Statistical parameter | Value | Criteria |
---|---|---|
Z′ | 0.73 | >0.5 |
%CV | 7 | <20 |
S/B | 9.6 | >3 |
S/N | 12.86 | >10 |
a: Z’ = 1–3(STD positive groups +STD negative groups)/(MEAN positive groups + MEAN negative groups).
b: %CV (coefficient of variation) = STD positive groups/MEAN positive groups × 100%.
c: S/B (signal-to-background ratio) = MEAN positive groups/MEAN negative groups.
d:S/N(signal-to-noise ratio)=(MEAN positive groups-MEAN negative groups)/((STD positive groups)2+(STD negative groups)2)1/2.
