Abstract:
AO bilirubinometer is a direct reading spectrophotometer specifically designed to measure total bilirubin using sera from newborn infantsl A study was performed to compare the bilirubin values obtained using the AO bilirubibometer and modified Diazo method(Rappaport method). The results were as follows : 1. The average percentage of recovery of AO bilirubinometer was 98.7%, while modified Diazo method was represented as 95.3%. 2. In comparison of two bilirubin techniques, the regression is linear, expressed by Y=1.16X-2.42, where values obtained as the bilirubinometer was on X axis and those from the modified Diazo mt\ethod on Y axis. The correlation coefficient was 0.95. 3. The variability of bilirubin values by cuvette was negligible, average percentage of variation coefficient being 0.1%. 4. The variability of bilirubin values by examiner was also negligible, the evarage percentage of bilirubin variation coefficient being 0.67%.
