Complete Blood Count (CBC)

Hemoglobin (Hgb) is the oxygen-carrying protein inside red blood cells. On a lab report or blood test, Hgb helps show how much oxygen-carrying material is present in the blood and is usually reported as part of a CBC. Hemoglobin reference range values vary by age, sex, altitude, and lab method, so the Hemoglobin test result is best read with related markers such as hematocrit (Hct), red blood cell count (RBC), and mean corpuscular volume (MCV).

White Blood Cell Count (WBC) is a lab value that measures how many white blood cells are present in a blood sample. On a lab report, WBC helps describe immune-cell concentration in the blood and is commonly included in a complete blood count (CBC).

Red Blood Cell Count (RBC) is a measure of how many red blood cells are present in a given volume of blood. RBC on a blood test helps describe blood composition and is commonly reported on a CBC, where it is read alongside related markers such as hematocrit (Hct) and mean corpuscular volume (MCV).

Hematocrit (Hct) is the percentage of blood volume made up of red blood cells. On a Hematocrit on a blood test, Hct helps describe how concentrated the red cell portion is compared with plasma. It is commonly included in a CBC and is read with RBC and MCV for a fuller picture of blood composition.

Platelet Count (PLT) is a lab value that measures the number of platelets in blood. PLT appears on a blood test, especially a complete blood count (CBC), and helps describe the cell makeup of the sample. A Platelet Count lab report result is often reviewed with other CBC markers to understand overall blood composition.

Mean Corpuscular Volume (MCV) is the average size of red blood cells measured in a blood sample. On a lab report or blood test, MCV helps describe red cell size as part of a CBC and is often read with other red blood cell markers. It is a numerical summary, not a stand-alone conclusion, and is used to compare a person’s result with the Mean Corpuscular Volume normal range.

Mean Corpuscular Hemoglobin (MCH) is the average amount of hemoglobin in each red blood cell, reported as part of the CBC and often abbreviated as MCH. On a blood test or lab report, it helps describe red blood cell composition alongside markers such as MCV, RBC, and hematocrit (Hct).

Mean Corpuscular Hemoglobin Concentration (MCHC) is a CBC measurement that shows how concentrated hemoglobin is inside red blood cells. MCHC on a blood test helps describe red cell composition alongside markers like MCV, MCH, hematocrit (Hct), and red blood cell count (RBC).

Red Cell Distribution Width (RDW) is a CBC value that shows how much red blood cell size varies from cell to cell. On a Red Cell Distribution Width blood test, the result helps describe whether the red cell population is fairly uniform or more mixed in size. RDW is often read together with MCV, RBC, Hct, and hemoglobin for a fuller view of red cell measurements.

Mean Platelet Volume (MPV) is a CBC lab value that shows the average size of platelets in the blood. On a lab report, MPV helps describe platelet production and turnover, and it is often read alongside the platelet count and other CBC markers. A high MPV or low MPV can shift the overall pattern of the blood test without pointing to one single explanation.

Neutrophils are a type of white blood cell measured on a CBC. A Neutrophils test result usually appears as a percentage or absolute count and helps describe the balance of white blood cells on a blood test. The Neutrophils normal range can vary by lab method and reporting format.

Lymphocytes is a white blood cell measure that shows how much of the total white blood cell count is made up of Lymphocytes. On a blood test, it is usually reported as a percentage in the CBC and helps describe the balance of white blood cell types in the blood.

Monocytes is a white blood cell measurement reported on a complete blood count (CBC). It shows the share or number of Monocytes, a type of white blood cell, in a blood sample. On a lab report, Monocytes helps describe the overall white blood cell pattern and is often read with other CBC values.

Eosinophils is a white blood cell type measured on a blood test, usually as part of a CBC. Eosinophils on a lab report helps describe the makeup of the white blood cell portion of blood and how that mix compares with other CBC markers.

Basophils is a white blood cell subtype that appears on a CBC and is reported as part of the blood’s cell differential. On a Basophils on a blood test, it shows how much of the white cell mix is made up of basophils, which helps describe the overall makeup of the blood report.

Reticulocytes are immature red blood cells released from the bone marrow into the bloodstream. On a lab report or blood test, Reticulocytes help show how actively the body is making new red blood cells and are often reviewed with CBC results.
