French term

point de virage

French to English Medical Medical (general) pharma
Hello everyone,

This is in a set of results of a CSF analysis. For each analyte, the test method is given.

So:
Proteins - Photométrie-lecture au point de virage (Advia 1800)
Glucose - Photométrie-lecture en point final (Advia 1800)

When I look up the Advia 1800, the assay methods given are: Endpoint, rate reaction, 2-point rate, multipoint homogeneous immunoassay.

If "lecture en point final" is "endpoint reading," what then is "lecture au point de virage"?

Thank you!

Le point de virage est en fait une zone de virage qui peut s'étaler sur une zone de pH (pour les réactions acido-basiques).
Point final
Anglais : final point
Espagnol : punto final
En titrimétrie, point d'un titrage où la réaction de titrage semble s'achever d'après le système d'indication, par exemple d'après le virage d'un indicateur coloré ou d'après la réponse d'une méthode instrumentale. En général, il diffère légèrement du point équivalent.

La différence des volumes de solution titrante ajoutés aux deux points (équivalent, final) constitue l'erreur absolue de titrage.

I just saw that granddictionnaire.com gives "endpoint" for "point de virage."
