Corticosterone (Endocrine Sciences)
Use
Corticosterone is a steroid hormone produced by the adrenal gland, playing a crucial role in energy regulation and the stress response. It is commonly measured to assess adrenal function and diagnose conditions such as Cushing's syndrome or Addison's disease.
Special Instructions
Ensure that serum is separated from cells within one hour of collection to maintain sample integrity. Multiple tests on frozen samples require separate specimens to avoid delays.
Limitations
This test may require confirmatory or reflex tests dependent on initial findings, potentially extending the turnaround time. Sample handling errors such as inadequate separation of serum from cells may affect the accuracy of results.
