Useful For Suggests clinical disorders or settings where the test may be helpful

Determining the specific proteotype for prognosis and genetic counseling for patients with alpha-1-antitrypsin deficiency

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
A1ASZA1AT Proteotype S/Z, LC-MS/MSNoYes
AATPAlpha-1-Antitrypsin, SYes, (order AAT)Yes

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

A1APRAlpha-1-Antitrypsin Phenotype, SYes, (order A1APP)No

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

If the mass spectrometry proteotype and quantitative serum level are discordant, then phenotyping will be added and performed at an additional charge.
