Guides for kidney testing

What is a comprehensive metabolic panel testing for?

A comprehensive metabolic panel (CMP) measures 14 substances in one blood sample to give a broad picture of kidney function, liver function, blood sugar, protein levels and electrolyte balance. It is one of the most commonly ordered blood tests in routine care, and it usually requires fasting because it includes glucose.

What Are the 5 Common Baseline Lab Tests?

Five blood tests are frequently described as a general "baseline" health check: a complete blood count (CBC), a comprehensive metabolic panel (CMP), a lipid panel, hemoglobin A1c, and a thyroid-stimulating hormone (TSH) test. Together they survey blood cells, organ chemistry, cholesterol, blood sugar, and thyroid function. This article explains what each one measures. It is educational and not a recommendation about your own care.

How to Order Your Own Blood Work Without a Doctor

You can order most routine blood tests online without seeing a doctor first. The ordering service has a physician sign the lab order for you, you have blood drawn at a Quest or LabCorp location, and the results come straight to you. New York, New Jersey and Rhode Island are the states these services most often exclude.
