A method for diagnosing pregnancy in the guinea pig by manual palpation was developed. Using this technique, pregnancy was detected between the 15th and 30th day of gestation with 98% accuracy. The 2% error consisted of animals that were pregnant but diagnosed as nonpregnant. Common mistakes that led to diagnosing nonpregnant animals as pregnant were: (1) palpation of fecal pellets; (2) palpation of left kidney; and (3) palpation of the sartorius muscle. Common errors that led to diagnosing pregnant animals as nonpregnant were: (1) failure to search the entire abdomen; (2) too close apposition of thumb and forefingers while searching the abdomen; and (3) failure to deprive animals of feed before palpation.
开发了一种通过手动触诊诊断豚鼠妊娠的方法。使用该技术，在妊娠第15天至第30天期间检测妊娠的准确率为98%。2%的误差包括怀孕但被诊断为未怀孕的动物。导致将未怀孕动物诊断为怀孕的常见错误有：(1)触诊粪便颗粒；(2)触诊左肾；(3)触诊缝匠肌。导致将怀孕动物诊断为未怀孕的常见错误有：(1)未对整个腹部进行检查；(2)在检查腹部时拇指和食指靠得太近；(3)触诊前未给动物禁食。
