Help with BS testing

should I test after food or before food. It raises after my cat eats and I don't know which reading I should be using to determine Insulin dosage. Tks

 

Hi. The order is 1) Test, 2) Feed, 3) Give shot. You do not want your pre-shot test result to be impacted by food, so withhold food for two hours before.

 

Hi, so are you saying the BG Level I should use for insulin dosage needs to be Before food?

 

Yes, that's correct. You also need to know how low a dose of insulin drops the BG so we recommend a test near the nadir. That's the time of peak insulin action where BG should be lowest and it generally falls 5 to 7 hours after the shot.
