Les lecteurs qui necessitent des gouttes de sang de faible volume proposent une mesure a partir d’une goutte de sang prelevee sur site alternatif, (base du pouce, avant-bras, bras, cuisse, mollet). Mais les manuels des lecteurs de glycemie precise que lorsque la glycemie varie, la variation est beaucoup plus tardive dans la couche la plus superficielle de la peau que dans les couches profondes de la peau. Si tel n’est pas le cas, il est preferable de realiser le prelevement au bout des doigts. Alternate site refers to testing blood glucose on parts of the body other than the fingertip: most commonly the forearm, palm or thigh.
Testing somewhere other than the finger may bring a sigh of relief to many people with diabetes. With all meters, routine testing on an unrubbed forearm, upper arm, thigh or calf gives a test result that is 20 to 30 minutes old. On the other hand, lagging test sites such as the forearm or thigh tell you what your blood glucose was around 20 to 35 minutes ago - not what it is right now. Several monitoring companies give people the choice to test their blood glucose using alternative sites.

A device that clips on to the ear could signal the end of painful blood tests for thousands of diabetics.
Diabetes develops when the pancreas stops or reduces its output of insulin, the hormone that helps us get energy from the food we eat. To work out how much insulin they need, many sufferers have to prick their fingers up to four times a day to test glucose levels. Once the clip is placed on the ear, tiny sensors use a combination of sound waves and heat measurement to gauge glucose levels by firing signals through the blood inside the earlobe. Ultrasound can measure levels of glucose because sound waves are transmitted through the tissue in the earlobe at different rates, according to how much glucose is present. The ear clip device also fires low-level electromagnetic waves into the tissue - these are transmitted differently depending on blood sugar.
Though none of these three methods is accurate enough on its own to replace blood tests, by averaging out scores GlucoTrack can come up with a valid reading. The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline.
That difference can be crucial if your blood glucose is dropping fast --- a forearm test might tell you that the level is fine, because the forearm is a lagging test site, while a fingertip test correctly alerts you to a low number.

However, lagging test sites such as the forearm or thigh are only reliable when your blood glucose levels are relatively stable, such as fasting blood glucose. With a little bit of education, you can give your fingertips a rest and maybe test more often than you do now. This site contains detailed information about blood glucose monitoring, insulin injection and safe sharps disposal. Heat also travels at a different rate through tissue when blood glucose levels are high or low.
Because of this, lagging test sites cannot replace the fingertip or palm completely for any person.
Interactive quizzes, educational literature downloads and animated demonstrations help to teach diabetes care skills. Just remember: any time you want to be sure of an accurate, up-to-date blood glucose reading, test on your fingertip or palm.
