ABSTRACT
Although bilirubin meters are still continuously widely used to screen neonatal jaundice worldwide, they still need a metrological calibration method to evaluate the measurement accuracy of these kinds of devices. In this article, the author describes a new calibration method for evaluation of the bilirubinometers measurements and evaluates the results with one of the most common statistical metrological techniques to establish and evaluate the calibration method; the techniques are x̄ and R control charts. The method mainly depends on establishing a correlation between two units, the bilirubin unit (mg/dl) and one of the metrological standard SI units, the irradiance (W/cm2), experimentally to achieve the calibration method. The study results showed that the estimated correlation coefficient of irradiance response to the bilirubinometer under test was around 0.80, which is a primary indication that the method is a considerably valid technique. In addition, the calibration method was evaluated by the statistical parameters x̄ and R control charts, and the results concluded that the variability calibration process is stable, controlled, and hence could be promisingly utilized to evaluate various bilirubinometers with satisfied accuracy and precision in measurements.
