CBD blood, in the context of the provided reference, likely refers to blood analyzed as part of a Complete Blood Count with Differential (CBD), a comprehensive blood test. The reference indicates that this test includes a review of a peripheral blood smear by a technologist, if necessary. However, it's important to note that "CBD" also commonly refers to cannabidiol, but that is unrelated to the reference material. This response will focus on "CBD" meaning Complete Blood Count with Differential.
Complete Blood Count with Differential Explained
A Complete Blood Count (CBC) is a common blood test that evaluates the overall health and composition of your blood. The "with Differential" portion (CBD) provides more detailed information about the different types of white blood cells present in your blood.
What the CBD Test Measures:
The CBD test typically measures the following:
- Red Blood Cells (RBCs): These cells carry oxygen throughout the body. The test assesses the number, size, and shape of RBCs.
- White Blood Cells (WBCs): These cells are part of the immune system and help fight infections. The differential portion of the test identifies the different types of WBCs:
- Neutrophils
- Lymphocytes
- Monocytes
- Eosinophils
- Basophils
- Platelets: These cells help the blood clot.
- Hemoglobin: The protein in RBCs that carries oxygen.
- Hematocrit: The percentage of blood volume occupied by RBCs.
- Red Blood Cell Indices: MCV (Mean Corpuscular Volume), MCH (Mean Corpuscular Hemoglobin), and MCHC (Mean Corpuscular Hemoglobin Concentration) provide information about the size and hemoglobin content of RBCs.
Why is a CBD Test Performed?
A CBD test is often performed as part of a routine checkup or to help diagnose a variety of conditions, including:
- Infections
- Anemia
- Inflammatory conditions
- Bleeding disorders
- Leukemia
Peripheral Blood Smear Review
The reference also mentions a review of a peripheral blood smear. This involves examining a sample of blood under a microscope. A technologist will visually inspect the blood cells for any abnormalities in size, shape, or number. This review is usually triggered by abnormal results from the automated CBC and provides more detailed insights.
Therefore, "CBD blood," interpreted in the context of the reference, refers to blood that is being analyzed through a Complete Blood Count with Differential, sometimes accompanied by a microscopic review of a peripheral blood smear to assess various components of the blood and identify any abnormalities.
