With a complete blood count or CBC test, you can assess your health conditions and detect infections. This test measures various components present in your blood such as red blood cells (RBC), platelets, white blood cells (WBC), hemoglobin and hematocrit [1].

Red blood cells help by transporting oxygen and white blood cells are essential for your body as they fight pathogens. While platelets aid in the blood clotting mechanism, the hemoglobin in red blood cells is the protein that carries oxygen. The hematocrit evaluation determines the quantity of red blood cells in proportion to the plasma in your blood.

If there is an abnormal result in your test when compared against the normal CBC values, it may indicate an ailment that requires further evaluation.

Getting a CBC test done is essential for the following reasons:

  • To check if you are suffering from any infection
  • To monitor a disease
  • To assess your overall health parameters
  • To track the treatment procedure you are undergoing

Doctors also prescribe this test if you have the following symptoms.

  • Pain in joints
  • Fever
  • Nausea
  • Bleeding or bruises
  • Weakness
  • Dizziness
  • Body inflammation
  • Increase in blood pressure or heartbeat

Read on to understand more about this test and normal CBC values present in a healthy individual.

How is the CBC test done?

For a complete blood count test, there is no need to fast. You can drink and eat as usual before going for the test. Your blood sample is taken after inserting the needle in your vein and then is sent for analysis to the laboratory. It is normal to feel soreness in your arm from where the blood has been extracted. In some cases, you may feel slightly dizzy after a CBC test. With the help of this blood sample, a wide range of health ailments can be detected. This helps in early diagnosis and ensures that proper medical treatment is provided on time.

Remember, to compute different kinds of WBCs, doctors recommend CBC test with differential. A CBC test without differential includes only the total count of WBCs.

What are the different conditions detected by a CBC?

Here are the different types of health conditions that can be determined by a CBC [2].

  • Deficiency of minerals and vitamins
  • Disorders affecting bone marrow
  • Anemia
  • Infections causing a decrease or increase in WBCs
  • Cancers like lymphoma or leukemia
  • Allergies due to medicines

How to interpret CBC values?

You can get the test results within 24 hours of sample collection. However, if the value exceeds the CBC test normal range, your doctor may order additional tests. The CBC normal range is actually a reference range mentioned in your report. Any value that exceeds this reference range is considered abnormal and requires medical intervention.

CBC values differ for men and women. When it comes to WBC normal range, females and males should have a count within 3500-10500 cells/mL. The complete blood count normal range of hemoglobin is between 11.5 and 15.5g/dL in women, while the total count normal value in men is between 13-17 g/dL. Refer to a complete blood count normal ranges chart to monitor the result yourself.

What do the test results indicate?

Your test report will contain two columns that include reference range and your value. If your CBC values fall within reference range, it is considered normal. However, if your results are lower or higher than reference values, it points to something abnormal. If your RBCs, hematocrit and hemoglobin values are low, it may be a hint that you are suffering from anemia. A low WBC count may indicate leukopenia, while a low platelet count means you have thrombocytopenia. If your platelet count is high, it indicates thrombocytosis [3].
