The normal range is just a guide. Your doctor will also look at your results based on your age, health, and other factors. A value that isn't in the normal range may still be normal for you. Normal values for the complete blood count (CBC) tests depend on age, sex, how high above sea level you live, and the type of blood sample.

Blood can be drawn from a vein, or if you have a special IV inserted for surgery, it may be drawn from that line. Blood is typically drawn from a blood vessel directly into a special type of test tube that prevents it from clotting. It is then sent to a lab for processing.
Keep in mind that "normal" values can vary slightly based on simple changes such as the elevation at which you live. Other factors which can affect values are hydration status and use of certain medications. Different labs also have slight differences in the "normal ranges." The information and potential diagnosis listed for high and low levels in ...
Red blood cellscarry oxygen to the body. Low results can indicate blood loss, problems with the bone marrow, leukemia, and malnutrition. High results can indicate heart problems, kidney disease, over transfusion and dehydration.
These cellsare the infection-fighting portion of the blood and play a role in inflammation. A low count can indicate bone marrow problems or other issues preventing the body from making enough of these blood cells, chemical exposure, autoimmune disease, and problems with the liver or spleen. High levels can indicate the presence of tissue damage (b...
This is the percentage of the bloodthat is composed of red blood cells. Low hematocrit levelscan indicate anemia, blood loss, bone marrow problems, malnutrition and more. High levels can indicate dehydration, polycythemia vera, smoking, living at a high altitude and heart diseases that are present at birth.
Hemoglobinis a protein on red blood cells that carries oxygen. Too few red blood cells is called anemia. Low levels may indicate blood loss, caused by trauma, surgery, injury or possibly a long-term but small amount of bleeding in the body, such as an ulcer in the stomach. It can also indicate an inability to make enough blood, which is often cause...
Platelets are the part of the blood that makes the blood clot. Low levels may indicate the person is receiving chemotherapy, hemolytic anemia, the presence of a replacement heart valve, leukemia, or a recent blood transfusion. Low levels after surgery may be reflective of a "consumptive" coagulopathy, where platelets are used during the clotting an...
Mar 14, 2024 · A complete blood count (CBC) is a blood test that measures amounts and sizes of your red blood cells, hemoglobin, white blood cells and platelets. A provider can use it to monitor and diagnose medical conditions and check on the health of your immune system. Infections, medications, anemia and cancer can cause abnormal results.
- Red blood cells are the part of the blood that carry oxygen and carbon dioxide throughout the body. Red blood cells are made up of hemoglobin, whic...
- White blood cells are the part of the blood that fight infections. White blood cells are measured in thousands per cubic milliliter (K/ml3) of bloo...
- Doctors may order a CBC when the patient has signs of infection, is weak or tired, or has inflammation (swelling), bruising, or bleeding. Some of t...
- Complete blood count. A routine complete blood count (CBC) checks for levels of 10 different components of every major cell in your blood: white blood cells, red blood cells, and platelets.
- Basic metabolic panel. A basic metabolic panel (BMP) usually checks for levels of eight compounds in the blood: calcium. glucose. sodium. potassium. bicarbonate.
- Comprehensive metabolic panel. A comprehensive metabolic panel (CMP) includes all the measurements of a BMP as well as additional proteins and substances related to liver function, such as
- Lipid panel. This test checks levels of two types of cholesterol: high-density lipoprotein (HDL), or “good” cholesterol. low-density lipoprotein (LDL), or “bad” cholesterol.
Aug 3, 2024 · By measuring the levels of different components within the blood—such as red blood cells, white blood cells, and platelets—a CBC provides critical insights into the body's physiological status. A CBC with differential goes a step further by breaking down the white blood cell count into its various types, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
Jan 16, 2024 · The CBC encompasses various components like red and white blood cell counts, haemoglobin, haematocrit, and platelets. CBC test normal ranges vary by age, gender, and individual health factors. For red blood cells, a typical count falls within 4.5 to 5.5 million cells per microliter. White blood cell counts range from 4,000 to 11,000 cells per ...

May 15, 2024 · The CBC, a common screening blood test, gives important information about whether a person has anemia and what might be causing it, whether the bone marrow (where blood cells are produced) is functioning normally, and whether a person may be dealing with a bleeding disorder, infection, inflammation, or certain kinds of cancer.
