Part Description

LP14574-5   Polychromasia
Polychromasia occurs when there is an abnormally high number of red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow. Polychromatophilic red cells are larger and younger than mature red cells and appear blue-gray on a blood smear. Polychromasia is usually a sign of bone marrow stress due to blood loss or other conditions. Source: Regenstrief LOINC

Reference Information

Type Source Reference
Mapping Guidance Regenstrief Help Most laboratories will report such findings as answers in their RBC morphology term [LOINC: 6742-1]. Others will report each observed finding as a separate variable, such as this one, and assign values of 1+, 2+, 3+. Mapper’s Guide for the Top 2000 plus LOINC Laboratory Observations
