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

mycolabadmin

Pentraxin 3 is a protein marker that helps doctors detect serious fungal infections. This study tested how well this marker stays stable in blood and lung fluid samples when stored at different temperatures over long periods. The results show that samples should be kept frozen at −20°C or −80°C to preserve the marker, but samples left at room temperature or warmer are quickly damaged and unreliable for testing.

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.

Evaluating the Potential of Galactosaminogalactan as a Diagnostic Target for Invasive Aspergillosis

mycolabadmin

Researchers developed a new test to detect invasive fungal infections caused by Aspergillus by targeting a molecule called galactosaminogalactan (GAG) on the fungus surface. The test worked very well in mice with the infection and showed better specificity than current methods. However, the test did not detect GAG in blood or other body fluids from human patients, suggesting that additional research is needed before it can be used clinically.
