Roche Elecsys Anti-TSHR immunoassay recalled for inconsistent test results
What this means
Roche Diagnostics has recalled certain lots of the Elecsys Anti-TSHR blood test due to inconsistent results across different laboratory instruments and variations between calibrator batches. These issues could lead to incorrect or delayed thyroid diagnosis and treatment.
- If your doctor ordered an Anti-TSHR (thyroid receptor antibody) test, contact your lab or healthcare provider to confirm which test kit was used
- Ask if your results came from one of the recalled lot numbers (840183, 874011, or 840177)
- If your lab used a recalled lot, discuss whether your test results should be repeated with a different kit
