Morning collection (7 a.m. to 10 a.m.) is preferred.
Lavender (K2EDTA) or Pink (K2EDTA). Collection tube must be siliconized glass or plastic.
Separate from cells ASAP or within 2 hours of collection. Transfer 1 mL plasma to an ARUP Standard Transport Tube and freeze immediately. (Min: 0.5 mL)
CRITICAL FROZEN. Separate specimens must be submitted when multiple tests are ordered.
Serum, heparinized plasma, tissue or urine. Grossly hemolyzed specimens.
After separation from cells: Ambient: 3 hours; Refrigerated: 4 hours; Frozen: 1 month (No freeze/thaw cycles.)

7.2 - 63.3 pg/mL (a.m. draws)
Reference interval based on samples collected between 7 a.m. and 10 a.m. No reference intervals established for p.m. collections. Pediatric reference values are the same as adults (Acta Paediatr Scand 1981;70:341-345). This assay measures intact ACTH 1-39; some types of synthetic ACTH and ACTH fragments are not detected by this assay.
No reference intervals established for p.m. collections.
