Bilitest 2000

OVERVIEW

BILITEST - device for objective evaluation of hyperbilirubinemia level in newborns using non-invasive transcutaneous method.

Commonly in newborns bilirubin determination is performed on a forehead near nose or on the upper part of the breast. Only a slight touch of a mobile measuring head to a baby's derma is needed for measuring. The result is given in international units for transcutaneous bilirubin index (TBI). This index has a high correlation degree with plasma bilirubin concentration (0,92).

TECHNICAL SPECIFICATION

  • Method of measurement – reflectance bichromatic photometry.
  • Light source – two white light-emitting diodes (LED).
  • Detector - two photocell system.
  • Measuring range - 0-50 (in unit of TBI) approximately corresponds to 0-500 μmol/l .
  • Optical unaccuracy - <10%.Imprecision (CV%) - <2%. Notes:
  • a) Metrological characteristics have been verified by Russian Federation State Commitee for Standartization and Metrology Body on the basis of five Reference Reading Checkers.
  • b) Control Reading Checker's data should be within the limits specified directly on the spots of Checker's installation within the covering.
  • Correlation between TBI and laboratory values for serum bilirubin levels - more or equal to 0.92.
  • Readout - three digits liquid crystal display (LCD).
  • Measuring cycle time - ~2 seconds. Between the measuring cycles the device is in a stand-by mode.
  • Power source – 3 batteries of AAA (or LR03) type.
  • The number of measuring cycles without replacing the batteries (during battery life) - >100,000
  • Weight (with batteries) - 150 grams.
  • Dimensions Width x Height x Depth - 65x135x35 mm.
