## Abstract __N__‐acetylaspartic acid (NAA) is a specific urinary marker for Canavan disease, an autosomal recessive leukodystrophy. We developed a ‘dilute and shoot’ stable isotope dilution liquid chromatography tandem mass spectrometry (LC‐MS/MS) method for determination of NAA in urine. Deuterat
