Complete Blood Count vs. Full Blood Count
What's the Difference?
Complete Blood Count (CBC) and Full Blood Count (FBC) are two terms that are often used interchangeably to refer to the same test. Both tests measure the levels of various components in the blood, such as red blood cells, white blood cells, and platelets. However, some healthcare providers may use the term CBC to refer to a basic blood test that includes only the most essential components, while FBC may refer to a more comprehensive test that includes additional parameters such as hemoglobin, hematocrit, and mean corpuscular volume. Ultimately, both tests provide valuable information about a person's overall health and can help diagnose a wide range of medical conditions.

Further Detail
Introduction
When it comes to assessing a person's overall health, blood tests are an essential tool. Two common types of blood tests that are often ordered by healthcare providers are the Complete Blood Count (CBC) and the Full Blood Count (FBC). While these tests may sound similar, they actually provide different types of information about a person's blood composition and overall health.
Complete Blood Count (CBC)
A Complete Blood Count (CBC) is a common blood test that provides information about the different types of cells in the blood, including red blood cells, white blood cells, and platelets. This test measures the number of each type of cell present in a person's blood, as well as other important parameters such as hemoglobin levels and hematocrit. A CBC can help healthcare providers diagnose a variety of conditions, including anemia, infections, and blood disorders.
Full Blood Count (FBC)
A Full Blood Count (FBC) is a more comprehensive blood test that includes all the parameters measured in a CBC, as well as additional tests such as a differential white blood cell count and a reticulocyte count. The differential white blood cell count provides information about the different types of white blood cells present in the blood, while the reticulocyte count measures the number of young red blood cells. An FBC can provide more detailed information about a person's blood composition and can help healthcare providers diagnose a wider range of conditions.
Parameters Measured
Both the CBC and FBC measure similar parameters, such as the number of red blood cells, white blood cells, and platelets in the blood. However, the FBC includes additional parameters that are not measured in a standard CBC, such as the differential white blood cell count and the reticulocyte count. These additional parameters can provide more detailed information about a person's blood composition and can help healthcare providers make a more accurate diagnosis.
Uses
Both the CBC and FBC are commonly used to help diagnose a variety of conditions, such as anemia, infections, and blood disorders. However, the FBC is often ordered when more detailed information about a person's blood composition is needed. For example, if a healthcare provider suspects a bone marrow disorder, they may order an FBC to get a more comprehensive picture of the person's blood composition. In contrast, a CBC may be sufficient for diagnosing more common conditions such as iron deficiency anemia.
Cost
One of the main differences between a CBC and an FBC is the cost. Because the FBC includes additional tests that are not included in a standard CBC, it is typically more expensive. Healthcare providers may choose to order a CBC initially and then follow up with an FBC if more detailed information is needed. This approach can help reduce costs while still providing the necessary information for an accurate diagnosis.
Conclusion
In conclusion, both the Complete Blood Count (CBC) and the Full Blood Count (FBC) are valuable tools for assessing a person's overall health and diagnosing a variety of conditions. While the CBC provides basic information about a person's blood composition, the FBC offers more detailed information that can help healthcare providers make a more accurate diagnosis. The choice between a CBC and an FBC will depend on the specific needs of the patient and the healthcare provider's clinical judgment.
