Spanish to English Science Medical: Pharmaceuticals

Hello all! I am working on a set of Mexican pharmaceutical documents, all part of a process validation report. Below is the (very specific) context in which the term appears. I should that the parentheses in the title seem to denote section, since other documents have names like "Reporte de Validación de Proceso (Plan de Muestreo)" or "Reporte de Validación de Proceso (Requisitos de Validación)," so I assume that the same is true with "Reporte de Validación de Proceso (Previos)."

I hope this helps. Thanks for your attention!
