Sysmex SF-3000 Operator's Manual -- Revised September 1995 1-23
Table 1-4: System Specifications (Continued)
Differential Accuracy The instrument differential is compared by using 100 or more fresh samples
to the reference 400 cell manual differential (200 counts with 2 Lab. Techs.),
as per NCCLS H-20A. MONO% is compared by using the monoclonal
antibodies. Results are displayed as a range of values that are the mean
differences between the methods, expressed to a 95% confidence interval.
NEUT% Coefficient correlation r ≥ 0.90
LYMPH% Coefficient correlation r ≥ 0.90
MONO% Coefficient correlation r ≥ 0.75
EO% Coefficient correlation r ≥ 0.80
BASO% Coefficient correlation r ≥ 0.50
Additionally, the mean difference from that obtained on the standard
instrument should be the following:
NEUT% within ± 3.0 NEUT%
LYMPH% within ± 3.0 LYMPH%
MONO% within ± 2.0 MONO%
EO% within ± 1.0 EO%
BASO% within ± 1.0 BASO%
