What's Included
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)
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.
Ferritin
Total Iron Binding Capacity (TIBC)
- Iron Binding Capacity (TIBC): The total amount of iron that transferrin can bind, calculated by adding serum iron and unsaturated iron binding capacity (UIBC).
- UIBC (Unsaturated Iron Binding Capacity): The remaining capacity of transferrin to bind additional iron that is not already bound.
- Iron, Total: The amount of iron circulating in the blood, primarily bound to transferrin.
- Iron Saturation: The percentage of transferrin's iron-binding capacity currently occupied by iron, calculated by dividing serum iron by TIBC and multiplying by 100.
Benefits
- Reviews blood cells, metabolism, cholesterol, and iron markers in one panel.
- Includes kidney and liver-related markers alongside electrolytes.
- Provides a lipid profile with cholesterol, triglycerides, and a cholesterol ratio.
- Pairs ferritin with iron and TIBC for a closer look at iron status.
- Includes a CBC with differential to check red cells, white cells, and platelets.

FAQ
1. Do I need to fast or prepare for this test?
Yes. Maintain a stable diet for 2–3 weeks before blood collection and fast for 12–14 hours prior. Stop biotin 72 hours before collection.
2. How quickly will I get results?
Expect results in 1-2 business days. May take longer based on weather, holiday, or lab delays.
3. What can my results tell me?
Together, the CBC, chemistry markers, lipid profile, and iron tests give you several views of your health in a single blood draw. Blood cell counts, organ and electrolyte markers, cholesterol measurements, and iron indicators each add a different layer. Results may be useful for screening, evaluation, or follow-up conversations with your healthcare provider.
4. How do I interpret the results?
Meaning often comes from patterns across several markers, not from a single number. Each biomarker offers a different type of information, and values do not all rise or fall together. Your symptoms, medical history, medications, preparation, and other lab findings all add context. A single high or low value does not confirm a condition, and a single normal value does not rule one out. Review your full results with a qualified healthcare provider.
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?
Start by sharing your complete results with a qualified healthcare provider. An out-of-range value does not mean treatment is needed, and several results may need to be read together to make sense. Your provider can decide whether any further evaluation is appropriate for you.
Pre-test preparation
- Maintain a stable diet for 2–3 weeks before blood collection.
