Why it was recalled

BCR wands that received a configuration update (released under Service Information No. 2026-07 on or after April 8, 2026) may assign patient results to an incorrect patient ID. The root cause is a race condition introduced when the "price check" feature was disabled to reduce excess current draw. This causes buffered data from a previous scan to be transmitted instead of the most recent scan, populating a prior patient ID instead of the current one. This can result in erroneous results being attributed to the wrong patient, potentially leading to inappropriate clinical management.

FDA root cause category: Software Design Change

Product description

Brand Name: GEM Premier 5000 Product Name: GEM Premier 5000 Model/Catalog Number: 00024019255 Product Description: The GEM Premier 5000 system provides fast, accurate, quantitative measurements of heparinized whole blood pH, pCO2, pO2, Na+, K+, Cl-, Ca++, glucose, lactate, Hct, total bilirubin and CO-Oximetry (tHb, O2Hb, COHb, MetHb, HHb, sO2) from arterial, venous or capillary samples. Intelligent Quality Management 2 (iQM2) is used as the quality control and assessment system for the GEM Premier 5000 system. iQM2 is an active quality process control program designed to provide continuous monitoring of the analytical process before, during, and after sample measurement with real-time, automatic error detection, automatic correction of the system and automatic documentation of all corrective actions, replacing the use of traditional external quality controls (QC). Facilities should follow local, state and federal regulatory guidelines to ensure that a total quality management system is followed. The GEM Premier 5000 system makes use of potentiometric sensors to measure pCO2, pH, Na+, K+, Cl-, and Ca++. It uses amperometric sensors to measure pO2, glucose, and lactate concentrations. Blood conductivity is the method used to measure hematocrit. CO-Oximetry and total bilirubin measurements involve chemically lysing the whole blood sample and then utilizing a broad spectrum spectrophotometer to evaluate the sample at a variety of wavelengths.
