Question

56-year-old patient has been in a construction accident. He has lost a lot of blood and requires a blood transfusion. The patient's blood type is unknown, so a blood test is performed. The results show blood clotting when the Anti-A serum and Anti-Rh serum are added to the blood sample.

Based on the information presented, which blood types can the hospital give this patient? Explain your reasoning.

Answer 1

Based on the information presented, the hospital can give the patient either O positive or O negative blood types.

Step-by-step explanation:

The patient's blood has been shown to clot when anti-A and anti-Rh serum were added, indicating that the patient does not have the A or Rh blood group proteins present on their red blood cells. This reduces the possible blood types to either O positive or O negative.

The hospital should also screen for additional blood group antibodies to determine if there are any other incompatible blood group proteins present on the patient's red blood cells. If further testing reveals more incompatible blood group proteins, the pool of available donor blood groups will be reduced further.
