A delayed diagnosis of Arginase 1 Deficiency (ARG1‑D) can make it difficult to move forward1-2

ARG1‑D: A progressive, debilitating, inherited
metabolic disease3-5

Arginase 1 Deficiency (ARG1-D) is associated with the persistent
elevation of plasma arginine and, when left undiagnosed,
may lead to significant morbidity and early mortality.6-9

Arginase 1 Deficiency (ARG1-D) - order amino acid panel and genetic test

A plasma amino acid panel and genetic test
can help diagnose ARG1-D8,10

Elevated plasma arginine is the hallmark of ARG1-D.6 Order a no-charge sponsored plasma amino acid panel and genetic test to confirm a diagnosis.*
