85013 Blood count; spun microhematocrit

Name of the Procedure:

Blood count; spun microhematocrit

Summary

The spun microhematocrit is a common laboratory blood test that measures the proportion of red blood cells in your blood. By spinning the blood sample in a centrifuge, the red blood cells are separated from the plasma, allowing the hematocrit value to be determined.

Purpose

This procedure helps diagnose and monitor conditions like anemia, dehydration, and other disorders that affect the proportion of red blood cells in the blood. The goal is to provide a quick and accurate measurement of red blood cell concentration to assist in medical decision-making.

Indications

• Symptoms such as fatigue, weakness, and shortness of breath that may suggest anemia
• Conditions like bleeding disorders, chronic diseases, or ongoing chemotherapy
• Assessment of hydration status in patients with severe vomiting or diarrhea

Preparation

Generally, no special preparation is required for a spun microhematocrit test. Patients may be advised to avoid heavy meals or certain medications before the test, depending on specific healthcare provider instructions.

Procedure Description

1. A small blood sample is drawn from a vein in your arm or via fingerstick.
2. The blood sample is placed in a small capillary tube.
3. The tube is sealed and placed in a centrifuge, a machine that spins the sample at high speed.
4. The centrifuge separates the blood into layers, with red blood cells at the bottom.
5. The proportion of the tube occupied by red blood cells is measured to determine the hematocrit value.

Duration

The procedure itself is quick, typically taking around 5-10 minutes, including blood draw and centrifugation.

Setting

The procedure is performed in a laboratory setting, which may be part of a hospital, outpatient clinic, or specialized diagnostic center.

Personnel

• Laboratory technicians or phlebotomists for blood sample collection and handling.
• Supervising medical technologists or pathologists for result interpretation and reporting.

Risks and Complications

• Minor pain or discomfort at the blood draw site
• Slight risk of bruising, bleeding, or infection at the puncture site
• Rarely, patients may feel dizzy or faint

Benefits

• Quick and reliable results
• Minimal discomfort
• Provides valuable information to diagnose and manage various health conditions
• Immediate feedback for hydration and red blood cell status

Recovery

• No significant recovery period is needed.
• Patients can resume normal activities immediately after the procedure.
• Follow any specific recommendations by the healthcare provider if additional tests are required.

Alternatives

• Complete Blood Count (CBC), which provides a comprehensive analysis of blood components.

• Automated hematocrit measurement using hematology analyzers.

  Pros: More detailed information with CBC; more comprehensive.

  Cons: Typically more expensive and may take longer to get results back compared to the spun microhematocrit.

Patient Experience

Patients typically experience minimal discomfort during the blood draw. The sensation is similar to any standard blood test, with a quick needle prick. Slight bruising or soreness at the site may occur but usually resolves quickly. Upon spinning, the patient generally doesn't feel anything and can wait comfortably for the results. Pain management measures include the option of local anesthesia for very sensitive patients or children, though it is rarely necessary.
