TECHNICAL BASICS
• The calculation of indices is based on international principles in hematology.
• The method for counting blood cells is based on the electric resistance detection prin-
ciple.
• Hemoglobin concentration is determined by a photometric measuring method.
FUNCTIONAL DESCRIPTION
ANALYSI S
Anexactvolumeofsampleisaspiratedwiththeaspiratingpiercer(pipette).
Thisvolumeofthesampleisthentransferred(togetherwithadenedvolumeofdilu-
ent)tothemixingchamberandfromthereautomaticallytothetransducer.
All parameters are analyzed using the same transducer in the order:
(1)WBC/HGBand(2)R B C / P LT.
ForWBC/HGBanalysis,theWBC/HGBlyseisaddedtothemeasuringchambertopro-
vide further dilution and hemolysis of the sample‘s RBC.
This process takes about ten seconds.
During this reaction period, the erythrocytes are dissolved under the influence of the
lysis, hemoglobin is released and is converted into red methemoglobin. The leukocytes
remain intact.
Thevolumeandnumberoftheleukocytes(WBC)aredeterminedbytheDCdetection
method. In the HGB detector, the hemoglobin concentration is photometrically meas-
ured.
ForRBC /PLTanalysis,thedilutedsampleistransferredfromthemixingchambertothe
transducer, and the volume and blood cell count for erythrocytes and platelets are ana-
lyzed by the DC detection method.
