Reconciliation of the general ledger to sub-ledgers is another type we will review. The general ledger (or simply ledger or G/L) is a collection of all balance sheet and income statement accounts. The general ledger also includes all journal entries posted to accounts.
Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). Blood group A individuals have the A antigen on the surface of their RBCs, and blood serum containing IgM antibodies against the B antigen. 2  Therefore, a group A individual can receive blood only from individuals of groups A or O (with A being preferable), and can donate blood to individuals with type A or AB.
Human blood is typed by certain markers (called antigens) on the surface of red blood cells. Blood type may also be done to see if two people are likely to be blood relatives. The most important antigens are blood group antigens (ABO) and the Rh antigen, which is either present (positive, +) or absent (negative, -). So the two most common blood type tests are the ABO and Rh tests. The ABO test shows that people have one of four blood types: A, B, AB, or O. If your red blood cells have: The A antigen, you have type A blood. The liquid portion of your blood (plasma) has antibodies that attack type B blood.
