Can a A- tive blood group donate her lungs to the patient having AB-tive groip?

Yes, a person with A-negative blood group can donate their lungs to a patient with AB-negative blood group. This is because the AB-negative blood group is a universal recipient, which means that it can receive blood from any blood type without having a negative reaction. The A-negative blood group, on the other hand, is only compatible with A-negative and AB-negative blood types. Therefore, a person with A-negative blood group can safely donate their lungs to a patient with AB-negative blood group without any risk of rejection.
