Analytische und technische Zuverlässigkeit des ELT-8 Laser Hämatologie Zellzählers

Abstract

Analyticäl and technical reliäbility of the ELT-8 laser haematological counterSünimary: The ELT-8 laser haematological cell counter is a fully mechanized Instrument, which measures the forward scatter of light from a helium-neon laser caused by suspended particles.The apparatus has high practicability, and uses a very small sample volume of 100 . The operational proeedure is simple and quickly learned. In the second year of Operation, down time for the Instrument was, on average, 8 hours/month.Depending pn the parameter, the precision of the measurements are between 0.5 and 4% in series, and l -9% day-to-day. The highest scatter of results was shown for thrombocyte counting, but this may be due to instability of the control samples. There was no carry over between samples containing different concentrations of any of «the measured parameters. Lipaemia and haemolysis of samples can lead to false results
