    Possibly useful anecdote: My insurer gave me a Livongo glucose monitor and supplies. I became skeptical of the monior because it was giving me values **much** higher than my previous monitor. So I tested its performance against both the monitor I had been using and (b) capillary blood draws taken within 10 minutes of fingertips draws using the Livongo monitor. Result: The Livongo monior was systematically biased. (To be sure, all glucose monitors are overly precise, reporting three sighnificant digits when at best the second digit is meaningful.)

    I called them to discuss, maybe get a replacement, on the sensible theory that they would not want customers using a bad monitor. They expressed no interest in the problem. I notified my insurer of the problem and advised them to stop providing it.
