Blood Test

Complete Blood Count (CBC)

A CBC is a group of blood tests that measure the number and size of the different cells in your blood. It measures red blood cells (carry oxygen), white blood cells (fight infections), platelets (help blood clot), hemoglobin, hematocrit, and mean corpuscular volume (MCV).

Also known as: Full blood count, Blood cell count, FBC

Normal Range

Parameter	Reference Range
Hemoglobin (Men)	13–17 g/dL
Hemoglobin (Women)	12–15 g/dL
RBC	4.5–5.5 million/µL
WBC	4–11 ×10³/µL
Platelets	150–450 ×10³/µL

Who Should Take This Test?

A complete blood count is often part of a routine checkup. It is also used to monitor a condition or treatment that may affect your blood cell counts such as infections, anemia, immune system disorders, and blood cancers.

How It Works

A health care professional takes a blood sample from a vein in your arm using a small needle. After the needle is inserted, a small amount of blood is collected into a test tube. This usually takes less than five minutes.

Preparation

Usually, no special preparation is necessary. If your provider ordered other tests on your blood sample, you may need to fast for several hours before the test.
