TRUE METRIX Blood Glucose Meter Owner's Booklets
Trividia Health recalls TRUE METRIX meter booklets over inadequate E-5 error code instructions that may delay treatment.
Check your TRUE METRIX or TRUE METRIX PRO meter's owner's booklet. If the booklet does not clearly state that an E-5 error code may indicate a very high blood glucose level and instructs you to contact a healthcare professional immediately, stop using the booklet and contact Trividia Health for a corrected replacement.
Why it was recalled
Trividia Health is recalling owner's booklets and instructions for use for TRUE METRIX and TRUE METRIX PRO blood glucose meters because the labeling does not adequately describe the E-5 error code, which may indicate a very high blood glucose level requiring immediate medical attention. This could lead to delayed treatment.
