Every person has a certain blood type. There are four major blood groups: A, B, O, and AB.

In addition to these four groups, each group contains a protein termed Rh factor, which can be present (+) or absent (-). This categorizes blood groups into eight different types:

  • A+
  • A-
  • B+
  • B-
  • O+
  • O-
  • AB+
