This Quest Diagnostics salivary cortisol test measures free cortisol levels using liquid chromatography/mass spectrometry (LC/MS), a highly specific analytical method that minimizes cross-reactivity with cortisol metabolites. Collected non-invasively via saliva, the test reflects unbound, biologically active cortisol — making it a practical option for those monitoring adrenal function, HPA axis activity, or circadian cortisol patterns.
Why It's Worth Considering: LC/MS methodology offers greater analytical precision than standard immunoassay-based saliva tests, particularly useful when accurate quantification matters for clinical decision-making.
