The most commonly ordered routine blood tests would not detect it, but Rh null people are known to have anemia and abnormal red cell shapes, so it's possible a routine CBC would show anemia and might lead to some further investigation that would eventually lead to the answer.blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma; blood group AB – has both A and B antigens, but no antibodies; Blood group O is the most common blood group. Almost half of the UK population (around 48%) has blood group O. Receiving blood from the wrong ABO group can be life-threatening.
