A CBC test for a baby is a complete blood count that measures different components of their blood.
Understanding a CBC Test
A Complete Blood Count (CBC) is a common blood test that provides valuable information about a baby's health. It specifically looks at:
- Red blood cells: These cells carry oxygen throughout the body.
- White blood cells: These cells fight infection and are vital for the immune system.
- Platelets: These are essential for blood clotting.
The test is performed in a lab using an automated machine. According to the reference, a CBC test "tells what and how many red blood cells, white blood cells and platelets are in the blood."
Why is a CBC Test Important for Babies?
A CBC test can help:
- Evaluate overall health: It can provide a general picture of a baby's health status.
- Diagnose medical conditions: Abnormal levels of blood cells can indicate various illnesses, like infections or anemia.
- Monitor treatment effectiveness: If a baby is undergoing treatment, a CBC can check if the treatment is working.
Key Components Measured in a CBC
The reference specifies that the test measures the what and how many of:
| Component | Function |
|---|---|
| Red Blood Cells | Carry oxygen to body tissues |
| White Blood Cells | Fight infection |
| Platelets | Help blood clot |
How is a CBC test performed?
A small blood sample is needed for a CBC test. This is usually taken by:
- A small needle prick, usually on the heel for newborns.
- From a vein in the arm if needed for older babies.
The blood sample is then processed by a special machine in a laboratory. This machine analyzes the components of the blood, providing the data needed for evaluation.
