For children with suspected tuberculosis (TB), diagnosis is difficult and can often be painful and complicated. In a vulnerable population where many kids are being missed new diagnostics are critical. And preliminary results from a South African trial have given experts in the field, and patients, a glimmer of hope. While previous studies have looked at using saliva, urine and stool to test for TB with limited success, for the first time new research is investigating looking at oral epithelium, the cells on the surface of the mouth, and the results are promising.
