A Comprehensive Metabolic Panel (CMP) is a blood test that CLL patients should receive which screens for multiple diseases. It tests for 14 chemicals to evaluate liver and kidney health, blood sugar levels, the acid and base balance of the blood, and the fluid/electrolyte balance. The information gained from the test helps influence treatment decisions for CLL patients and gives insight into the status of the disease.
To prepare for the test, patients are typically asked to fast for a certain period of time before the test, usually 10-12 hours (speak with your doctor about any concerns you may have about fasting). They may also be asked to avoid certain medications or supplements that could interfere with the results of the test.
A phlebotomist or other healthcare provider that is trained in drawing blood samples will perform the test. They'll locate a vein in one of the patient's arms and sterilize the area using an antiseptic solution. A small needle is inserted (the patient may feel a brief sting when the needle is inserted and removed) and a small blood sample is drawn into a test tube. The needle is removed and a bandage is placed onto the test site applying pressure. The test takes less than 5 minutes.
The samples are sent to a lab to be analyzed. Patients can expect their test results back within 1-2 days.
If you have any questions or concerns about the test, please reach out to your CLL specialist.
