Compatibility test each unit; immediate spin technique
CPT4 code
Name of the Procedure:
Compatibility Test Each Unit; Immediate Spin Technique
Summary
The Compatibility Test Each Unit; Immediate Spin Technique is a blood test performed to ensure that a donor's blood is compatible with the recipient's blood. This procedure is crucial in preventing adverse reactions during blood transfusions.
Purpose
The primary purpose is to detect any immediate incompatibility between donor and recipient blood that could lead to a transfusion reaction. The goal is to ensure safe blood transfusions by confirming that the blood types are a suitable match.
Indications
- Patients in need of a blood transfusion.
- Patients undergoing surgery with potential blood loss.
- Individuals with anemia or blood disorders requiring transfusions.
- Patients with trauma or injury resulting in significant blood loss.
Preparation
- No special preparation like fasting is typically necessary.
- Healthcare providers will review the patient's medical history and any previous transfusion reactions.
- Blood samples from both the donor and the recipient will be collected.
Procedure Description
- Blood Collection: Blood samples are taken from the donor unit and recipient.
- Mixing: The recipient's serum and donor's red cells are mixed in a test tube.
- Immediate Spin: The mixture is spun rapidly in a centrifuge to facilitate the interaction.
Observation: The sample is observed for any agglutination (clumping) which indicates incompatibility.
- Equipment Used: Test tubes, centrifuge, pipettes.
- Anesthesia: None required, as this is a laboratory test.
Duration
The procedure typically takes around 10 to 15 minutes to complete.
Setting
The test is usually conducted in a hospital laboratory or blood bank.
Personnel
- Medical laboratory technologists
- Blood bank technologists
Risks and Complications
- Common Risks: Minimal risks since it is a laboratory test.
- Rare Risks: Inaccurate test results due to sample handling errors or rare blood type incompatibility not detected by the immediate spin technique.
Benefits
- Ensures transfusion safety.
- Prevents serious transfusion reactions.
- Immediate results facilitate timely blood transfusions.
Recovery
- No recovery needed as it is a non-invasive laboratory test.
- Follow any additional instructions provided by the healthcare team regarding transfusion procedures.
Alternatives
- Coombs Test: More comprehensive but takes longer; detects antibodies that might cause delayed transfusion reactions.
- Electronic Crossmatching: Uses computer systems to verify compatibility; faster but requires extensive donor database and technology.
Patient Experience
- The patient will experience minimal discomfort limited to the blood draw.
- No significant pain or discomfort is involved post-procedure.
- Routine comfort measures include a small bandage at the draw site.
