We studied changes in the serum fructosamine (FRA) levels with aging in 127 non-diabetic children whose ages ranged from 0 to 16 years. The mean serum FRA concentration in non-diabetic children was 2.28±0.17 mmol/l and there was no signficant difference in the level between boys and girls. Statistically ignificant correlations were observed between age and the serum FRA level (r=0.47, p<0.01), as well as between age and the serum total protein level (r=0.45, p<0.01). There was also significant correiation between the serum level of FRA and total protein (r=0.47, p<0.01). This study revealed an increase in the serum FRA levels with aging in non-diabetic children, which might be due to an age-related elevation of the serum protein levels. The serum FRA levels in children must be evaluated with due consideration to these factors.
ExacTech® in a pen-sized digital glucose meter which requires 30 sec to reach a value after the appilication of whole blood, without wiping or washing of the test strip. The purpose of this study is to evaluate the accuracy of ExacTech®. When plasma samples of three different glucose levels (75 mg/dl, 165 mg/dl, and 351 mg/dl) were measured twelve times repeatedly with ExacTech®, the coefficients of variation were 8.0%, 7.8%, and 6.7%, respectively. When the venous blood glucose and plasma glucose levels from patients with diabetes were measured both with ExacTech® and with an autoanalyzer, the coefficient of correlation was 0.943 (n=156). We cnclude that this meter is both convenient and accurate, and is of potential use for self-monitoring of hood glucose levels.
