Quick Facts
- Sample: Blood
- Fasting: Fasting for at least 12 hours is required (see Pre-test preparation)
- Turnaround: 2-3 business days. May take longer based on weather, holiday, or lab delays.
What's Included
Vitamin B12
Vitamin B12: An essential vitamin that supports healthy nerve function, red blood cell production, and DNA formation. Measuring vitamin B12 levels helps identify deficiencies that may contribute to anemia, fatigue, or nerve problems.
Folic Acid (Folate)
Folate (Folic Acid): A B vitamin that helps the body make new cells, produce healthy red blood cells, and form DNA. Measuring folate levels helps identify deficiencies that may contribute to anemia and is especially important during pregnancy for healthy fetal development.
Comprehensive Metabolic Panel (CMP-14) with eGFR Blood Test
Blood Sugar
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.
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)
Benefits

FAQ
1. Do I need to fast or prepare for this test?
Yes, fasting for at least 12 hours is required. You should stop biotin consumption at least 72 hours prior to the collection. Your sample must be drawn before a Schilling test, transfusions, or B12 therapy is started.
2. How quickly will I get results?
Expect your results in 2-3 business days. Timing may run longer based on weather, holiday, or lab delays.
3. What can my results tell me?
Think of this panel as three complementary views of your blood. Vitamin B12 and folate levels show your status for those two nutrients. The CMP-14 adds a look at glucose, kidney, liver, and electrolyte markers, along with protein markers tied to nutrition. The CBC reports the numbers and kinds of cells in your blood.
4. How do I interpret the results?
No single number tells the whole story. Patterns across your vitamin levels, chemistry markers, and cell counts matter more than any one value, and each marker answers a different question. Your symptoms, medical history, medications, and how you prepared can all shape what your numbers mean. Your provider can review everything together with you.
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.
5. What should I do if my results are abnormal?
An out-of-range value is a prompt for a conversation, not a conclusion. Share your full report with a qualified healthcare provider, who can look at how your results fit together. One result rarely provides a complete picture, and your provider will decide whether any further evaluation is appropriate for you.
Pre-test preparation
- Fasting for at least 12 hours is required.
