This study reviews how well a molecular test called PCR can diagnose mucormycosis, a dangerous fungal infection. Researchers analyzed 30 studies covering over 5,000 patient samples and found that PCR works very well for detecting this infection, especially when using samples from the lungs. Blood tests were also effective but slightly less sensitive. The study recommends using PCR as part of updated diagnostic guidelines to help doctors catch this serious infection earlier, potentially improving patient outcomes.
