Blood Count; Leukocyte (WBC), Automated
Name of the Procedure
Common Name(s): White Blood Cell Count, WBC Count
Medical Term: Leukocyte Count, Automated
Summary
A blood count for leukocytes (WBC), automated is a laboratory test that measures the number of white blood cells in a blood sample. This test is performed using automated equipment to ensure accuracy and efficiency.
Purpose
This procedure is used to evaluate the body's immune system by determining the number of white blood cells. It helps in diagnosing conditions such as infections, inflammation, immune system disorders, and certain types of leukemia. The goal is to detect abnormal WBC levels that indicate underlying medical issues.
Indications
- Symptoms of infection (e.g., fever, chills)
- Signs of inflammation (e.g., swelling, redness)
- Unexplained fatigue or weakness
- Diagnosing or monitoring diseases such as leukemia
- Monitoring the immune system in patients undergoing chemotherapy or radiation therapy
Preparation
- No specific preparation is typically required.
- Patients should inform their healthcare provider of any medications they are taking as some drugs can affect WBC counts.
- Fasting is usually not necessary for this test.
Procedure Description
- A healthcare provider will clean the patient’s arm with an antiseptic.
- A tourniquet is applied to the upper arm to fill veins with blood.
- A sterile needle is inserted into a vein, and a blood sample is drawn into a tube.
- The collected blood sample is sent to a laboratory where an automated analyzer counts the white blood cells.
- Results are typically reviewed by a medical professional to determine any abnormalities.
Duration
The actual blood draw takes about 5-10 minutes. Laboratory analysis usually takes a few hours to a day, depending on the facility.
Setting
The procedure is performed in a medical laboratory, outpatient clinic, hospital, or doctor's office.
Personnel
- Phlebotomist or nurse for blood draw
- Laboratory technician for sample analysis
- Physician or medical professional for result interpretation
Risks and Complications
- Common risks: Minor pain or bruising at the needle site.
- Rare risks: Infection at the puncture site, excessive bleeding, or feeling light-headed or faint.
Benefits
- Provides crucial information about the immune system's status
- Helps in diagnosing infections, inflammations, and blood disorders
- Early detection of serious conditions based on abnormal WBC counts
- Results are typically available within hours to a day
Recovery
- Minimal recovery is needed; most patients can return to normal activities immediately.
- Patients might need to apply pressure to the puncture site to prevent bruising.
- Follow-up appointments are based on the results of the test and any underlying conditions detected.
Alternatives
- Manual White Blood Cell Count: Performed using a microscope. More time-consuming and less common in modern medicine.
- Differential Blood Count: Evaluates different types of white blood cells to provide more detailed information about the immune system.
Patient Experience
- The patient will feel a small prick when the needle is inserted.
- Mild discomfort or bruising might be experienced at the puncture site.
- Many patients report slight dizziness or light-headedness, but this is usually temporary.
- If pain persists or there are signs of infection, the patient should contact their healthcare provider.
