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.
Two main antigen groups are used for a tissue type test. Class I has three classes of antigens (HLA-A, HLA-B, HLA-C) that are found on some kinds of blood cells. Class II has one class of antigens (HLA-D) that are found only on certain cells in the body.There are many different types of antigens in each category. tissue type test is done to: 1  See if the antigen pattern for donated tissue or organs (including a blood platelet transfusion or bone marrow transplant) is a match. 2  See how likely two people are related. 3  Find people who may have a high chance of certain autoimmune diseases.
