- Other effects / acceptance of results:
- Optical density (as a marker of cell viability) of test item is comparable to value of the negative control. The test is to be considered as valid because:
a) optical density of negative control (mean value: 2.074+/-2.9%) > 0.8 and < 3.0 and standarad deviation <= 18%. Historical mean= 1.423
b) relative cell viability of the positive control (mean value: 1.10; standard deviation 2.22%) < 3.42% and standard deviation <= 18%
c) standard deviation of test item < 18%
