The complete blood count (CBC) is a test that evaluates the cells that circulate in blood. Blood consists of three types of cells suspended in fluid called plasma: white blood cells (WBCs), red blood cells (RBCs), and platelets (PLTs). They are produced and mature primarily in the bone marrow and, under normal circumstances, are released into the bloodstream as needed. A CBC is typically performed using an automated instrument that measures various parameters, including counts of the cells that are present in a person's sample of blood. The results of a CBC can provide information about not only the number of cell types but also can give an indication of the physical characteristics of some of the cells. A standard CBC includes the following: Evaluation of white blood cells: WBC count; may or may not include a WBC differential Evaluation of red blood cells: RBC count, hemoglobin (Hb), hematocrit (Hct) and RBC indices, which includes mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW). The RBC evaluation may or may not include reticulocyte count. Evaluation of platelets: platelet count; may or may not include mean platelet volume (MPV) and/or platelet distribution width (PDW) Significant abnormalities in one or more of the blood cell populations can indicate the presence of one or more conditions. Typically other tests are performed to help determine the cause of abnormal results. Often, this requires visual confirmation by examining a blood smear under a microscope. A trained laboratorian can evaluate the appearance and physical characteristics of the blood cells, such as size, shape and color, noting any abnormalities that may be present. Any additional information is noted and reported to the healthcare provider. This information gives the health practitioner additional clues as to the cause of abnormal CBC results. The three types of cells evaluat - How Is It Used?
The complete blood count (CBC) is often used as a broad screening test to determine an individual's general health status. It can be used to: Screen for a wide range of conditions and diseases Help diagnose various conditions, such as anemia, infection, inflammation, bleeding disorder or leukemia, to name just a few Monitor the condition and/or effectiveness of treatment after a diagnosis is established Monitor treatment that is known to affect blood cells, such as chemotherapy or radiation therapy A CBC is a panel of tests that evaluates the three types of cells that circulate in the blood. A CBC includes the following: Evaluation of white blood cells, the cells that are part of the body's defense system against infections and cancer and also play a role in allergies and inflammation: White blood cell (WBC) count is a count of the total number of white blood cells in a person's sample of blood. White blood cell differential may or may not be included as part of the panel of tests. It identifies and counts the number of the various types of white blood cells present. The five types include neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Evaluation of red blood cells, the cells that transport oxygen throughout the body: Red blood cell (RBC) count is a count of the actual number of red blood cells in a person's sample of blood. Hemoglobin measures the total amount of the oxygen-carrying protein in the blood, which generally reflects the number of red blood cells in the blood. Hematocrit measures the percentage of a person's total blood volume that consists of red blood cells. Red blood cell indices are calculations that provide information on the physical characteristics of the RBCs: Mean corpuscular volume (MCV) is a measurement of the average size of a single red blood cell. Mean corpuscular hemoglobin (MCH) is a calculation of the average amount of he - When Is It Ordered
The CBC is a very common test. Many people have a CBC performed when they have a routine health examination. If a person is healthy and has results that are within normal limits, then that person may not require another CBC until their health status changes or until their healthcare provider feels that it is necessary. A CBC may be ordered when a person has any number of signs and symptoms that may be related to disorders that affect blood cells. When an individual has fatigue or weakness or has an infection, inflammation, bruising, or bleeding, a health practitioner may order a CBC to help diagnose the cause and/or determine its severity. When a person has been diagnosed with a disease known to affect blood cells, a CBC will often be ordered on a regular basis to monitor their condition. Likewise, if someone is receiving treatment for a blood-related disorder, then a CBC may be performed frequently to determine if the treatment is effective. Some therapies, such as chemotherapy, can affect bone marrow production of cells. Some medications can decrease WBC counts overall. A CBC may be ordered on a regular basis to monitor these drug treatments. - What Does The Test Result Mean?
A health practitioner typically evaluates and interprets results from the components of the CBC together. Depending on the purpose of the test, a number of additional or follow-up tests may be ordered for further investigation. The following tables briefly and generally explain what the result for each component of the CBC may mean. For detailed information on each test component, click on the name of the component to go to the specific article. To see an example of a CBC lab report, see this sample report. Note: The reference ranges provided here represent a theoretical guideline that should not be used to interpret your test results. Some variation is likely between these numbers and the reference range reported by the lab that ran your test. Please consult your doctor. For more information on reference ranges, please read Reference Ranges and What They Mean. Reference ranges listed here are for adults older than 18 years old. They are not available for youths 0-18 years old due to wide variability. See the child's lab report for reference ranges. Conventional Units are typically used for reporting results in U.S. labs. SI Units are used to report lab results outside of the U.S. Components of the CBC WBC Evaluation Test Reference Range2 Examples of causes of a low count Examples of causes of a high count White Blood Cell Count (WBC) Conventional Units1 4,500-11,000 white blood cells per microliter (mcL) SI Units1 4.5-11.0 x 109 per liter (L) Known as leukopenia Bone marrow disorders or damage Autoimmune conditions Severe infections (sepsis) Lymphoma or other cancer that spread to the bone marrow Dietary deficiencies Diseases of immune system (e.g., HIV/AIDS) Known as leukocytosis Infection, most commonly bacterial or viral Inflammation Leukemia, myeloproliferative neoplasms Allergies, asthma Tissue death (trauma, burns, heart attack) Intense exercise or severe stress White Blood Cell Differ - Is There Anything Else I Should Known?
Many different conditions can result in increases or decreases in blood cell populations. Some of these conditions may require treatment, while others may resolve on their own. Recent blood transfusions affect the results of the CBC. Normal CBC values for babies and children are different from adults. The laboratory will supply the reference ranges for various age groups, and a health practitioner will take these into consideration when interpreting data. My CBC report includes a result for immature platelet fraction (IPF). What is it? IPF is the relative number of immature platelets (also called reticulated platelets) in the blood. Platelets are produced in the bone marrow and are normally not released into the bloodstream until they have matured. When platelet numbers in the blood are low (thrombocytopenia), it stimulates the bone marrow to produce platelets faster. When the need is great and when production cannot keep up with "demand," then an increased number of immature platelets will be released into the bloodstream. This IPF test result would be one of the values reported when blood is evaluated using an automated hematology analyzer. The IPF may be used to help a healthcare provider determine the likely cause of a person's thrombocytopenia, that is, decrease in production by the bone marrow (IPF is low) versus increased loss of platelets in the blood (IPF is higher). Lab test results including platelet count and IPF can also help determine if a person needs a platelet transfusion and help monitor bone marrow recovery, such as after a bone marrow transplant. Other uses are being studied and the test's ultimate clinical utility has not yet been well determined. My CBC report includes a result for reticulocyte hemoglobin. What is it? The hemoglobin inside of reticulocytes can be measured and reported as either a mean reticulocyte hemoglobin content (CHr) or a reticulocyte hemoglobin equivalent (Ret-He), depending upon the test method used.
