Test Description: The CBC is a combination report of a series of tests of the peripheral blood. The quantity, percentage, variety, concentrations, and quality of blood cells are identified. The tests usually included in a CBC are hematocrit, hemoglobin, red cell count, red blood cell indices, white cell count, platelet count , and differential white blood cell count. Red blood cell indices consist of the following tests: MCV, MCHC, MCH. The differential white blood cell count consists of neutrophils, eosinophils, basophils, lymphocytes, and monocytes.

Consent Form: Not required

List of Equipment: Purple-top tube; needle and syringe or vacutainer; alcohol swab

Test Procedure:
1. Label the specimen tube
2. Obtain a 5-mL blood sample.
3. Do not agitate the tube (Agitation may cause RBC hemolysis).
4. Send the tube to the lab

Clinical Implications and Indications:
1. The CBC is a frequently ordered outpatient and inpatient basic screening and diagnostic test that provides information about the hematological system and many other systems. It is used in routine physical examination and in the diagnosis of a wide range of conditions and diseases of children and adults.

Nursing Care:
Before test: Explain the test procedure and the purpose of the test. Assess the client’s knowledge of the test.
During Test: Adhere to standard precautions.
After Test: Apply pressure to venipuncture site. Explain that some bruising, discomfort, and swelling may appear at the site and that a warm, moist compress can alleviate this. Monitor for signs of infection.

Potential Complications: Bleeding and bruising at venipuncture site.

Interfering Factors: Hypovolemia and fluid overload may alter results.

Nursing Considerations:
Pediatric: Infants and children will need assistance in remaining still during the venipuncture and age-appropriate comfort measures following the test.
