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

In case your blood cells stick collectively when blended with antibodies towards kind B blood, you’ve kind B blood. In case your blood cells stick collectively when blended with antibodies towards kind A blood, you’ve kind A blood.

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

I like to recommend calling your physician’s workplace to see what a blood kind check prices out-of-pocket and if it is lined by insurance coverage.
