What happened, in plain English

Siemens Healthcare is recalling all ADVIA Centaur Folate (500 Test Kit Reference) products for possible elevated folate results. This could lead to inaccurate health assessments if used without proper testing procedures.

Who’s affected

How to tell if you have this one
