The Phenylalanine (PA) test measures the level of this essential amino acid in the blood. It's crucial for detecting phenylketonuria (PKU), a rare genetic disorder that can cause intellectual disability if left untreated. PA is also important for the production of other amino acids and neurotransmitters. This test is part of newborn screening programs and can be used to monitor individuals with known PKU or other metabolic disorders. Elevated levels may indicate PKU, liver disease, or other metabolic issues, while low levels might suggest malnutrition or certain genetic conditions.
A low phenylalanine level may indicate:
Low levels can lead to confusion, depression, memory problems, and reduced alertness. It’s important to consult with a healthcare provider to determine the underlying cause and appropriate treatment.
Elevated phenylalanine levels may indicate:
High levels can lead to intellectual disability, seizures, behavioral problems, and other neurological issues if left untreated, especially in infants and young children. Immediate medical attention is crucial to prevent potential complications and determine appropriate management strategies.
