The reactions for the diagnosis of pregnancy by the use of urine from patients who are receiving tranquilizing drugs of the phenothiazine group have given false positive results when performed in the North American frog Rana pipiens. Such false positive reactions are not obtained when the South American toad Bufo arenarum is used.
利用接受吩噻嗪类镇静药物患者的尿液进行妊娠诊断的反应，在北美牛蛙（Rana pipiens）身上进行时会得出假阳性结果。而使用南美蟾蜍（Bufo arenarum）时则不会出现这种假阳性反应。
