How accurate are bs readings ??

[Horwendil]

This morning, and in celebration of a script for test strips, I went crazy and did two, yes two before breakfast test. One on the middle finger, and then, within a minute, one on the indexfinger.
results: middle finger 6.6, indexfinger 6.1. What does the panel think?,and what do we take as
true reading ? :?

There's a margin of error around +/- 10 to 15% for fingerprick tests, so take this into account. Try testing the same drop of blood twice and see what happens. It helps if you thoroughly wash your fingers before testing to remove contaminants.
