Example POSITIVE Test Result Report

Sent to the ordering Provider within two weeks.


Includes the number of amines tested and the method of analysis.

Result Summary

This patient’s result is POSITIVE, which indicates the patient has at least one metabolic subtype (metabotype) associated with ASD. This section may include additional findings about individual amine levels.
Note: The positive or negative result is based on algorithmic analysis that compares certain amines levels to each other.


For this patient, follow-up with neurodevelopmental specialist is recommended. We also recommend researching the recommendations in the references and/or referring your patient to a metabolic specialist for further evaluation.
