Clinical Use
Order TestUse
Amino acid analysis is necessary for the diagnosis of a variety of inborn errors of metabolism (e.g., phenylketonuria, tyrosinemia, citrullinemia, non‑ketotic hyperglycinemia, maple syrup urine disease, homocystinuria). It is also important for monitoring treatment plans for these disorders and assessing nutritional status. The methodology is highly accurate at very low and elevated levels.
