Term Description

This assay measures the percent of red blood cells that have complete loss of the CD59 antigen. The loss of CD59 is associated with paroxysmal nocturnal hemoglobinuria (PNH), and patients with complete loss of CD59 are more likely to have hemolysis compared to patients with partial loss of CD59.

Part Description

LP268509-9   Erythrocytes.CD59 complete loss
Paroxsmal nocturnal hemoglobinuria (PNH) is a condition that causes hemolytic anemia, bone marrow failure, and a proclivity to develop thrombosis. PNH occurs when the PIG-A gene of bone marrow stem cells undergoes mutation. Stems cells develop into erythrocytes (RBCs), white blood cells (WBCs), platelets, and mature cells that contain the PIG-A gene mutation, and as a result, lack a sufficient number of glycosylphosphatidylinositol-anchored protein (GPI-AP). The GPI-APs have various roles, some of which are to help to prevent RBC destruction, fight infection, and promote thrombosis.https://www.hopkinsmedicine.org/kimmel_cancer_center/types_cancer/paroxysmal_nocturnal_hemoglobinuria_PNH.html CD14, 16, 24, and 59 are GPI-linked proteins that are used as markers for the presence of GPI, as is fluorescent aerolysin (FLAER), which binds to GPI-APs. Patients with PNH lack sufficient GPIs and therefore have reduced expression of these cell markers and FLAER compared to patients without PNH. Patients with complete loss of CD59 are more likely to have hemolysis compared to patients with partial loss of CD59. Source: Regenstrief LOINC

Change Reason
Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component;
