Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

A quantitative galactose-1-phosphate uridyltransferase GALT) level is used in addition to the isoelectric focusing for accurate interpretation. If recent GALT test results are not provided, GALT will be automatically performed at an additional charge. However, if previous GALT results are provided, GALT testing will be cancelled and not charged.
