Blood count; reticulocyte, manual
CPT4 code
Name of the Procedure:
Blood Count; Reticulocyte, Manual (Commonly referred to as Manual Reticulocyte Count)
Summary
A Manual Reticulocyte Count is a laboratory test that measures the number of reticulocytes (immature red blood cells) in your blood. The test is typically done using a microscope after staining a blood sample. It provides important information about bone marrow function and red blood cell production.
Purpose
The main goal of this procedure is to assess the bone marrow’s ability to produce new red blood cells. It helps in diagnosing and monitoring conditions like anemia, bone marrow disorders, and the effectiveness of treatments affecting red blood cell production.
Indications
- Unexplained anemia or fatigue
- Monitoring recovery after treatments like chemotherapy
- Diagnosing bone marrow disorders
- Evaluating response to treatments for anemia
Preparation
- Generally, no special preparation is required.
- Patients might be told to inform their healthcare provider about any medications or supplements they are taking.
Procedure Description
- A blood sample is drawn from a vein in the arm using a needle and syringe.
- The blood sample is then placed on a glass slide and stained with special dyes that highlight reticulocytes.
- The slide is examined under a microscope by a laboratory technician who counts the reticulocytes manually.
- The results are calculated and reported as the percentage of reticulocytes in relation to the total number of red blood cells.
Duration
Collecting the blood sample takes only a few minutes. The entire process, including preparing the slide and counting cells, may take up to an hour in the laboratory.
Setting
The blood sample is typically collected at a hospital, outpatient clinic, or laboratory. The analysis is performed in a specialized laboratory setting.
Personnel
- Phlebotomist or nurse to draw the blood sample.
- Laboratory technician or medical technologist to perform the manual count.
Risks and Complications
- Mild pain or bruising at the needle site.
- Rarely, infection at the needle puncture site.
Benefits
- Provides critical information regarding bone marrow function.
- Helps in diagnosing and managing various hematologic conditions.
- Results are typically available within a day, allowing for quick medical decision-making.
Recovery
- No specific recovery time is needed.
- Patients can return to their usual activities immediately after the blood draw.
- Follow-up depends on the test results and the underlying condition being monitored.
Alternatives
- Automated Reticulocyte Count: Uses a machine for counting and can be quicker, but may not always be available or as detailed.
- Other blood tests or bone marrow biopsy might provide additional or comparative information.
Patient Experience
- During the blood draw, patients might feel a quick pinch.
- Mild discomfort at the needle site is possible, but typically resolves quickly.
- No significant pain or discomfort is expected after the procedure.
