German term or phrase: Identitätsreaktion
In einer Produktbeschreibung steht:
Prüfung auf Identität
Die Lösung gibt die Identitätsreaktion b auf Phosphat (V.3.1.1).

Wie könnte man "Identitätsreaktion" übersetzen?

Vielen Dank im voraus.

About The Immunodiffusion Test
Immunodiffusion is a qualitative or semi-quantitative test based on the principles of double diffusion described by Oudin and Ouchterlony. An antibody and its homologous soluble antigen are placed in separate wells cut in a suitable diffusion medium (agarose or CleargelTM) and allowed to diffuse outward into the medium. Between the two wells, a concentration gradient of each of the reaction components is established ranging from antigen excess closest to the antigen well, to antibody excess closest to the antibody well. A visible line of precipitate forms at the point of equivalence.

definition of identity reaction:

A chemical reaction whose products are chemically identical with the reactants, for example the bimolecular self exchange reaction of CH3I with I-. See also degenerate rearrangement.

agree  Ramey Rieger (X): ours is BUT to reason why....

  -> thanks Ramey and indeed :)
disagree  Cilian O'Tuama: doubt it very much - sounds more like a solution for detecting/proving the presence of PO4. Identity reaction (whose products are chemically identical with the reactants) is completely different. Chemistry can be a minefield, best not dabbled in!

Explanation:
Brit. Ph. and U.S. Ph. both use the term "Identification B" when it's used as a heading.
Seeing as it's being used in a sentence here, I'd suggest sth. like "solution is used in identification test B for phosphate.

Hello Therese,
I think I'll be less inclined to try to help next time.

Would you mind sharing the answer you "found elsewhere". It would interest me, and maybe others too.

Thanks,
Cilian
