Diagnostic test reagent may produce inaccurately low patient results
Siemens Healthcare's ADVIA Chemistry Microalbumin diagnostic test may produce falsely low results. Eight lots do not meet High-Dose Hook Effect and Prozone Effect specifications, potentially affecting microalbumin detection accuracy.
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 medical device with risk of inaccurate patient test results and potential for missed diagnoses, but no reported illnesses or injuries to date. Meets rubric criterion for risk-of-harm products where injury has not yet been reported.
Plain-English summary
Siemens Healthcare Diagnostics is recalling eight lots of ADVIA Chemistry Microalbumin_2 diagnostic test reagent used to measure microalbumin in human urine samples. The affected lot numbers are 612528, 616644, 620971, 623768, 636498, 640513, 658356, and 668872, representing 19,645 units distributed worldwide, including throughout the United States.
The recalled test does not meet High-Dose Hook Effect and Prozone Effect specifications as described in the product's Instructions for Use. This means that when microalbumin levels are very high, the test may produce inaccurately depressed (low) results instead of accurate measurements.
Laboratory professionals using the identified lot numbers on Atellica CH, Atellica CI, ADVIA 1800, ADVIA 2400, or ADVIA Chemistry XPT analyzer systems should discontinue use of affected test reagent and contact Siemens Healthcare Diagnostics for replacement guidance.
