A Colorimetric Multimetabolite Assay for Quantitative Measurement of Keto Acids in Urine for At‐Home Monitoring of Metabolic Disorders

open access: yesJournal of Analytical Methods in Chemistry, Volume 2026, Issue 1, 2026.
Inborn errors of metabolism such as phenylketonuria (PKU) and maple syrup urine disease (MSUD) can cause severe developmental problems. Both conditions can lead to harmful levels of keto acids in biofluids—phenylpyruvic acid (PPA) in PKU and branched‐chain α‐keto acids in MSUD. Monitoring urinary keto acids helps track dietary adherence and reduces the
