UNISTAT® Bilirubinometer : Chemistry-free, no dilution solution for point-of-care Total Serum Bilirubin measurement

Reicherts UNISTAT® Bilirubinometer uses a photometric analyzer to provide accurate and rapid measurements of total serum bilirubin (TSB) concentration in undiluted serum. The photometric analyzer is the ideal STAT-level analyzer for determining TSB in newborns.

Principles of Operation:

The Reichert UNISTAT® is a direct spectrophotometer that measures total bilirubin in neonatal serum samples. Dilution is not necessary. A beam of light is passed through the sample cuvette. The beam is split by a dichroic mirror and directed toward the 460nm and 550nm filters. The transmittance of the light exiting the filters is measured by photodetectors.

The control electronics calculate total bilirubin based on output from the photodetectors. Since peak absorbance is shared by bilirubin and oxyhemoglobin at 460nm, it is necessary to measure oxyhemoglobin at 550nm. The difference in the readings at 460nm and 550nm is the total bilirubin value, corrected for the presence of oxyhemoglobin. Since the UNISTAT® measures and subtracts oxyhemoglobin, bilirubin results are not affected by hemolyzed samples.
