This study compared two blood tests for diagnosing chronic pulmonary aspergillosis (CPA), a chronic fungal lung infection caused by Aspergillus. The rapid immunochromatographic test (ICT) performed better overall than the traditional ELISA laboratory test, making it more useful as a quick diagnostic tool, especially in areas without advanced laboratory facilities. However, both tests were less accurate in patients who had recently taken antifungal or steroid medications.
