Sample Radiometer recommends that ctHb in the adult samples
(with FHbF = 0) and fetal samples (with high FHbF) is set to
 15 g/dL (9.3 mmol/L), sO
2
 100 % and pH  7.4.
The "Enabled for all levels" HbF Correction function should
be enabled in order to have the FHbF value displayed for the
adult sample.
Averaging repeated measurements on blood from different
donors gives an optimized accuracy of the correction.
Averaging repeated measurements on blood from the same
donor also improves the accuracy.

The units for FO

Hb and FHHb are Fraction.
After the user-defined corrections of the parameters sO
2
, FCOHb and FMetHb
have been carried out, FO
2
Hb and FHHb are automatically calculated using the
formulae stated below, since the sum of the fractions FCOHb, FMetHb, FO

Hb
and FHHb as defined must be equal to 1.0:
