3.2.2.4. Calculation of the LD50

The results are analysed in order to calculate the LD50 at 24 and 48 h and, in case the study is prolonged, at 72 h and 96 h. The mortality data should be analysed using appropriate statistical methods (LD50 calculated based on data corrected for control mortality, see 8.2.1.2. and 8.4.1.)
