Often the first CBC test shown is the white blood cell count. White blood cells, also called leukocytes, are a major component of your body’s immune system. Your body produces more WBCs when you have an infection or allergic reaction. There are five major types of WBCs (covered below), but many blood test result reports list each of these at the bo...
Red blood cells often appear next on the report. RBCs deliver oxygen to tissues throughout your body. High RBC counts can be the result of dehydration, kidney problems, or a heart condition. Low RBC counts can indicate anemia, nutritional deficiencies, bone marrow damage, or kidney problems. A high RBC could also signal fatty liver disease, a condi...
These test results often appear under the RBC section because they further examine the health and function of your red blood cells. Hemoglobin is the protein in red blood cells that carries oxygen. Its measurement can help your doctor tell if your organs and tissues are getting enough oxygen. Hematocrit results show the volume of blood taken up by ...
These two tests usually appear next. Platelets are fragments of blood cells. They help wounds heal and prevent excessive bleeding by forming clots. A low platelet count — below 150,000 platelets per microliter (mcL) — can indicate risk for excessive bleeding, while a high count (400,000 or above) may indicate a risk for blood clots. The mean platel...
Oddly, the results for the five types of white blood cells — basophils, eosinophils, neutrophils, lymphocytes, and monocytes — often appear below the list of red blood cell results. Measuring the amounts and health of these cells is helpful in identifying infections and allergies. For example, neutrophils are like the EMTs of your blood. They’re im...
