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.

New Test: HPV High Risk Screen with HPV Genotype Reflex
Effective August 26, 2024, Corewell Health Laboratories West will be updating their High-Risk HPV testing. The new assay will be performed on the Abbott Alinity m at Corewell Health Reference Laboratory West, Grand Rapids. Testing will now automatically include HPV Genotype results whenever HPV is detected. There will no longer be a separate charge to the patient for HPV Genotype testing.
There will also be an expanded number of High-Risk HPV Genotypes reported:
- HPV Genotype 16
- HPV Genotype 18
- HPV Genotype 45
- HPV Genotype 31/33/52/58
- HPV Genotype 35/39/51/56/59/66/68
The new assay is FDA approved for Primary screening in addition to co-testing.

This winter, West Michigan influenza infections peaked in February 2024 and significantly declined throughout March and April 2024. Now with a low prevalence of circulating influenza, using the most sensitive diagnostic test is recommended in order to obtain accurate and actionable results. Influenza antigen testing (e.g. Sofia instrument) is no longer appropriate at this time and Influenza PCR testing should be ordered when clinically indicated.
| Low Influenza Prevalence |
High Influenza Prevalence |
|
| Recommended Order | Influenza PCR (LAB3255) | Influenza antigen testing (e.g. Sofia instrument) or Influenza PCR (LAB3255) |
