Someone will correct me if I'm wrong but I'm guessing it's a standard lab testing form that covers all sorts of blood tests as well as worm counting, and the figures give the normal range - if you were getting bloods etc done the results would show in the 'result' column ...
It is just a blood test result sheet for things like packed cell volume, and the prevalence of different types of white blood cell (they indicate different problems), etc.
