Effect of ambient temperature on analytical and clinical performance of a blood glucose monitoring system: Omnitest Sensor glucose meter.

abstract：BACKGROUND:Biological variation of an analyte is an important determinant of its usefulness. Intraindividual variation in serum thyroid hormones, parathyroid hormone (PTH) and insulin-like growth factor-1 (IGF-1) in healthy subjects was determined in this study. METHODS:Blood samples were taken at weekly intervals for...
