Time- and temperature-dependent Pentraxin 3 stability in serum and bronchoalveolar lavage fluid samples

mycolabadmin

This study investigated how stable Pentraxin 3 (Ptx3), a protein used to detect fungal infections, remains when stored at different temperatures. Researchers found that Ptx3 stays reliable for up to 8 months in freezer storage at −20°C and even longer at −80°C, making it a dependable biomarker for diagnosing serious fungal infections. However, storing samples at room temperature (37°C) causes the protein to break down quickly, so proper cold storage is essential for accurate test results.

Comparison of galactomannan lateral flow assay and enzyme immunoassay to identify Aspergillus spp. in bronchoalveolar lavage fluid

mycolabadmin

Researchers compared two rapid tests for detecting a fungal infection called aspergillosis in lung fluid samples. One test uses a simple lateral flow format (like a COVID test), while the other is a more traditional enzyme immunoassay. Both tests had good agreement, with the lateral flow assay showing high accuracy and the advantage of being faster and requiring fewer laboratory resources, making it especially useful for hospitals with limited equipment.
