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.
ABO blood group antigens present on red blood cells and IgM antibodies present in the serum. The ABO blood group system is the most important blood type system (or blood group system) in human blood transfusion.nti-A and anti-B antibodies are usually IgM type, which are not able to pass through the placenta to the fetal blood circulation. O-type individuals can produce IgG-type ABO antibodies. The precursor to the ABO blood group antigens, present in people of all common blood types, is called the H antigen.
