Why This Test Might Be Ordered

Your doctor may recommend this test if they suspect conditions like immune system disorders, protein-related diseases, or to monitor treatment progress for conditions affecting protein levels in the blood.

What to Expect Before the Test

No special preparation is typically needed unless instructed by your doctor. You may fast before the test if it involves blood draw, but always follow your provider’s specific instructions.

What Happens During the Test

A healthcare professional will draw blood from a vein in your arm. The sample is then sent to a lab for analysis to measure the protein concentration.

What the Results Mean

Results will show the concentration of the protein in your blood. Abnormal levels may signal underlying health issues, such as inflammation, kidney disease, or genetic disorders.

Reference range

NCBI: ACTH 10-60 pg/mLN/A

Specimen: serum

Typically collected in the morning (8-10 AM). Inform your provider if taking steroid medications.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a normal range mean for this test?
There is no single ‘normal’ range for this specific protein test since the reference range can vary based on the protein measured and lab methods. Your results will be compared to your own baseline or lab-specific standards to determine if levels are within expected limits.
How often should I get this test?
Your doctor will determine the frequency of testing based on your medical history, symptoms, and treatment plan. Regular monitoring may be needed if you have a condition that affects protein levels, such as kidney disease or an autoimmune disorder.
Can diet or lifestyle affect this test result?
Yes, certain foods, medications, or lifestyle factors (like dehydration or exercise) may influence protein levels. Avoiding certain foods or medications for a few days before testing can help ensure more accurate results.
