What This Panel Evaluates
This panel combines three distinct types of testing: a metabolic and organ function panel, a longer-term glycemic marker, and a complete blood count. The Comprehensive Metabolic Panel with eGFR looks at your current glucose level alongside kidney function, liver function, electrolyte balance, and calcium, giving you a snapshot of several body systems at once. Hemoglobin A1c is measured separately and reflects your average blood glucose over roughly the past two to three months, which is different information than a single current glucose reading.
The CBC with Differential and Platelets rounds out the panel by evaluating your red blood cells, white blood cells, and platelets. Together, these components provide complementary but separate types of information. They do not by themselves diagnose diabetes, determine diabetes type, or replace a full medical evaluation.
What's Included in This Panel
Comprehensive Metabolic Panel (CMP-14) with eGFR Blood Test
Glucose
Kidney Profile
- BUN (Blood Urea Nitrogen): A waste product formed when the body breaks down protein, normally removed by the kidneys.
- Creatinine, Serum: A waste product from normal muscle activity that is filtered from the blood by the kidneys.
- BUN/Creatinine Ratio: A calculated value (BUN divided by creatinine) that can suggest conditions like dehydration or intestinal bleeding.
- Estimated Glomerular Filtration Rate (eGFR): A calculated estimate of how effectively the kidneys filter waste from the blood, used to assess kidney function.
Liver Panel
- Protein, Total: The combined amount of albumin and globulin proteins in the blood, which helps assess liver and kidney function and nutritional health.
- Albumin, Serum: A protein produced by the liver that helps maintain fluid balance and transport substances through the blood.
- Globulin, Total: A group of blood proteins involved in immune defense, transporting substances, and other important body functions.
- Albumin/Globulin Ratio: A calculated value (albumin divided by globulin) that, alongside other results, can assist in evaluating liver problems.
- Bilirubin, Total: A yellow pigment produced during the normal breakdown of red blood cells and processed by the liver. Elevated levels can cause jaundice.
- Alkaline Phosphatase: An enzyme found primarily in the liver, bile ducts, and bones that can help identify liver or bone disorders.
- Aspartate Aminotransferase (AST or SGOT): An enzyme found in the liver and other tissues, such as the heart and muscles, that is released into the blood when cells are damaged.
- Alanine Aminotransferase (ALT or SGPT): An enzyme that helps identify liver damage. Abnormal levels may represent liver disease.
Fluids & Electrolytes
- Sodium: One of the major salts in your body fluid, important for water balance and the electrical activity of nerves and muscles.
- Potassium: Helps control the function of your nerves and muscles.
- Chloride: Similar to sodium, it helps maintain your body's electrolyte balance.
- Carbon Dioxide, Total: A measure that primarily reflects bicarbonate in the blood, helping assess the body's acid-base balance.
- Calcium: A mineral essential for developing and maintaining healthy bones and teeth, and for normal muscle, nerve, and blood clotting function.
Hemoglobin A1c
- Hemoglobin A1c: Reflects average blood glucose over the past 2 to 3 months.
Complete Blood Count (CBC) with Differential and Platelets Blood Test
White Blood Cells
Red Blood Cells and Red Cell Indices
- Red Blood Cells (RBC): Carries oxygen and carbon dioxide to and from your cells. Iron deficiency can lower this count.
- Hemoglobin: A compound inside red cells that carries oxygen through your bloodstream and gives blood its red color.
- Hematocrit: The percentage of blood volume made up of red blood cells.
- MCH (Mean Corpuscular Hemoglobin): The average hemoglobin amount within a single red blood cell.
- MCHC (Mean Corpuscular Hemoglobin Concentration): The average hemoglobin concentration percentage within a red blood cell.
- MCV (Mean Corpuscular Volume): The average size of your red blood cells.
- RDW (Red Cell Distribution Width): Measures the variation in volume and size among your red blood cells.
Platelets
- Platelet Count: Blood cell particles that play a role in forming blood clots.
- MPV (Mean Platelet Volume): The average size of platelets in the blood, providing information about platelet production and activity.
White Blood Cell Differential
- Neutrophils: The most common white blood cell type, created by your bone marrow to combat inflammatory and infectious conditions.
- Lymphocytes: B cells and T cells that fight bacteria and other pathogens, found mainly in your lymph system.
- Monocytes: Work alongside neutrophils to fight infections and clear away dead or damaged cells.
- Eos (Eosinophils): White blood cells that become active in response to allergies and certain infections.
- Basophils: Help detect infections early, support wound healing, and respond to allergic reactions.
- Immature Granulocytes: A component of your white blood cell differential included in this panel. (Labcorp only)

FAQ
1. Do I need to fast or prepare for this panel?
Fasting for at least 12 hours is required before your blood draw. No other preparation instructions, such as medication or activity restrictions, are specified for this panel.
2. How quickly will I get results?
Results are typically available in 1-2 business days. Turnaround may take longer depending on weather, holidays, or other lab delays.
3. What can this panel tell me?
Because this panel pairs a metabolic panel, a longer-term glycemic marker, and a complete blood count, it can offer a wider view than a single test alone. Glucose reflects your blood sugar at the moment of the draw, while Hemoglobin A1c reflects an average over months, so the two answer different questions. Kidney, liver, and electrolyte results add context about other organ systems, and the CBC adds information about your blood cells. Each category stands on its own and should be reviewed together rather than in isolation.
4. What factors can affect my results?
Not fasting for the required 12 hours can affect your glucose result specifically, since it is a point-in-time measurement. Hemoglobin A1c is less sensitive to same-day fasting because it reflects a longer average. Hydration, illness, and recent activity can also influence kidney, liver, and blood count values in general ways, though the source does not specify particular restrictions beyond fasting.
5. How do I interpret results across the panel?
Interpreting this panel means looking at patterns rather than any single number. Glucose and Hemoglobin A1c measure related but different things: one reflects the moment of your draw, the other an average over months, so they should not be read as interchangeable. Kidney, liver, electrolyte, and blood count results each speak to a different body system, and a normal result in one area does not offset an abnormal result elsewhere.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
6. What should I do if one or more results are abnormal?
Bring any abnormal result to a qualified healthcare provider for review alongside the rest of your panel and your overall health picture. A single value outside the expected range does not on its own confirm a diagnosis or indicate what, if anything, needs to change. Your provider can help determine whether additional evaluation or testing is appropriate based on your full results and history.
