The CMP is used as a broad screening tool to evaluate organ function and to check for conditions such as diabetes, liver disease, and kidney disease. The CMP may also be ordered to monitor known conditions, such as hypertension, and to monitor patients taking specific medications for any kidney or liver-related side effects. If your doctor is interested in following two or more individual CMP components, he may order the entire CMP because it offers more information. The CMP is routinely ordered as part of a blood work-up for a medical exam or yearly physical. Although it may be performed on a random basis, the CMP sample is usually collected after a 10 to 12 hour fast (no food or liquids other than water). While the individual tests are sensitive, they do not usually tell your doctor specifically what is wrong. Abnormal test results or groups of test results are usually followed-up with other specific tests to confirm or rule out a suspected diagnosis.
