Ch 5 ABO Blood Group Quiz

According to Landsteiner's Law, is an individual's red cells do not react with anti-A or anti-B, what antibodies will be present in their serum?

anti-A and anti-B

Choose the correct statement regarding the subgroups of A

sometimes react with anti-A,B but not with anti-A1 in the forward type

A presurgical patient has been tested to determine his blood group in case a transfusion is necessary during surgery. The following results were obtained: anti-A 4+; anti-B 0; anti-A,B 4+; A cells 2+, B cells 4+. What would you suspect?

the patient may have a sepsis resulting in an acquired antigen
