Methodology

Spectophotometric (diazonium salt) on Abbott Architect

Reported

STAT 1 hour, Routine 4 hours

Additional Information

Eltrombopag up to 200 mcg/mL had negligible effects on total bilirubin concentrations when measured using the Abbott or Roche diazo methods.  Ref: Adams DF and Sellers TS, Arch Pathol Lab Med, 2016, 140(5): 391-392

These pediatric critical cutoffs were recommended by Dr. Tom Newman in the Department of Pediatrics based in part on the nomogram of Bhutani et al for well newborns (gestational age of 36 weeks or more with birth weight of at least 2000 g, or a gestational age of 35 weeks or more with birth weight of at least 2500 g). Reference: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation, Pediatrics 114:297-316, 2004.
 
The cutoffs take into consideration uncertainty about the exact age of the infant as reported by the hospital computer; the dating of age by the hospital computer system is not entirely accurate and cannot provide patient age in hours. Detailed information on hourly bilirubin levels at specific time points after birth to 6 days of age which predict risk of developing severe hyperbilirubinemia are available at www.bilitool.org.
