在对英华公司船员体检过程中,我们发现船员的尿液潜血试验显阳性者较多。为此,我们对2009年10~11月在本院体检的500名船员尿潜血试验进行了检测,同时对500名陆岸体检人员的该项目进行检测,并将两组人群的总阳性率进行了比较,结果发现船员的阳性率远高于陆岸体检人员的阳性率,现 During the medical examination of IAC Company’s crew members, we found that the crew’s urine occult blood test was significantly more positive. To this end, we tested the urinary occult blood tests of 500 crew members who took physical exams in our hospital from October to November in 2009, examined the project of 500 land-based medical personnel and carried out the total positive rates of the two groups The results showed that the positive rate of the crew was much higher than the positive rate of medical staff on the shore
