Researchers developed and tested a new rapid test (TG11-LFD) for detecting mucormycosis, a dangerous fungal infection, using a simple device similar to a COVID rapid test. The test detects a specific protein marker released by Mucorales fungi in lung fluid samples. In testing with 62 clinical samples, the new test correctly identified about 77% of actual infections and was negative in about 76% of non-infected samples. This affordable, simple test could help doctors quickly diagnose mucormycosis and start life-saving treatment faster, especially in countries with limited laboratory resources.
