Direct bilirubin higher than total bilirubin?
Both total and direct bilirubin measure the formation of azobilirubin, which is detected at 570/660 nm. The total bilirubin reaction contains surfactant and caffeine, which solubilize “indirect” bilirubin and accelerate the reaction (1). Direct bilirubin is a component of total bilirubin and therefore should always be smaller in value. The presence of a monoclonal immunoglobulin (2220mg/dL) fal...
متن کاملA 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 کاملMeasurement 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...

متن کامل"Direct" and total bilirubin tests: contemporary problems.
In eight unique challenges mailed by The College of American Pathologists Comprehensive Chemistry Survey to participating laboratories within 3 years, results for direct-reacting bilirubin (DBIL) were highly variable among the 12 largest peer groups, and most of the results differed greatly from the values obtained by a referred method. Peer-group mean values for total bilirubin (TBIL) were in ...
