Comprehensive Metabolic Panel (CMP) Online Testing

A Comprehensive Metabolic Panel (CMP) is a blood test that measures several substances to assess your body's metabolism, electrolyte balance, and organ function. It is often ordered during routine checkups or to monitor chronic conditions like diabetes, kidney disease, or liver disease.

What it measures

Glucose — Sugar level in your blood, used to screen for diabetes.
Electrolytes (sodium, potassium, chloride, bicarbonate) — Minerals that help control fluid balance and heart rhythm.
Kidney markers (BUN, creatinine) — Waste products that show how well your kidneys filter blood.
Liver enzymes (ALT, AST, ALP, bilirubin) — Proteins and substances that indicate liver health.
Total protein and albumin — Proteins that reflect nutrition and liver or kidney function.
Calcium — Mineral important for bones, muscles, and nerves.

Who it is for

A CMP is typically ordered by a primary care clinician as part of a routine annual exam or to monitor ongoing conditions such as high blood pressure, diabetes, or kidney disease.

Preparation

Fasting for 8–12 hours is often recommended, especially if glucose is being checked, but follow your clinician's instructions. Some labs allow non-fasting testing; no special preparation may be needed if your clinician says so.

Results and what they mean

Results are reported as numbers with reference ranges, and your clinician interprets them in the context of your health history. A single abnormal value does not necessarily mean a problem. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
