Blood sorts are decided by antigens — a substance that triggers an immune response — on the floor of purple blood cells. There are ABO antigens, which designate ABO blood sorts. That is decided by the ABO gene. For instance:

Methods to discover your blood kind?
Here is three essential methods to kind your blood:
- Have your physician do a blood check
- Donate blood
- Use an at-home blood check
1. Scientific check
One of many best and handiest methods to find out your blood kind is to have your physician carry out a check. An expert will draw blood after which carry out two assessments on the blood pattern: ahead typing and reverse typing.
Throughout ahead typing, the blood pattern is combined with antibodies towards kind A and B blood. Based mostly on whether or not the blood cells stick collectively when combined with the antibodies, your blood kind will be decided from there. In case your blood cells stick collectively when combined with antibodies towards kind B blood, you’ve gotten kind B blood. In case your blood cells stick collectively when combined with antibodies towards kind A blood, you’ve gotten kind A blood.
To verify the end result, the following step is reverse typing, that means the blood pattern with out purple blood cells — known as a serum — is combined with kind A and sort B blood cells. Kind A blood could have antibodies towards Kind B blood within the pattern and sort B blood could have antibodies towards Kind A blood. Kind O blood will include antibodies towards Kind A and Kind B. So, if sticking happens when the serum is combined with kind B blood cells, you’ve gotten kind A blood, and if sticking happens when the serum is combined with kind A blood cells, you’ve gotten 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 coated by insurance coverage.
2. Donate blood
