What this test is
The CMP is a group of tests that measure several substances in the blood, including glucose, electrolytes, and markers of kidney and liver function. It is often used as a general health screening tool or to monitor ongoing conditions.
What it measures
- Glucose — reflects blood sugar levels
- Calcium — reflects calcium balance
- Sodium, potassium, chloride, and bicarbonate — reflect electrolyte and fluid balance
- Blood urea nitrogen (BUN) and creatinine — reflect kidney function
- Albumin and total protein — reflect nutritional status and liver function
- Liver enzymes (ALP, ALT, AST) — reflect liver health
- Bilirubin — reflects liver and bile duct function
What the test involves
The test requires a standard blood draw, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order a CMP as part of a routine checkup, to screen for conditions such as diabetes or kidney disease, or to monitor the effects of certain medications. It can also help evaluate symptoms like fatigue, confusion, or swelling.
Preparation
Preparation instructions can vary depending on the laboratory and the reason for testing. Always follow the specific instructions provided by the collection lab, which may include fasting for several hours before the draw.
How results are reported
Results are typically reported as numerical values for each component, along with a reference range. Reference ranges can differ between laboratories, so your results should be interpreted in the context of the lab that performed the test.
