Brief summary
The goal of this observational study is to evaluate the performance of the PheCheck™ test for the rapid detection of phenylalanine (Phe) from a fingerstick sample, in patients 1 year or older with phenylketonuria (PKU) or hyperphenylalaninemia. The main objective is comparing the concentration of phenylalanine (Phe) in capillary blood with the reference method (DBS).
Detailed description
The primary objective of this study is to evaluate the performance of the PheCheck™ test for the rapid, quantitative detection of phenylalanine (Phe) direct from a capillary (fingerstick) sample. Results will be compared to reference testing from Dried Blood Spot Cards (DBS). The PheCheck™ test performs a quantitative determination of phenylalanine in a self-collected or parent/guardian-collected capillary blood sample. The analysis will evaluate the performance of the analyte concentration of phenylalanine in prospectively collected samples self-collected and tested by patients with PKU, measured by the PheCheck™ test as compared to the standard of care DBS testing performed by a reference lab
Interventions
DEVICEPheCheck
Quantitative, single-use, rapid test Intended for home-based self-testing and monitoring of PKU. 1 fingerstick specimen collected at each study visit Sample read using an electronic reader. Results available within 1 hour
DIAGNOSTIC_TESTDried Blood Spot Cards.
Laboratory-based reference method 1 fingerstick specimen at each study visit to collect 5 samples to fill 5 spots on the card. Card sent to a laboratory, results available within 72 hours

| Performance of the PheCheck™ test for the detection of phenylalanine (Phe) concentration from capillary blood as compared to the reference method (DBS) | Day 1 | The primary objective of this study is to evaluate the performance of the PheCheck™ (Aptatek Biosciences) test for the rapid, quantitative detection of phenylalanine (Phe) direct from a capillary (fingerstick) sample. PheCheck™ is a self-test to be performed by PKU patients. Results will be compared to reference testing from Dried Blood Spot Cards (DBS) tested in a designated reference laboratory. Phe results will be blinded to the study participant |
