Chương 405: The First Silent Treatment (5)

"It can't be wrong, it's type B blood. We have inventory for the other blood types. We're only lacking blood type B because there had been a large demand recently."

Huo Mian felt her mind going blank. Not knowing what to think, she pulled back her arm.

She never paid much attention to her mother's blood type and assumed that she was either type A or AB.

She was confident that she was type AB since she had multiple tests done in the past.

The last time she went to the hospital to visit Huo Zhenghai, she had checked his patient profile and was sure that he was blood type B.

So it had to mean that her mother was either type A or AB blood.

To have an AB type kid, if one of the parents was type B, then the other one had to be either A or AB type.

If both parents were blood type B, then the child would either have type B or O blood, meaning that having a child with AB type blood was impossible.
