The analyses conducted by PerkinElmer Genetics produce results that can be used by qualified physicians in the diagnosis of disorders described herein. Evidence of these conditions will be detected in the vast majority of affected individuals; however, due to genetic variability, age of the patient at the time of specimen collection, quality of the specimen, health status of the patient, and other variables, such conditions may not be detected in all affected patients.

1. There is a lower probability of detection of this condition during the immediate newborn period.
2. Succinylacetone (SUAC) is the primary marker for Tyrosinemia Type 1
