What is Rh factor blood grouping system?
Rh Factor is also an antigen and those who have it are called Rh+. Those who don’t have it are called Rh-. A person with Rh- blood does not have Rh antibodies naturally in the blood plasma but a person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ blood, whose Rh antigens can trigger the production of Rh antibodies. A person with Rh+ blood can receive blood from a person with Rh- blood without any problems.
