Term Description

This test measures the leucine level in patients who have been diagnosed with maple syrup urine disease are on a therapeutic diet for their condition. Depending on the lab, the leucine level may be used in combination with levels of other amino acids such as isoleucine, alloisoleucine, and valine to monitor the patient's progress.

Part Descriptions

LP15699-9   Leucine
Leucine, an essential amino acid isomeric with isoleucine, is the most common amino acid found in proteins. It is required for optimal growth in infancy and childhood and for nitrogen equilibrium in adults. It is also involved in maintaining muscles mass by equalizing synthesis and breakdown of proteins. The major food sources of leucine are whole grains, milk and milk products, eggs, meat, soy beans, and leafy vegetables. Leucine toxicity, as seen in decompensated Maple Syrup Urine Disease (MSUD), causes delirium and neurologic compromise, and can be life-threatening.
