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.
In the ABO Grouping System, there are four types of blood: Type A, Type B, Type AB, and Type O, which are determined by the presence or absence of certain antigens on the surface of red blood cells. According to the American Red Cross, Group A â has only the A antigen on red cells (and B antibody in the plasma).f your blood cells do not stick together when anti-A and anti-B are added, you have type O blood. In back testing, known A and B cells are added to samples. If the blood clumps together only when B cells are added, the donor has type A blood.
