Specific performance characteristics
The results given below are from a HemoCue Plasma/Low Hb
Photometer standardized against the HiCN-(ICSH)
Within-run precision
Within-run precision was determined on 5 photometers and by using
within house prepared aqueous and plasma solutions.

Between-run precision
Between-run precision was determined by using within house prepared
method. solutions. The sample were analyzed on 20 consecutive working days,
2
twice a day, in duplicate.
