You have two changes at once here. You cannot attribute anything until one of them moves. Tolerance was my main issue with an import rule change too.

Reference ranges differ between labs, so comparing two reports is close to meaningless.

Photograph everything.

How long before you can reasonably say something is or is not doing anything?
