CPT4 code
Name of the Procedure:
Complete Blood Count (CBC), Automated
Summary:
A Complete Blood Count (CBC) is a common blood test that measures various components of your blood, including hemoglobin (Hgb), hematocrit (Hct), red blood cells (RBC), white blood cells (WBC), and platelets. The test is often performed using automated laboratory machines.
Purpose:
The CBC helps diagnose a variety of conditions, such as infections, anemia, and other blood disorders. It provides essential information about your overall health and the functioning of your blood cells.
Indications:
Specific symptoms or conditions that may prompt a CBC include fatigue, weakness, infection, inflammation, bruising, or bleeding. It is also commonly ordered as part of routine health exams.
Preparation:
Typically, no special preparation is needed for a CBC. However, if the CBC is part of a more extensive set of blood tests, you may be required to fast.
Procedure Description:
- A healthcare professional will clean the area on your arm where the blood will be drawn.
- A tourniquet will be placed around your upper arm to fill the veins with blood.
- A needle is inserted into a vein to collect the blood sample.
- The blood is then sent to a laboratory, where automated machines analyze its components.
Duration:
The blood draw itself takes only a few minutes. Laboratory analysis may take a few hours to a day, depending on the facility.
Setting:
The procedure is performed in various settings including hospitals, outpatient clinics, and specialized laboratory centers.
Personnel:
Typically performed by a phlebotomist, nurse, or a medical assistant. Laboratory technicians analyze the sample.
Risks and Complications:
Risks are minimal but may include minor bruising or discomfort at the needle site. Rarely, infection or excessive bleeding can occur.
Benefits:
Identifies various conditions and diseases, helping in early diagnosis and treatment. Results are generally available quickly, aiding prompt medical decisions.
Recovery:
Post-procedure care is usually unnecessary. You can resume normal activities immediately. Any minor bruising or discomfort usually resolves on its own.
Alternatives:
No direct alternatives exist for a CBC as it is a unique and comprehensive test of blood components. However, specific tests might be done to focus on particular issues, such as a reticulocyte count or a differential white blood cell count.
Patient Experience:
You might feel a slight prick when the needle is inserted. Afterward, you can expect minimal discomfort. Communication with your healthcare provider can help manage any anxiety you may have. Pain management and comfort measures are typically not necessary, but inform your provider if you have concerns.
