Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

Hemoglobin electrophoresis cascade will always include hemoglobin A(2) and F and hemoglobin electrophoresis.

 

Reflex testing-Hemoglobin electrophoresis reflex testing, performed at additional charge, may include any or all of the following as indicated to identify rare hemoglobin variants present: hemoglobin S screen, unstable hemoglobin, isoelectric focusing confirms, hemoglobin variant by mass spectrometry, hemoglobin F red cell distribution, beta-globin gene, large deletion/duplication, alpha-globin gene sequencing, and beta-globin gene sequencing.

Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
