Serum or Plasma Substance Concentration for Omnipresent Hormone/Inflammatory Marker (e.g., Cortisol, Adrenocorticotropic Hormone, or other peptide/protein)

What This Test Measures

This test detects a particular substance in your blood, often used to assess hormonal function, stress responses, or markers of inflammation. The substance could be a hormone (like cortisol or ACTH), a protein, or another biologically active compound. The method used may involve immunoassay or another sensitive detection technique to ensure accuracy.

Why It’s Ordered

Your healthcare provider may recommend this test to evaluate conditions such as adrenal gland function, stress responses, or chronic inflammation. It could also be part of a broader evaluation for hormonal disorders, immune system issues, or metabolic health.

Sample Collection and Preparation

Blood is drawn from a vein, typically in your arm. The sample is collected in a tube that separates serum (liquid part after clotting) or plasma (liquid part before clotting). This test does not require fasting unless specified by your provider.

Test Results and Interpretation

Results are compared to a reference range provided by your lab. While exact values vary by test, higher or lower levels than expected may signal potential health concerns that need further investigation.
