Why This Test Is Done

Your doctor may order this test if you have symptoms like chest pain, shortness of breath, fatigue, or signs of inflammation. It might also be used as part of routine screening or to check for conditions like heart disease, kidney problems, or infections.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if it involves a blood draw. Avoid strenuous activity or certain medications for a few days if instructed.

What the Test Results Mean

Results can vary widely depending on the substance measured. High levels may signal conditions like heart damage, infection, or inflammation, while low levels might indicate deficiencies or other health concerns. Your doctor will interpret results in the context of your symptoms and medical history.

Common Conditions Monitored
