Scientific Studies

Independent, peer-reviewed research on urinary tyrosine metabolism and its association with various health conditions.

Important These publications are provided for scientific reference only. CCI Reagent is an orientational tyrosine screening aid, not a diagnostic test. A positive result does not indicate cancer or any specific disease and must be assessed by a healthcare professional.
