Cortisol, Salivary
Test Name Cortisol, Salivary
Specimen Type / Requirements Container Type = Salivary Corsitol Kit Minimum Testing Volume = 1mL Saliva
Specimen Handling Collection Instructions: Collection kit can be obtain in outpatient laboratories or in biochemistry. Ensure both samples and requisitions are labeled properly. Laboratory Staff Instructions: Samples received at room temperature (20-25°C) or cooled (2-8°C) should bring to 20-25°C for centrifugation. Stability: Centrifuged saliva sample is stable for 24 hours at 20-25°C, 4 days at 2-8°C and 12 months at -20°C (freeze only once). Transportation: Transport at room temperature ASAP. Place on ice if time of collection to time sample get to lab exceeds 2hrs Sample Rejection Criteria: The centrifuged or uncentrifuged saliva sample is stable for: • 7 days at 20-25°C • 28 days at 2-8°C • 12 months at -20°C (stable up to 3 freeze/thaw cycles)
