Clinical Info:
The CMP or comprehensive metabolic panel is a very commonly ordered laboratory test. This test is a profile with 14 components that includes direct analytes and some ratios and other calculations. The test is designed to determine a patients overall general health status and to screen for; or diagnose a variety of conditions and diseases. Abnormal results in any of the components of this profile may warrant additional testing and investigation.
Additional Information:
The comprehensive metabolic panel (CMP) is used as a broad screening tool to evaluate the health of your patient and to screen for conditions such as diabetes, liver disease, and kidney disease among other possible conditions. The CMP may also be ordered to monitor patients with known conditions, such as high blood pressure (hypertension), and to monitor treatment with specific medications that may affect kidney or liver function and overall chemistry or metabolism.
Sample Collection:
A fasting specimen is requested to obtain a valid fasting glucose. Keep the tube sealed to prevent any shifts in sample carbon dioxide (Co2) levels.
Collect patient samples using standard phlebotomy techniques. Click here for additional collection instructions.
Test Limitations:
Delayed separation of serum/plasma from cells may cause inaccurate results. Prolonged exposure of serum/plasma to blood cells may cause glucose levels to go down and potassium levels to go up.
Specimen Handling Instructions:
Maintain at ambient temperature; or refrigerated if more than 12 hours. Avoid exposure to heat or freezing temperatures.
