In a high or low way ?I always wash my hands with a soap and warm water, and completely dry my hands just before testing. I noticed test results from unwashed fingertips differ significantly from washed hands test results.
To me it seems a tiny bit of sweat on our (or mine) fingertips is enough to alter readings. Alcohol too even when is dried up alters test result.
Lower from alcohol. If fingertips aren't bone dry after alcohol, the difference is about 30-40% lower. With dried up alcohol it's less. 12 points difference isn't that much.In a high or low way ?
We all know sometimes we get a real gusher finger stick so one time I tested the same drop twice and it was a 12 point difference.
I am going to make a thread meter accuracy but I am still curious hand-wash/alcohol makes yours higher or lower ?
