Human Glucometer and glucose measurements
|
LM
Hello group! I am drawing venous blood and using a human glucometer. If I understand right this is giving me results in mg/dL. Do I remember right that normal levels should range between 80-110? Is there a need and way to convert that to mmol? Thanks very much! |

There's no need to conver to mmol but to do it multiply by 18.
Here's a link to some issues with glucometers: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC360303 Standards for accuracy are pretty lax (within 15 to 20% error) and not all glucometers even meet those: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3570840/ Although some are very close: http://emj.bmj.com/content/emermed/22/3/177.full.pdf Normal nonfasting glucose on an IR diet should not be over 100 and 80s or 90s is where most lie. -- Eleanor in PA www.drkellon.com |

Here is a glucometer comparison chart from 2016
http://integrateddiabetes.com/wp-content/uploads/2016/09/meter-accuracy-Sept-2016.pdf and a comparison study from 2016 Journal of Diabetes and Science http://sites.bu.edu/bionicpancreas/files/2016/11/Comparative-Accuracy-Meters-Ekhlaspour-J-Diabetes-Sci-Technol-2016.pdf I usually tell my human diabetic patients (I am a clinical pharmacist) "if its under 120 mg/dl you can probably rely on that +/- 10 mg/dl" (so a reading of 100 is actually 90-110) Currently, I am trying to time a glucometer BS with a lab BS to compare results for my mare. The lab sample must be spun and separated fairly quickly (<90 min) or the glucose result from the lab will be falsely low. In my personal experience in a human hospital setting - even when the on-site lab tests multiple samples the BS can have a wide variety of numbers for just one patient. It's a very small snapshot in time. -- Eva and Anske October 2017 Corvallis OR Case History Anske 9yo Friesian Mare https://ecir.groups.io/g/CaseHistory/files/Eva%20and%20Anske |

Thanks Eva for the reply and links. :) I did several with variables and repeats, it does seem to be just that a snapshot and not exact.

Thanks Dr. Kellon for how to convert in case needed ( keep in notes ) and for links. The first time, I drew, took to friends office that is human dr and used one of their glucometer. McKesson True MetrixPro. I got a 63 ( yikes I thought ) but I read in another post about the RBCs metabolizing the sugar rather quickly. Took glucometer to farm, drew, tried a couple different ways and got a variety of readings but was more consistently getting low 80s when closest to draw and least time exposed to air.and light. Does that sound typical? |
