Cortisol, LC/MS, Saliva 19897
Saliva · Fasting not stated · Turnaround Set up: Mon, Wed, Fri
Method and collection
Method
Chromatography/Mass Spectrometry
Collection
a. Saliva collection should be done at the earliest 60 minutes after brushing teeth, a meal (liquid/solid food intake) or oral intake of medication and 10 minutes after rinsing the mouth with water in order to avoid contamination of the saliva by interfering substances. b. Remove the swab from the Salivette. c. Place the swab in the mouth, e.g. in your cheek, where it should remain for 2 minutes without chewing. If an extremely small amount of saliva is produced, leave the swab in the mouth for longer. d. Return the swab with the absorbed saliva to the Salivette. e. Replace the stopper. f. Refrigerate the Salivette immediately.

Verify these ranges and sources

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
