1.0 mL aprotinin treated EDTA plasma in non-additive transport tube (labeled as AP treated plasma).
Test Description
Endogenous ACTH used for small animal testing.
Note: Endogenous ACTH is extremely labile. Immediately separated and frozen EDTA-plasma without aprotinin may be acceptable but is NOT the preferred sample. Serum or heparinized plasma is not acceptable for endogenous ACTH testing. Call lab to obtain an aprotinin-treated lavender top tube and transfer tube.
