目的探讨B超诊断华支睾吸虫感染的临床应用价值。方法采用改良醛醚法检查粪便虫卵、ELISA法测定血清抗体,对经B超检查疑为华支睾吸虫感染的就诊者进行调查测定。结果实验室检测B超怀疑者269例,检获虫卵和(或)检出抗体146例,阳性率为54.3%。男性检测阳性率60.2%(130/216),女性30.2%(16/53)。有食鱼生史者(58.5%)捡出率高于无食鱼生史者(33.3%),但无统计学意义。对164例进行虫卵及抗体两项检测,虫卵及抗体均未检获(双阴性)者61例(37.2%)。认为,当前B超检查华支睾吸虫感染仍存在较高假阳性率。结论B超诊断华支睾吸虫病假阳性率很高,作为一项诊断技术有待完善和改进。
Objective To investigate the clinical value of B-ultrasound in the diagnosis of Clonorchis sinensis infection. Methods The testosterone was detected by the improved aldehyde ether method and the serum antibody was detected by ELISA. The patients diagnosed as suspected Clonorchis sinensis infection by B ultrasound were investigated. Results There were 269 cases of suspected B-ultrasonography in the laboratory. 146 cases of eggs and / or antibodies were detected, the positive rate was 54.3%. Male test positive rate of 60.2% (130/216), women 30.2% (16/53). Those who had a history of eating fish (58.5%) had a higher detection rate than those who did not eat fish (33.3%), but they were not statistically significant. Sixty-four cases of eggs and antibodies were detected in both eggs and antibodies were not seized (double negative) in 61 cases (37.2%). That the current B-check Clonorchis sinensis infection is still higher false positive rate. Conclusion The false positive rate of Clonorchiasis sinensis diagnosed by B-ultrasound is high, which needs to be improved and improved as a diagnostic technique.
