Description
Direct matching – cross matching of 1 pint of blood (cross matching of 1pint.) For blood screen
Sample Type:Serum
Tests Included:
Compatibility testing between donor and recipient blood samples.
Sample Required:
Blood samples from both the donor and recipient.
Test Time:
Results are typically available within a few hours to a day.
What is the test?
The crossmatch or compatibility test involves mixing a small amount of donor blood with recipient blood to check for any reactions that could occur during a blood transfusion.
Test Procedure:
Blood samples from the donor and recipient are mixed and observed for any signs of incompatibility, such as clumping or agglutination.
When to take the test:
Before a blood transfusion to ensure compatibility between donor and recipient blood.

Frequently Asked Questions (FAQs) for Cross Matching of 1 Pint of Blood:
Q1: Why is cross matching important before a blood transfusion?
A: Cross matching ensures compatibility between donor and recipient blood to prevent adverse reactions during transfusion.
Q2: What happens if there’s a positive crossmatch?
A: A positive crossmatch indicates incompatibility, and the blood may not be suitable for transfusion to the recipient.
Q3: How long does the crossmatch process take?
A: The process usually takes a few hours to a day, depending on the laboratory and urgency of the transfusion.
Q4: Can cross matching detect all potential transfusion reactions?
A: Cross matching helps prevent immediate transfusion reactions but may not detect all potential complications that could occur later.
Q5: Are there any risks associated with cross matching?
A: Cross matching is a standard procedure with minimal risks, but rare complications can include sample mix-ups or errors in testing.
