During ahead typing, the blood pattern is blended with antibodies towards kind A and B blood.

If your blood cells stick collectively when blended with antibodies towards kind B blood, you’ve gotten kind B blood. If your blood cells stick collectively when blended with antibodies towards kind A blood, you’ve gotten kind A blood.
To verify the consequence, the following step is reverse typing, that means the blood pattern with out purple blood cells — referred to as a serum — is blended with kind A and sort B blood cells. Type A blood may have antibodies towards Type B blood within the pattern and sort B blood may have antibodies towards Type A blood. Type O blood will comprise antibodies towards Type A and Type B. So, if sticking happens when the serum is blended with kind B blood cells, you’ve gotten kind A blood, and if sticking happens when the serum is blended with kind A blood cells, you’ve gotten kind B blood.
