A Comparison between Transcutaneous Bilirubin (TcB) and Total Serum Bilirubin (TSB) Measurements in Term Neonates
Background: Transcutaneous bilirubinometry (TCB) is a simple method for estimating bilirubin levels in neonates. This method is noninvasive, quick, and painless. We aimed to compare serum and cutaneous bilirubin measurements in term neonates.Method: In this descriptive cross-sectional study, 200 neonates with icter with birth weights of at least 2500 grams were studied. TCB was measured using a...
متن کاملInterlaboratory variability of bilirubin measurements.
During an 8-month study, 14 laboratories used automated analytical systems to measure total bilirubin concentrations in lyophilized bovine specimens containing 38, 169, and 253 micromol/L bilirubin (2.2, 9.9, and 14.8 mg/dL, respectively). The measured mean +/- SD (n, range) were: 39 +/- 7 micromol/L (n = 90, 31-53) [2.3 +/- 0.4 mg/dL (1.8-3.1)]; 176 +/- 29 micromol/L (n = 89, 146-222) [10.3 +/...
متن کاملBilirubin interference in kinetic creatinine determination.
194 CLINICAL CHEMISTRY, Vol. 25, No. 1, 1979 gas chromatography before and after acid (6 mol/L HC1) and alkaline (NaOH) hydrolysis. We frequently observe a peak in the lactic acid position after alkaline hydrolysis. After acid hydrolysis of the same urine no lactate isobserved, but a peak appears in the position of levulinic acid. The mass spectra of these two peaks were identical with those of...
متن کاملUtility of Decision Rules for Transcutaneous Bilirubin Measurements.
BACKGROUND Transcutaneous bilirubin (TcB) meters are widely used for screening newborns for jaundice, with a total serum bilirubin (TSB) measurement indicated when the TcB value is classified as "positive" by using a decision rule. The goal of our study was to assess the clinical utility of 3 recommended TcB screening decision rules. METHODS Paired TcB/TSB measurements were collected at 34 ne...
