Phadia U.S. has recalled its ImmunoCAP Allergen c5, Ampicilloyl due to stability concerns. The *in vitro* quantitative assay is intended for use in measuring allergen-specific IgE in human serum or plasma. An FDA [recall notice](https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfRes/res.cfm?ID=162338&ref=fdaweb.com) says the stability concern is related to the device’s design. Users are being asked to stop using all current product, and scrap any unused inventory.
