Complete Blood Count (CBC) Test

This CBC blood test is the first step to detecting illnesses that can affect your overall health.

Your blood is perhaps the most essential substance in your body—transporting life-sustaining nutrients, hormones and oxygen all while carrying waste products for removal through the lungs, liver and kidneys. Blood is also your body's most crucial defense against fighting infections.

 

This complete blood count (CBC) test counts the cells that circulate in your blood, which can provide valuable information to you and your healthcare provider about your overall health. This full blood panel may also be a first step to detecting health conditions such as anemia, inflammation, blood disorders and infection. This panel measures your red blood cells (RBCs), white blood cells (WBCs), and platelets. This is a CBC with differential blood test, which also measures the amount of each type of WBCs that you have in your body (neutrophils, lymphocytes, monocytes, basophils, and eosinophils).

 

Note: A CBC test is not a diagnostic test and cannot confirm any specific illness or disease. Further testing and medical consultation may be required to determine the cause of abnormal results.

What's Tested
  • Red Blood Count

    Measures the number of red blood cells (erythrocytes). Red blood cells contain hemoglobin, a protein that carries oxygen throughout the body.

  • White Blood Count

    Detects the number of white blood cells (leukocytes) in the body, cells that fight off infections and foreign agents that may infect the body.

  • Hemoglobin

    Measures the amount of hemoglobin in the blood, the oxygen-carrying protein in red blood cells.

  • Hematocrit

    Measures the proportion of red blood cells to the fluid component (or plasma) in your blood.

  • Platelet Count

    Measures the number of platelets in the blood, the cell components essential for blood clotting.

  • Immature Granulocytes

    Measures the percent of white blood cells in an early stage of development which are not usually present in significant amounts in the blood.  

  • Monocytes

    Measures the level of monocytes, the type of white blood cells responsible for breaking down germs or bacteria that enter the body.  

  • Lymphs

    Measures the level of lymphocytes, the white blood cells that are vital to producing antibodies and helping the body fight against bacteria, viruses, and other threats.

  • Neutrophils

    Measures the level of neutrophils, the type of white blood cells that destroy bacteria and fungi and protect the body from infections.  

  • Immature Cells

    White blood cells in an early stage of development which are not usually present in significant amounts in the blood.  

  • Eosinophils

    Measures the quantity of eosinophils in the body, a type of disease-fighting white blood cell. 

  • Basophils

    Measures the quantity of basophils in your body, a type of white blood cell produced by bone marrow that helps the body fight parasitic infections, prevents blood clotting, and mediates allergic reactions. 

  • Mean Corpuscular Volume

    Measures the average size of the red blood cells themselves. 

  • Mean Corpuscular Hemoglobin

    Measures MCH levels, the average amount of hemoglobin found in the red blood cells in the body. 

  • Mean Corpuscular Hemoglobin Concentration

    Measures MCHC levels, the average weight of hemoglobin based on the volume of red blood cells.

  • Red Cell Distribution Width

    Measures the variation of size and volume of the body’s red blood cells.  

  • Immature Granulocytes (Absolute)

    White blood cells in an early stage of development which are not usually present in significant amounts in the blood.

FAQ

  • A complete blood count (CBC) test is a blood test that measures the number of red blood cells, white blood cells and platelets in your body. A CBC test with differential includes the CBC test and a measurement of the various white blood cell types in your body, such as neutrophils, lymphocytes, monocytes, basophils and eosinophils. If you are experiencing general fatigue, unexplained bruising or bleeding, joint pain or abnormal heart rate, this test may provide insight into the cause of these symptoms and can help guide conversations with your healthcare provider.

  • The CBC test with differential may offer insights into your overall health and help screen for a variety of health conditions, such as anemia and infection.¹ However, to check your liver and kidney function, we recommend the comprehensive metabolic panel (CMP) test.

  • Healthcare providers typically recommend routine blood tests, such as a CBC test, be performed once a year.2

  • No. These two measurements tell you different things about your red blood cells.
     

    MCV and MCHC are different measurements on a Complete Blood Count (CBC).
     

    • MCV (Mean Corpuscular Volume) shows the average size of your red blood cells.
    • MCHC (Mean Corpuscular Hemoglobin Concentration) shows the average concentration of hemoglobin (the protein that carries oxygen) inside those cells.
       

    Both help your healthcare provider understand your red blood cell health, but they measure different aspects and should always be reviewed along with the rest of your complete blood count (CBC)

  • Your mean corpuscular volume (MCV) measures the average size of your red blood cells. A normal MCV means your red blood cells are within the expected size range.
     

    A low MCV means your red blood cells are smaller than average. This may be seen with:
     

    • Iron‑deficiency anemia
    • Thalassemia
    • Chronic inflammatory conditions


    A high MCV means your red blood cells are larger than average. This may occur with:
     

    • Vitamin B12 deficiency
    • Folate deficiency
    • Alcohol use
    • Certain thyroid or liver conditions


    MCV is only one part of your complete blood count (CBC). It cannot diagnose a condition by itself but reviewing it together with other CBC results may provide helpful clues.

  • Your mean corpuscular hemoglobin concentration (MCHC) measures the average concentration of hemoglobin inside your red blood cells. A normal MCHC means your red blood cells contain an expected amount of hemoglobin for their size.
     

    A low MCHC means your red blood cells have less hemoglobin than usual. This may be seen with:
     

    • Iron‑deficiency anemia
    • Thalassemia
    • Chronic inflammatory conditions
    • Certain long‑term illnesses that affect red blood cell production


    A high MCHC is less common and means the hemoglobin concentration is higher than expected. This may occur with:
     

    • Autoimmune hemolytic anemia
    • Hereditary spherocytosis
    • Severe burns
    • Certain medications or medical conditions that affect red blood cell structure


    As with MCV, MCHC is best understood by looking at your entire CBC, not on its own.

  • Your testing will be performed in a CLIA-certified clinical laboratory. Labcorp provides leading-edge medical laboratory tests and services through a national network of primary clinical laboratories and specialty testing laboratories. Our labs perform regular quality assurance testing to ensure our results are accurate.

  • Your results will be provided to you through our secure online portal to view or print. Results are also made available through a secure portal to the independent healthcare provider who placed your test order.  If you are accessing your results through your Labcorp Patient™ account, all users linked to the account will have access to all OnDemand test results. Results may also be provided to a local, state, and/or federal health authority; for example, many states require the testing laboratory and physician to report test results for certain communicable diseases, such as COVID-19, to local or state health departments.
