Uses and Limitations of Transcutaneous Bilirubin Measurement
Mayo Study of TcB, cont.
June 2009
This two by two concordance table shows how well transcutaneous bilirubin was able to predict high-risk serum bilirubin values when both were plotted in the Bhutani nomogram according to postnatal age at the time of measurement. The second row shows all infants with high-risk serum bilirubin values by the diazo method. The transcutaneous measurement predicted high-risk serum values in 51 of 52 infants with a high risk serum bilirubin, for a sensitivity of 98%. The first row of the table shows all infants with low-risk serum bilirubin values by the diazo method. The transcutaneous method correctly predicted low risk in only 48 of 125 infants with low-risk serum values, for a specificity of only 38%.
