This is pretty technical stuff and I can't claim to be sure, but I think this looks likely. I was beginning to get a sense that "primer"/"priming" was the term when I found this, on Zika:

"Las técnicas para identificar que hay o hubo una infección, son:
1-RT-PCR que requiere unos iniciadores ó primers y controles positivos específicos para el Zika, que actualmente utiliza CDC en sus laboratorios en Fort Collins y que actualmente, no están disponibles comercialmente."

The CDC reference is interesting, because here's what a OPS/OMS document (not yours?) says:

"Existen diferentes protocolos (iniciadores y sondas) para la detección de ZIKV por RT-PCR (tanto convencional como tiempo real). Teniendo en cuenta la sensibilidad, se recomiendan los protocolos utilizados por el centro para el Control y Prevención de Enfermedades (CDC)."

And here's the term, albeit in a different context (influenza):

"And what we have - what really is important for clinicians to know is that in order to diagnose this swine influenza virus and infection, you really need to get clinical upper respiratory tract specimens to your state health laboratory for real time PCR testing. They have the CDC primer protocol to detect influenza A and influenza B and subtypes of influenza H1H3."

And from another influenza study in the CDC's own journal, Emerging Infectious Diseases:

"The priming protocol generated significant CTL activity directed at the NP and PB2 proteins."
