Abdominal palpation of the uterus was carried out on 25 pregnant and 29 non-pregnant marmosets (Callithrix jacchus jacchus). 195 complete 24-hour urine specimens, collected between the first week of gestation and term (21 weeks), were tested with the Sub-Human Primate Tube (SHPT) test. No significant differences between the two methods in their ability to diagnose pregnancy were obtained between the first and 13th week of gestation. The SHPT test was seldom positive after the 13th week of pregnancy, whereas, with one exception, palpation always indicated pregnancy.
对25只怀孕的和29只未怀孕的普通狨猴（Callithrix jacchus jacchus）进行了子宫腹部触诊。在妊娠第一周和足月（21周）之间收集了195份完整的24小时尿液样本，并用亚人类灵长类动物试管（SHPT）试验进行检测。在妊娠第一周和第十三周之间，两种方法在诊断妊娠能力方面没有显著差异。妊娠第十三周后，SHPT试验很少呈阳性，而除一例例外，触诊始终表明怀孕。
