Self-monitoring Of Blood Glucose: The Use Of The First Or The Second Drop Of Blood

Go to: Abstract There is no general agreement regarding the use of the first or second drop of blood for glucose monitoring. This study investigated whether capillary glucose concentrations, as measured in the first and second drops of blood, differed ≥10% compared with a control glucose concentration in different situations. Capillary glucose concentrations were measured in two consecutive drops of blood in the following circumstances in 123 patients with diabetes: without washing hands, after exposing the hands to fruit, after washing the fruit-exposed hands, and during application of different amounts of external pressure around the finger. The results were compared with control measurements. Not washing hands led to a difference in glucose concentration of ≥10% in the first and in the second drops of blood in 11% and 4% of the participants, respectively. In fruit-exposed fingers, these differences were found in 88% and 11% of the participants, respectively. Different external pressures led to ≥10% differences in glucose concentrations in 5–13% of the participants. We recommend washing the hands with soap and water, drying them, and using the first drop of blood for self Continue reading >>

    I've noticed recently that my UltraSmart gives me different readings depending on which finger I test on. This may sound absurd, but my right ring finger always tests about 40-50 points below my left ring finger. For instance, last night before dinner I tested five times on five different fingers and got results ranging from 190 to 287. I always wash and completely dry my hands before I test, my meter is almost new, and this is not the first time this has happened. I usually take an average of the results and use that for my correction factor. Has this happened to anyone else?

    it's strange but I have had this happening several times noone could explain to me either. I even asked the doctor and she didn't know. Maybe its like when they check your blood pressure and both arms have different results. Do you hands/fingers feel like they asleep often? If so it might have to do with that. Am sorry am not of much help just wanted to say you are not the only one this has happened to. All the best to you

    You need to keep in mind that BG meters are allowed a 20% accuracy range. Read this for more info on an experiment I conducted. http://www.diabetesforums.com/monitoring/11696-blood-glucose-meter-comparison.html
    And all 4 of those tests were done with the same sample of blood...
    Also, remember, blood takes a while to circulate through all parts of the body. Therefore one finger may get it sooner than another. Heck, even on the same finger, a different vessel may get fresh blood 5 minutes sooner than another one.
    It's just something we have to live with for now until better technology comes along. Which at this time I don't see any.
