Additional Tests Lists test(s) that are always performed, at an additional charge, with the initial test(s)

Test IDReporting NameAvailable SeparatelyAlways Performed
FIBRFibroblast CultureYesYes
CRYOBCryopreserve for Biochem StudiesNoYes

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

When this test is ordered, a fibroblast culture and cryopreservation for biochemical studies will always be performed at an additional charge. However, for multiple lysosomal enzyme assays on a patient utilizing fibroblast culture, only 1 culture is required regardless of the number of enzyme assays ordered. If viable cells are not obtained within 10 days, client will be notified.
