Gillis Blood Test Panel

Quick Facts

• Fasting: Fasting at least 12 hours; stop biotin 72 hours prior; no smoking before collection
• Turnaround: 2-4 business days

What's Included

Complete Blood Count (CBC) with Differential and Platelets Blood Test

White Blood Cells

• White Blood Cells (WBC): Your body's primary defense against disease, these cells help you fight infection.

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

• Glucose: The amount of sugar in your blood, used to screen for and monitor diabetes.

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.

Thyroid-Stimulating Hormone (TSH)

• TSH: A hormone produced by the pituitary gland that regulates thyroid hormone production. Helps evaluate thyroid function and identify potential thyroid disorder

Lipase

• Lipase: Measures the level of lipase, an enzyme that helps the body digest fats. This test helps evaluate pancreatic function and may help detect inflammation or other problems affecting the pancreas.

Lactic Acid Dehydrogenase

• Lactic Acid Dehydrogenase (LD): An enzyme found in many tissues, including the liver, heart, muscles, and red blood cells, that is released into the blood when cells are damaged. 

Ammonia Plasma Test

• Ammonia: Measures the amount of ammonia in the blood, a waste product normally removed by the liver. This test helps assess liver function and detect problems with how the body removes ammonia. 

Benefits

• Evaluates your red cells, white cells, and platelets in one draw.
• Includes kidney and liver-related measurements alongside blood sugar and electrolytes.
• Checks TSH to assess thyroid function.
• Includes lipase, a marker related to the pancreas.
• Adds LD and ammonia for a broader look at tissue and liver health.

Who Is This Test For?

• Adults who want a broad overview of their general health.
• Anyone who wants blood cell counts checked alongside organ function markers.
• People who want thyroid, pancreas, and liver-related markers reviewed together.
• Individuals who want lab data to discuss with their healthcare provider.

FAQ

1. Do I need to fast or prepare for this test?

Yes. Fasting for at least 12 hours is required. Stop biotin consumption at least 72 hours prior to the collection. You should not smoke prior to collection.

2. How quickly will I get results?

Plan on 2-4 business days. Results may take longer based on weather, holiday, or lab delays.

3. What can my results tell me?

Think of this panel as several views of your health in one blood draw. Blood cell counts, organ function markers, thyroid hormone, and individual enzymes each contribute a different piece. Together they give you and your healthcare provider a wider picture to review than any single test could offer.

4. How do I interpret the results?

Meaning comes from patterns, not isolated numbers. A single value rarely tells the whole story, and different markers answer different questions. Your symptoms, medical history, medications, how you prepared, and other lab findings all shape what a result means. A qualified healthcare provider can put your values in context.

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 report with a qualified healthcare provider. One out-of-range value does not diagnose a condition or automatically call for treatment. Your provider can look at how several results fit together and decide whether any further evaluation makes sense for you.

Pre-test preparation

• Fasting for at least 12 hours is required.
• Stop biotin consumption at least 72 hours prior to the collection.
• You should not smoke prior to collection.
