Peptide Metabolite Screening in Serum/Plasma (24-hour profile)
This test measures specific small peptide molecules in your blood, which may help assess metabolic function, hormone regulation, or protein breakdown processes over a 24-hour period.
["This test helps evaluate how your body processes peptides, which can inform treatment decisions for conditions like metabolic disorders or endocrine issues."]

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have symptoms or conditions linked to abnormal peptide metabolism, such as unexplained weight changes, fatigue, or hormonal imbalances. It may also be used to monitor certain chronic diseases or after treatment for metabolic disorders.
What to Expect Before the Test
No special preparation is typically needed, but you may be asked to fast for 8–12 hours before the blood draw if your provider specifies it. Wear comfortable clothing and plan to rest during the procedure.
During the Test Process
A healthcare professional will draw blood from a vein in your arm. You may feel a slight pinch, but the process usually takes a few minutes. The blood sample will be sent to a lab for analysis of multiple peptide metabolites.
What the Results Mean
Results will show levels of various peptides, which your provider will interpret in relation to your medical history and symptoms. Elevated or low levels may indicate specific metabolic or endocrine conditions requiring further evaluation.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Peptide metabolites play roles in energy metabolism, hormone signaling, and protein turnover. Abnormal levels may signal conditions like diabetes, thyroid disorders, or kidney function issues. This test can help identify subtle metabolic imbalances that standard tests may miss.
