Stago recalls STA-Liquid Anti-Xa 4 kits (model 00311US) due to potential contamination with fibrinogen reagents in heparin tests. Affected users should contact Stago for details.
Potential for contamination of STA-LIQUID ANTI-Xa by Stago Fibrinogen reagents in UFH and LMWH applications.
Stago recalls its STA-Liquid Anti-Xa 4 kits (model 00311US) because they might mix with fibrinogen reagents used in heparin tests. This could lead to inaccurate test results if the kits are used with certain analyzers.
The kits could mix with fibrinogen reagents used in unfractionated heparin (UFH) and low molecular weight heparin (LMWH) tests. This contamination might cause inaccurate test results, but it does not cause direct harm to users.

Check for the model number 00311US on the kit packaging. The kits are intended for use with Stago STA-R, STA Compact, or STA Satellite analyzers for heparin level testing.
