Study Notes
Complete Blood Count (CBC)
- A set of medical laboratory tests that provide information about the cells in blood.
- Evaluates the counts of white blood cells (WBCs), red blood cells (RBCs), and platelets (PLTs).
- Reports the concentration of hemoglobin (Hb) and the hematocrit (HCT).
- Includes red blood cell indices and a white blood cell differential.
Uses of CBC
- Evaluates overall health and detects diseases and conditions, such as infections, anemia, and leukemia.
- Used as a broad screening test to determine general health status.
- Helps diagnose various diseases and conditions, such as anemia, infection, inflammation, bleeding disorder, or leukemia.
- Monitors the status of a disease or condition and the effectiveness of treatment after a diagnosis is established.
- Monitors treatment that is known to adversely affect blood cells, such as chemotherapy or radiation therapy.
Principle of CBC
- Counts and measures the size of cells by detecting and measuring electrical resistance when a liquid passes through an aperture.
- Cells impede the current and cause a measurable pulse.
Components of CBC
- Red blood cell count (RBC)
- Hemoglobin (Hgb)
- Hematocrit (Hct)
- Mean corpuscular volume (MCV)
- Red blood cell distribution width (RDW)
- Neutrophils
- Lymphocytes
- Monocytes
- Platelet Count (PLT)
- White blood cell (WBC)
- Mean corpuscular hemoglobin (MCH)
- Mean corpuscular hemoglobin concentration (MCHC)
Procedure
- Sample is collected by drawing blood into a tube containing an EDTA anticoagulant to stop its natural clotting.
