Hi,
I’m working with a limit test to prove the absence of protein in my samples. It’s a simple limit test, my standard is my LOD - it’s a yes or no result. The method has been validated (specificity and LOD), but I’d like to show sample / buffer stability, so we don’t need to prepare everything freshly. And here I’m kind of lost - since I don’t get any ‘real’ results - we don’t quantify anything - I cannot compare two measurements (fresh sample buffer vs ols sample buffer) - both measurements would just show the samples are below LOD (I guess). What would be the best way to prove that my buffer solutions are safe to store for a few weeks, i.e. give the same results as fresh buffers?
Any help with that matter is greatly appreciated, thanks in advance!
Best,
