General information
The optical system of the ABL90 FLEX analyzer is designed to measure the
following parameters:
Parameter Description
ctHb Concentration of total hemoglobin
sO
2
Oxygen saturation
FO
2
Hb Fraction of oxyhemoglobin
FCOHb Fraction of carboxyhemoglobin
FHHb Fraction of deoxyhemoglobin
FMetHb Fraction of methemoglobin
FHbF Fraction of fetal hemoglobin
ctBil Concentration of total bilirubin (the sum of unconjugated
and conjugated bilirubin) in plasma
NOTICE: ctBil can be measured on a whole-blood or plasma sample. Plasma
samples provide the optimal measurement performance. To obtain optimal
accuracy when following a patient trend in
ctBil, use the same sample type and
the same analyzer.
The optical system is based on a 138-wavelength spectrophotometer with a
measuring range of 467-672 nm. The spectrophotometer is connected via an
optical fiber to a combined hemolyzer and measuring chamber.
