A Complete Blood Count with an Automated Differential WBC Count is a blood test that measures the number of different types of white blood cells (WBCs) in your blood. It helps diagnose a variety of conditions, including infections, immune system disorders, and blood cancers.
Purpose
This test helps to identify and monitor various medical conditions such as infections, anemia, immune system disorders, and blood cancers. The goal is to provide detailed information on the types and numbers of WBCs, helping doctors diagnose or monitor these conditions.
Indications
- Unexplained fever
- Signs of infection
- Chronic fatigue
- Swelling or inflammation
- Suspected immune system disorders
- Monitoring known conditions like leukemia or anemia
Preparation
- Generally, no fasting is required.

- Follow any specific instructions provided by your healthcare team.
Procedure Description
- Blood Sample Collection: A healthcare professional will draw a small sample of blood from a vein in your arm using a needle.
- Automated Analysis: The blood sample is then analyzed using an automated hematology analyzer, which counts and classifies the different types of white blood cells.
- Evaluation: The results are evaluated to determine if there are any abnormal levels or types of WBCs.
Tools/Equipment: Needle, syringe, automated hematology analyzer
Anesthesia or Sedation: Not required for this procedure
Duration
Typically, the blood draw takes about 5-10 minutes. The analysis is done within a few hours to a day.
Setting
The procedure is commonly performed in a hospital, outpatient clinic, or diagnostic laboratory.
