Have you ever attempted to solve a problem that doesn't exist?

I had this experience this week. My client had a "problem" with low immunity values among calves. They had an unexpected drop in blood serum total protein readings. 

They are quite consistent in drawing blood at approximately the same time each day. Samples always are allowed to sit undisturbed for about 24 hours before the same person uses the farm's clinical refractometer to assess BSTP values.
