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) |

Effective Tuesday, February 20, 2024, the policy for home collected specimen drop offs for Outpatient Laboratories (“draw sites”) has been updated.
For all Corewell Health West Michigan locations: after registration, patients or their designated person will verify the specimen at the laboratory. Laboratory team members will verify the specimen is properly labeled and ensure they have everything needed to be able to test the specimen before the patient or their designated person leaves the building. This does not include specimens collected by a home health nurse or provider.
This will standardize our patient flow when arriving with a home collected specimen and will reduce the need for recollection due to missing information or improper collection.
When specimen collection orders are placed, please notify patients of the change to this process.
