An equipment issue resulted in artificially high parathyroid hormone results for some patients from July 31- August 17, 2024. We have repeated testing on the potentially affected samples, corrections were made as necessary, and providers for the impacted patients have been notified.
Review of quality indicator data suggested that issue affecting the results began July 31. Not all patient values were affected, but those that were had artificially high values. The laboratory repeated all PTH testing from this instrument for which remaining sample was available, corrected results, and contacted providers via epic inbox message for CHW providers and other appropriate means for CHW affiliates and external providers whose lab work is performed at CHW in Grand Rapids. Providers of potentially impacted patients whose samples could not be repeated have also been notified.
Recommendations
Providers should review messages and notifications for corrected results for their patients.
Contact the laboratory whenever suspicious results are received. We have many systems to help us identify analytical issues, but sporadic issues such as this one are hardest to detect. Provider inquiries are invaluable in identifying such issues.
