Homogentisate

Homogentisate is an organic compound that appears in urine when your body breaks down certain amino acids. Elevated urinary homogentisate typically indicates alkaptonuria, a rare inherited metabolic disorder. In this condition, the enzyme responsible for breaking down homogentisate is deficient, causing accumulation. Alkaptonuria can lead to dark urine, darkening of connective tissues, and arthritis if undiagnosed. Early detection through this test allows for dietary management and monitoring to slow disease progression.
