Follow-up tests, such as bone marrow biopsy or genetic testing, may be necessary to determine the underlying cause. Treatment options for abnormal CBC results will depend on the specific condition diagnosed.

Getting a CBC test

When getting a CBC test, it is important to understand how it is performed, what to expect during the procedure, and how to prepare for it.

The CBC test is a simple procedure involving a blood sample drawn from a vein in your arm.

You can eat and drink normally before the test, which usually takes only a few minutes.

How is a CBC test performed?

The procedure for obtaining a CBC test involves the collection of a blood sample to assess the composition and characteristics of the blood. The CBC test process is simple and quick, typically taking only a few minutes.

Before the test, no specific preparation is required, and you can eat and drink normally. A nurse or lab technician will draw a blood sample from a vein in your arm using a needle. After the blood is collected, you can resume your routine.

The blood sample is then sent to a lab for analysis. The CBC test is highly accurate in providing valuable information about your overall health.

What to expect during the test

During the CBC test, you can expect a nurse or lab technician to draw a blood sample from a vein in your arm using a needle.

It is important to wear loose-fitting clothing that allows easy access to your arm.

The procedure takes only a few minutes, but there may be potential side effects, such as slight bruising or discomfort at the needle insertion site.

A CBC test's cost and insurance coverage may vary depending on your healthcare provider.

Fasting is not typically required for a CBC test.

How to prepare for a CBC test

To ensure an accurate CBC test, following a few preparation steps and discussing any necessary precautions with your healthcare provider is essential. Here are some preparatory instructions for getting a CBC test:

  • Fasting requirements: Sometimes, your healthcare provider may ask you to fast before the test to obtain accurate results.
  • Sample collection process: A nurse or lab tech will draw a blood sample from a vein in your arm using a needle. The process is quick and usually takes only a few minutes.
  • Potential side effects: While the CBC test is generally safe, slight discomfort or bruising may occur at the site where the blood sample was taken.

After the test, your healthcare provider will provide post-test care instructions if necessary.

Common blood components measured in a CBC

When conducting a complete blood count (CBC), several common blood components are measured, including red blood cells (RBC), white blood cells (WBC), and platelets. These components are crucial in maintaining overall health and provide valuable insights into various medical conditions.

Red blood cells (RBC)

Measuring red blood cells (RBC) is essential to a complete blood count (CBC) test. It provides valuable information about the number of RBCs in the blood, which is important for assessing overall health. Key points about RBC measurement include:

  • Normal range: The normal RBC count varies depending on age, sex, and altitude.
  • Anemia detection: A low RBC count can indicate anemia, a condition characterized by a decrease in the number of RBCs.
  • Blood oxygenation: RBCs are crucial in delivering oxygen to tissues and removing carbon dioxide.
  • CBC significance: The RBC measurement in a CBC test helps diagnose and monitor various health conditions, including anemia and blood disorders.

White blood cells (WBC)

Abnormalities in white blood cell (WBC) counts can indicate underlying health conditions such as infection, inflammation, or immune disorders. The differential count analysis of WBCs can provide valuable information about the types and quantities of white blood cells in the blood.

WBC reference ranges vary based on age, sex, and altitude. Understanding the function of WBCs is crucial in diagnosing and managing WBC disorders, as abnormal WBC counts can indicate various health issues.


How are platelets measured in a CBC?

Platelets, also known as thrombocytes, are one of the common blood components measured in a CBC.

The platelet count, the number of platelets in a given blood volume, is determined through automated cell counting machines.

These machines use electrical impedance or optical methods to count and analyze the platelets.

Additionally, platelet function can be assessed through specialized tests that evaluate platelet aggregation and other aspects of their functionality.

Platelet disorders may require further diagnostic tests, and platelet transfusion may be necessary in severe cases.

CBC with differential

A CBC with differential is a type of blood test that provides a more detailed analysis of the different types of white blood cells in the blood sample. It is typically ordered when there is a need to identify and quantify specific types of white blood cells, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils.

Interpreting the results of a CBC with differential can help healthcare professionals diagnose and monitor conditions such as infections, autoimmune disorders, and certain types of cancer.

What is a CBC with differential?

The CBC with differential is a comprehensive blood test examining the different types of white blood cells in your bloodstream. This test, also known as a complete blood count with differential, is important in assessing your immune system and detecting abnormalities.

Interpreting CBC with differential results can provide valuable information about your overall health and help diagnose infections, inflammation, or blood disorders.

CBC with differential reference values vary depending on factors like age and sex.

When is a CBC with a differential test done?

Frequently, a CBC with a differential test is performed to evaluate and monitor various health conditions, detect infections or inflammation, and assess the immune system's overall function. This test is typically ordered when a healthcare provider suspects a blood disorder, infection, or autoimmune disease. Interpreting the results of a CBC with differential requires knowledge of the normal reference ranges for each cell type. Regular CBC with differential tests are important for diagnosing and monitoring conditions such as anemia, leukemia, infections, and immune system disorders.
