Urinary pregnancy testing with Sensitex, a tube macroflocculation system, produced a positive test by 17 days after basal-body-temperature-timed ovulation in 59% of determinations. Data from days 18 to 21 showed that a negative test was associated with a statistically significantly increased propensity for first-trimester abortion. Freezing of the urinary specimens, but not refrigerated sm, produced a positive test by 17 days after basal-body-temperature-timed ovulation in 59% of determinations. Data from days 18 to 21 showed that a negative test was associated with a statistically significantly increased propensity for first-trimester abortion. Freezing of the urinary specimens, but not refrigerated storage for five days, adversely affected the accuracy of the test.
使用Sensitex（一种试管宏观絮凝系统）进行尿液妊娠试验，在根据基础体温计时排卵后的17天，59%的检测结果呈阳性。第18至21天的数据显示，检测结果为阴性与孕早期流产倾向在统计学上显著增加有关。冷冻尿液标本而非冷藏保存五天，会对检测准确性产生不利影响，不过在根据基础体温计时排卵后的17天，冷冻尿液标本仍有59%的检测结果呈阳性。
