCT among young adults with suspected asthma.The number ...

The Abbreviated Methacholine Challenge Test is Safe for Children

The Journal of Pediatrics
To evaluate the safety of an abbreviated methacholine challenge test (MCT) protocol in children.This prospective, observational study enrolled children aged 6 through 18 years referred for the MCT. The abbreviated protocol was initiated with a methacholine dose of 0.03 mg/ml and escalated in fourfold increments, unless the forced expiratory volume at 1

Methacholine challenge test.

Archives of internal medicine, 1984
Methacholine challenge has been proposed as a diagnostic test in situations where clinical asthma is suspected but reversible airway obstruction cannot be demonstrated spirometrically. Methacholine challenge was used in 14 patients with suspected asthma and five normal controls.

Clinical Use of Methacholine Bronchial Challenge Testing

Southern Medical Journal, 1987
Whereas the research applications have been well established, the clinical utility of bronchial challenge testing is still being defined. In 19 of 22 patients referred for testing (86%), the results of a methacholine challenge test helped to confirm a clinical suspicion of asthma or to suggest that alternative diagnoses should be investigated.
