The estimation of serum bilirubin

The estimation of serum bilirubin.

Noninvasive estimation of serum bilirubin.

OBJECTIVE The aim of this study was to evaluate the accuracy and clinical usefulness of a new computer-driven, hand-held device (Chromatics Colormate III) to estimate serum bilirubin from skin-reflectance (skin color) of neonates. STUDY DESIGN A total of 2441 infants (both term and premature) at two hospitals had repeated measurements of transcutaneous bilirubin. Of these infants, 900 had one...

Estimation of bilirubin in serum.

Most methods of estimating the concentration of bilirubin in serum are based on the van den Bergh reaction in which bilirubin couples with diazotized sulphanilic acid to give red " azobilirubin," the reaction being facilitated by the addition of an activator or catalyst such as ethanol. The many modifications of this reaction can be classified into two groups: (a) those in which ethanol is used...

A micromethod for the estimation of serum bilirubin.

The failure, up to the present, to obtain good films, which was the primary object of the investigation, appears to rule out the method for this purpose unless the third method mentioned above can be made to bear fruit. However, the rapidity of preparation, together with the suggestion of better results on culture, merits further consideration. The method commends itself for the examination of ...

Estimation of bilirubin binding capacity of neonatal serum.

One aim of laboratory investigation in neonatal jaundice is to prevent kernicterus from occurring. Estimation of the bilirubin-binding capacity of serum is an important measurement along with total bilirubin determination. With a convenient Sephadex competitive binding procedure, KERNLUTE provides information on whether or not the neonate's bilirubin-binding capacity has been exceeded. Further ...
