Thai health authorities will retain stool examinations as the standard test for liver fluke infection after follow-up tests confirmed only four infections among 292 university students who had initially tested positive using a new urine screening kit, raising questions about the test’s performance in a real-world setting.
The Department of Disease Control (DDC) said on Tuesday that the World Health Organization recommends stool examination as the definitive diagnostic method, so Thailand will continue to use it while experts develop guidelines on the appropriate use of the urine-based screening kit.
