Who Performs a CBC Test?

What does a CBC test measure?

  • A complete blood count (CBC) involves multiple measurements that include the Hematocrit, hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), percentage and absolute differential counts, platelet count, red cell count (RBC) & white blood cell count (WBC).
  • A hematocrit means that measures the percentage of red blood cells in your blood. Red blood cells are important because they carry oxygen throughout your body.
  • A standard CBC includes many elements related to the red blood cells, white blood cells, and platelets that have been described in the following sections. 

 

CBC Test Results

CBC Test results are given in numbers, and often it depends on certain factors, including sex, age, and medical history. 

  • It should be compared to a normal reference range or to previous results to have meaning. Normal ranges for CBCs might vary slightly from the lab.
  • A Complete Blood Count (CBC) usually provides a piece of general information that can give doctors clues about possible health problems.

  • The information might also help the doctor to develop or revise treatment plans.
  • A doctor who is familiar with your medical history and overall health is the best person to explain your CBC results and what they mean for you.

The common terms used to describe CBC test results are:

  • Anaemia - Not enough healthy RBCs or hemoglobin.
  • Leukopenia - A low number of WBCs.
  • Neutropenia - A low number of neutrophils.
  • Leukocytosis - An increased number of WBCs.
  • Thrombocytopenia - A low number of platelets.
  • Thrombocytosis - An increased number of platelets.

Component Male Female
White Blood Cells 4,500 to 11,000 cells/mcL 4,500 to 11,000 cells/mcL
Red Blood Cells 4.5 to 5.6 million cells/mcL 3.8 to 5.2 million cells/mcL

CBC Test Interpretation

Here's an example of a CBC Test interpretation.

CBC Component High Value Interpretation Low Value Interpretation
WBC Infection, inflammation Bone marrow suppression
RBC Polycythemia Anemia
Hemoglobin Polycythemia Anemia
Hematocrit Polycythemia Anemia
Platelets Thrombocytosis Thrombocytopenia

 

CBC Test High Levels

Here are the potential causes of CBC Test High Levels.

Component High Value Cause
White Blood Cells Infection or inflammatory conditions.
Red Blood Cells Dehydration or chronic lung diseases.
Hemoglobin Polycythemia or lung diseases.
Hematocrit Dehydration or lung diseases.
Platelets Infection or bone marrow disorders.

 

CBC Test Low Levels

Here are the potential causes of CBC Test Low Levels.

Component Low Value Cause
White Blood Cells Bone marrow failure or immune disorders.
Red Blood Cells Anemia or bleeding disorders.
Hemoglobin Iron deficiency or blood loss.
Hematocrit Anemia or fluid overload.
Platelets Bone marrow disorders or medication side effects.

Summary

High levels of CBC components indicate possible infections, inflammation, or blood disorders, while low levels can suggest anemia, nutritional deficiencies, or bone marrow problems.

 

Abnormal RBC counts

A low RBC count may be due to the following:

  • Anaemia is due to prolonged bleeding or blood loss (hemorrhage), a diet lacking iron or certain vitamins, certain types of chemotherapy, blood disorders, or chronic disease.
  • Hodgkin's lymphoma and other lymphomas.
  • The cancers of the blood, such as leukemia and multiple myeloma.
  • Some myeloproliferative disorders.

 

A high RBC count may be due to the following:

  • Severe dehydration, such as from severe diarrhea.
  • Kidney tumors.
  • Lung diseases.
  • Polycythemia vera (a myeloproliferative disorder).

 

Abnormal WBC counts

A Low WBC count may be due to the following:

  • Viral infection.
  • A severe bacterial infection.
  • Suppression of bone marrow is caused by treatments like chemotherapy or radiation therapy.
  • Bone marrow diseases, such as leukemia or myelodysplastic syndrome (MDS).
  • Anaemia.

 

A High WBC count may be due to the following:

  • Infection.
  • Leukaemia.
  • Some myeloproliferative disorders.
  • Some types of cancer, such as bronchogenic carcinoma.
  • Certain drugs, such as colony-stimulating factors.
  • Stress, allergies, or tissue injury.

 

Abnormal Platelet Counts

A Low Platelet Count may be due to the following:

  • Some of the cancer types, such as leukemia or lymphoma.
  • Autoimmune diseases.
  • Bacterial infection.
  • Viral infection.
  • Chemotherapy, or radiation therapy.
  • Having many blood transfusions.

 

A High Platelet Count may be due to the following:

  • prolonged bleeding or blood loss (hemorrhage).
  • Anaemia from low iron levels.
  • Infection (inflammation).
  • Surgical removal of the spleen (splenectomy).
  • Polycythemia vera.
  • Some types of leukemia.
