Test information
Indications for testing
This test is indicated for individuals with tyrosinemia, on treatment, who are being monitored by their healthcare provider.
Condition description
Tyrosinemia is an inherited metabolic condition in which the body does not have the enzyme FAH needed to metabolize tyrosine. In untreated, tyrosine and its byproducts build up in tissues and organs which can lead to serious health problems. Treatment consists of a diet modifications and the use of a drug that prevents the formation of succinylacetone, the toxic agent responsible for liver and kidney damage. For patients with tyrosinemia, frequent monitoring of tyrosine and succinylacetone levels can aid in maintaining the correct dose of medication and monitoring of metabolite levels within the body.
Test methods and limitations
Tandem mass spectrometry (MS/MS) is an analysis technique that utilizes two mass analyzers to target analytes based on mass and charge. This mass filtering process provides highly sensitive and specific measurements of small molecules or peptides from biological samples.
