Rats 68% better at spotting TB than FDA-approved test: Study
A Tanzania-based study found that rats can sniff out tuberculosis 68% better than the standard swab test, approved by the US health agency FDA. The researchers trained the rats with odour of tuberculosis-infected mucous, who then identified 57 additional cases of TB among 982 children. On confirming the results by a WHO researcher, the additional patients were treated as well.
