Hematocrit [Volume Fraction] of Blood by Centrifugation

Active

Part Description

LP16699-8 Erythrocyte
Erythrocytes or red blood cells (RBCs) are the cells in the circulation that carry oxygen to and remove carbon dioxide from the tissues throughout the body. They are produced in the bone marrow in response to erythropoietin where they transition through six stages over a seven day period. When they are released into the circulation, their nucleus has been extruded and they measure 6-8 microns in diameter. The lifespan of RBCs is about 120 days. When the RBC ages the cell membrane becomes less pliable and tears as they cell travels through the micro vessels of the body. The damaged RBCs are removed from the circulation by the spleen. Variations in number, shape and size of RBCs are indicative of many diseases and disorders. There are many factors that may lead to decreased numbers of RBCs including hemorrhage, hemolysis, iron or vitamin deficiency, marrow failure and more. Larger than normal RBCs may be indicative of liver disease while smaller than normal RBCs are seen in thalassemias and other anemias.(Mosby's manual of diagnostic and laboratory tests, Kathleen Deska Pagana; Timothy James Pagana, Elsevier St. Louis, Mo ©2010) Source: Regenstrief LOINC

Basic Attributes

Class: HEM/BC
Type: Laboratory
First Released: Version 1.0
Last Updated: Version 2.79 (NAM)
Change Reason: Release 2.79: COMPONENT: Triggered by Coll w SCT:Hematocrit as a component is not an adequate description for a ratio, therefore Hematocrit is kept as a synonym, and the actual component is expressed as it should be:Erythrocyte/Specimen Volume;
Order vs. Observation: Both
Common Test Rank Get Info: 6416
