Who needs phenylalanine analyses of blood-spot?

1. Individuals with suspected or diagnosed phenylketonuria (PKU): PKU is a genetic disorder characterized by the body's inability to properly metabolize the amino acid phenylalanine. Phenylalanine analyses of blood-spot are often used to monitor phenylalanine levels in individuals with PKU, helping to guide dietary management and treatment.
2. Newborns as part of newborn screening programs: Many countries have implemented newborn screening programs to detect certain disorders, including PKU. Phenylalanine analyses of blood-spot are often included in these programs, allowing for early detection and intervention in affected infants.
3. Pregnant women: Phenylalanine analyses of blood-spot may be recommended for pregnant women with a known history of PKU or for those who have a partner with PKU. Maintaining appropriate phenylalanine levels during pregnancy is crucial to prevent complications and ensure the healthy development of the fetus.
4. Individuals at risk for certain neurodevelopmental disorders: Elevated levels of phenylalanine can have neurotoxic effects, potentially leading to cognitive and behavioral impairments. Therefore, phenylalanine analyses of blood-spot may be indicated for individuals at risk for certain neurodevelopmental disorders, such as autism spectrum disorder.

In conclusion, phenylalanine analyses of blood-spot are essential for individuals with suspected or diagnosed PKU, as well as for newborns, pregnant women, and individuals at risk for certain neurodevelopmental disorders.
