Name of the Procedure:

Blood Count; Automated Differential WBC Count
Common Name(s): Complete Blood Count with Differential (CBC with Diff), Automated Differential

Summary

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.
• Inform your healthcare provider about any medications or supplements you are taking.
• Follow any specific instructions provided by your healthcare team.

Procedure Description

1. Blood Sample Collection: A healthcare professional will draw a small sample of blood from a vein in your arm using a needle.
2. Automated Analysis: The blood sample is then analyzed using an automated hematology analyzer, which counts and classifies the different types of white blood cells.
3. 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.

Personnel

• Phlebotomist or nurse (for blood sample collection)
• Laboratory technician (for sample analysis)
• Physician (to interpret the results)

Risks and Complications

• Common Risks: Mild discomfort or bruising at the puncture site.
• Rare Risks: Infection or excessive bleeding.

Benefits

• Provides crucial information about your immune system and blood health.
• Helps in the early detection and management of various medical conditions.
• Results are usually available quickly, enabling prompt treatment if needed.

Recovery

• Post-Procedure Care: Keep the puncture site clean and dry. Apply a bandage if needed.
• Expected Recovery Time: Immediate; you can resume normal activities right after the procedure.
• Follow-Up: Based on results, your healthcare provider may recommend further tests or treatments.

Alternatives

• Manual Differential WBC Count: More time-consuming, involves microscopic examination.

• Other Blood Tests: Specific tests targeting certain conditions, such as C-reactive protein for inflammation.

  Pros and Cons of Alternatives:

• Manual Differential: More detailed but slower and requires a skilled technician.
• Specific Tests: Targeted information but might miss other underlying conditions.

Patient Experience

During the blood draw, you may feel a quick pinch or slight stinging. Afterward, there might be minor swelling or bruising at the puncture site. Use over-the-counter pain relief if needed, and rest assured that discomfort usually resolves quickly.
