What this test is

This test measures the numbers and types of cells in your blood, including red blood cells, white blood cells, and platelets. The differential part provides a breakdown of the different white blood cell types. It is often used as a general health check or to help evaluate symptoms like fatigue, weakness, or infection.

What it measures

  • Red blood cell count — reflects the number of oxygen-carrying cells
  • Hemoglobin — indicates the oxygen-carrying protein in red blood cells
  • Hematocrit — shows the proportion of blood made up of red blood cells
  • White blood cell count — reflects the number of infection-fighting cells
  • Platelet count — indicates cells that help with blood clotting
  • Differential — breaks down white blood cells into types like neutrophils, lymphocytes, and monocytes

What the test involves

A blood sample is collected, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test as part of a routine checkup or to help investigate symptoms such as tiredness, fever, or unusual bruising. It can also be used to monitor a known condition or the effects of certain treatments.

Preparation

In most cases, no special preparation is needed, but you should follow any instructions provided by the collection lab. This may include fasting or avoiding certain medications, so check with the lab beforehand.

How results are reported

Results are typically reported as numbers for each cell type, along with a reference range. Reference ranges can vary between laboratories, so your results should be interpreted in the context of the lab that performed the test.
