摘　　要：目的:以昆明市某二级甲等医院患者粪便隐血试验结果为依据,分析出现粪便隐血的常见病因。方法:回顾性分析昆明市某二级甲等医院2021年1—2月2000份使用单克隆抗体法进行粪便隐血检测的试验结果。结果:2000例患者粪便隐血试验中,阳性率为24.30%,年龄<50岁的患者粪便隐血试验阳性率最高,为43.51%;年龄≥50岁的患者粪便隐血试验的阳性率随着年龄增长而升高(除80~89岁患者阳性率略有下降外)。结论:消化道出血性疾病、消化道恶性肿瘤、使用某些药物都可导致粪便隐血试验结果呈阳性,临床医生分析患者粪便隐血试验阳性结果时需要鉴别其病因,对于高度怀疑消化道出血者,当使用单克隆抗体法检验粪便隐血试验结果呈阴性时,需要进一步稀释粪便标本后重新检测,以避免出现假阴性结果而延误疾病诊治。Objective:To analyze the common causes of fecal occult blood based on the results of fecal occult blood test in a second class A hospital in Kunming City.Methods:The results of fecal occult blood test using monoclonal antibody method were retrospectively analyzed in 2000 samples from a second class A hospital in Kunming City from January to February 2021.Results:Among the 2000 samples,the positive rate of fecal occult blood test was 24.30%,and the positive rate of fecal occult blood test in patients under 50 years old was the highest(43.51%).The positive rate of fecal occult blood test in patients older than 50 years increased with age(the positive rate of patients aged 80 to 89 decreased slightly).Conclusion:Digestive hemorrhagic disease,gastrointestinal malignancy and the use of some drugs can lead to positive results in fecal occult blood test.The clinician needs to identify the cause when analyzing positive results of fecal occult blood in patients.For those who are highly suspected of digestive tract bleeding,if the results of fecal occult blood test by monoclonal antibody method are negative,the fecal sample should be further diluted and retested to avoid false negative results and delay disease diagnosis and treatment.
