Grifols has launched in the US its AlphaID At Home over-the-counter genetic test for alpha-1-antitrypsin deficiency (alpha-1), a protein deficiency that can result in chronic obstructive pulmonary disease. The firm is providing for free its PCR-based AAT test that uses cheek swab samples and laboratory testing to identify 14 genetic variants in the serpin peptidase inhibitor class A member 1 (SERPINA1) gene. The firm received US Food and Drug Administration 510(k) clearance for the test in November 2022.
