CPT® Code 86906

The CPT® Code 86906 refers to a specific laboratory test known as blood typing, serologic; Rh phenotyping, complete. This procedure is essential in determining the Rh factor, which is a significant component of blood typing. The Rh factor indicates the presence or absence of the Rh antigen on the surface of red blood cells. A positive result means that the Rh antigen is present, while a negative result indicates its absence. This test is crucial for ensuring safe blood transfusions and managing pregnancies, as the Rh factor can lead to complications if an Rh-negative individual receives Rh-positive blood or if an Rh-negative mother carries an Rh-positive fetus. The complete Rh phenotyping process involves a series of serologic tests that confirm the presence of Rh antibodies in a unit of blood, thereby providing vital information for transfusion compatibility and maternal-fetal health considerations.
