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.

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

Researchers tested how stable Pentraxin 3, a protein marker for fungal infections, remains when stored under different conditions. They found that samples stored in freezers at −20°C or −80°C kept stable for months, making Pentraxin 3 a reliable marker for diagnosing serious fungal infections. However, samples stored at warm temperatures degraded quickly, so proper cold storage is essential for accurate test results.
