Aminoaciduria – Definition & Meaning

Aminoaciduria is a medical term that refers to the presence of amino acids in urine.

Aminoaciduria can be diagnosed through a urine test, which measures the levels of amino acids in the urine.


The term aminoaciduria is derived from the Greek words “amino” (meaning “nitrogen-containing”) and “ouron” (meaning “urine”). The condition was first described in the medical literature in the early 20th century, and has since been the subject of extensive research.
