### Major Recall Alert: DxC 500 AU Clinical Chemistry Analyzer Recalled Due to Risk of Incorrect Test Results
Beckman Coulter has issued an important recall for their **DxC 500 AU Clinical Chemistry Analyzer** due to a flaw that may cause test results to be assigned to the wrong sample ID under specific workflow conditions. This recall, which began on **March 7, 2025**, could significantly impact laboratories and patients if left unaddressed. If you use or rely on this equipment, here’s everything you need to know to protect patient safety.

## Why This Recall is Important
The **DxC 500 AU Clinical Chemistry Analyzer** is a critical device used to analyze clinical chemistry samples in laboratory settings. The recall stems from an issue where the analyzer may assign test results for one sample (Sample A) to another sample (Sample B) under specific scenarios. This error can occur if:
- A barcoded sample tube (Sample A) is loaded, but tests remain in “pending” status for that sample.
- The operator places a second sample tube (Sample B) in the same position without successfully scanning the barcode or without a label.
- The analyzer assumes Sample A is reloaded and generates test results using Sample B, causing a misidentification.
### Potential Consequences of the Issue
- **Incorrect Test Results:** The second sample (Sample B) falsely receives pending results of the first sample (Sample A).
- **Missed Reporting:** Results for the first sample (Sample A) are not completed or reported.
- **Patient Safety Risks:** This could lead to improper diagnoses, delayed treatments, or unnecessary medical interventions, impacting overall patient care.
