Jaundice Meter (JM-103) User Manual (usr070)

Graph 23 – Hospital Study Site A Birthweight Error Plot, Sternum

Reproducibility

Reproducibility of the light output of the device was tested daily using 
the checker. The checker determines the intensity of the light output of 
the device. The accuracy of the device is determined by how well the 
detectors in the unit measure the returning light. The results of the 
device testing using the checker show that the device produced output 
within the required range over the course of both hospital studies.

Reproducibility testing in the patient population can be derived from the 
data taken in Hospital study site A. The reproducibility data is based on 
467 babies. Three independent measurements were taken at each site, 
forehead and sternum. Each measurement was recorded, the mean and 
standard deviation computed and recorded. The average standard 
deviation for forehead and sternum measurements was 0.3 for both.
