Errors in measurement of total bilirubin: a perennial problem.

Measurement of total bilirubin by use of bilirubin oxidase.

We used an enzymatic method for measuring total bilirubin in serum. Results by this method varied linearly with bilirubin concentrations to at least 300 mg/L. The day-to-day precision (CV) of the method ranged from less than 1% to about 11% at bilirubin concentrations of 183 and 12 mg/L, respectively. Commonly used anticoagulants, serum preparation materials, and selected drugs had no effect on...

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...

Comparison of Transcutaneous Bilirubin Measurement With Total Serum Bilirubin Levels in Preterm Neonates Receiving Phototherapy.

OBJECTIVE To compare transcutaneous bilirubin with total serum bilirubin in preterm neonates after initiation of phototherapy. METHODS Jaundice was assessed in 30 preterm neonates with transcutaneous bilirubin and total serum bilirubin before initiation of phototherapy and at 12 hr after initiation of phototherapy. A photo-occlusive patch was applied over the sternum. RESULTS Transcutaneous...
