we are about to test 3M coconut protein allergen as cleaning verification. it is a laminar flow device kit (LFD) - quite similar to a pregnancy test kit, w/c shows (+) or (-) to coconut protein.
lowest limit detection is 2ppm, upper limit detection is ~1.6 mg/ml or 1,600ppm.
for cleaning validation, we will run the coconut protein LFD parallel w/ 3M ATP clean trace.
target standard we would like to get:
with a (-) reading in coconut protein LFD, we shall take the corresponding ATP (RLU) reading and set that as our cleaning verification standard for ATP.
as coconut protein LFD is quite expensive, we shall retain using ATP
would you find this validation activity sound?
thanks ahead and would appreciate comments!
