The monitoring of the icterus course in the new born is of great importance for a quick check for iper-bilirubine so to promptly act on the new born. The TOT BIL is an analyser for the bilirubin measurement on sample of whole blood drawn with a micro capillary after centrigugation. The sample is analyzed through a photometric reading system with a double beam and automatic zero setting and checkings. Reading time 1 sec. No reagents are required for the test. The standard and the calibration maintain themselves stable and unaltered in time, highly reducing the need for maintenance and technical assistance.
