Waltham, MA (PRWEB) March 06, 2012
A recently published study evaluated the accuracy of 20 different blood glucose meters on samples with abnormal hematocrit levels. The study shows Nova Diabetes Care glucose meters, including Nova Max Plus and Nova Max Link, to be more accurate than other leading brands on samples that have abnormal hematocrit levels ranging from 25-60%.1 The study confirms findings of another study published in November 2011, showing Nova Max Plus to be the most accurate among five other glucose meter brands when testing blood with abnormally low levels of hematocrit.2
Abnormally low levels of hematocrit (medical term: anemia) occur in approximately 25% of people with diabetes and are a leading cause of inaccuracy for most glucose meters. 3,4,5 Most glucose meters assume blood samples have a normal level of hematocrit. If a person’s hematocrit is lower than normal (anemia), glucose readings can be erroneously high, increasing the risk of undetected hypoglycemia or mis-dosing of insulin. Two groups in particular frequently exhibit lower than normal adult hematocrit levels: children and the elderly. Low hematocrit levels are also associated with diabetes complicated by kidney disease, pregnancy or heart disease.6
In this study presented at the February, 2012 Advanced Technologies and Treatment for Diabetes International Meeting, 20 glucose meters were evaluated for hematocrit interference. The comprehensive study incorporated blood samples ranging from 90 to 350 mg/dL glucose and hematocrit levels ranging from 25-60%. Only 7 glucose meters met the investigators criteria for satisfactory hematocrit performance. Four of the seven were glucose meters produced by Nova including Nova Max Plus, Nova Max Link and Nova meters sold internationally under the brands Glucomen LX and GlucoFix Mio.
