摘　　要：目的探讨二维混合血清法的混合样本数K、被检测样本的阳性率P与节约检测次数百分率L之间的关系。方法建立概率模型并用图形说明它们之间的关系。结果当阳性率P在0·0001到0·2000之间时,用二维混合血清法能减少99·36%到8·12%的检测次数。结论二维混合血清法能明显减少检测次数从而可显著降低检测费用。Objective To discuss the relationship among the number of the minipool samples K, the positive rate P of the samples screened, the percent of the saved test times L. Methods To establish the probability model and explained their relationship by graphs. Results when the positive rate P from 0. 0001 to 0. 2000, applying two dimensional minipool could decrease test times by 99.36% to 8.12%. Conclusion It showed that two - dimensional minipool could decrease test times and decrease expense obviously.
