What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: FDA Class II diagnostic device with documented erroneous results not always caught by quality control, posing significant risk to patient care decisions. No injuries or hospitalizations reported, classifying this as a risk-of-harm product where injury has not yet been reported.

Plain-English summary

Siemens Healthcare Diagnostics has recalled Dimension Magnesium (MG) Flex reagent cartridges used in clinical laboratories to measure magnesium levels in patient blood samples. Approximately 26,851 units are affected, distributed nationwide and internationally.

The cartridges may exhibit imprecision that produces erroneous test results. In some cases, the laboratory's quality control system may not detect these errors, allowing incorrect results to be reported without an Abnormal Reaction warning flag. Based on customer data, affected cartridges may report magnesium levels 15% to 59% lower than actual values.

Affected lot numbers are FA2350, FA2356, GA2363, and FA3019. Healthcare facilities should identify and remove these cartridges from use. Patients who received magnesium test results from these lots should consult with their healthcare provider about the need for retesting.
