We investigated the accuracy of the in-home pregnancy test in early pregnancy detection. A total of 109 women volunteered to perform their own pregnancy test using one of three brands. Kit accuracy ranged from 45.7 per cent to 89.1 per cent (95 per cent confidence interval), differing from the 97.4 per cent average of manufacturer claims. Sensitivity was calculated at 56 per cent, while specificity was 83 per cent. Predictive value of a negative result was 56 per cent and the predictive value of a positive test was 83 per cent.
我们研究了家用妊娠试验在早期妊娠检测中的准确性。共有109名女性自愿使用三个品牌之一进行自我妊娠检测。试剂盒的准确率在45.7%至89.1%之间(95%置信区间),与制造商宣称的97.4%的平均准确率不同。敏感性计算为56%,特异性为83%。阴性结果的预测值为56%,阳性检测的预测值为83%。
