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.

On Monday, November 20, 2023, Corewell Health Laboratories West will adjust several hematology result components units of measure.

Effective Monday, October 2, 2023, the Outpatient Lab Draw Sites in Kent, Ottawa, and Muskegon counties (excluding the Zeeland Hospital and Gerber Hospital sites) will begin a new process for walk-in patients.
Registration staff will begin informing the patient of their wait times based on the scheduling template available for that site for that day. This will allow the patient to make an informed decision on whether to wait, come back at a later time, or schedule an appointment time that works best for them. Patients choosing to schedule, may schedule for any available sites, times and dates in MyChart, or they may schedule with the registrar for the next 24-48 hours. (Note: lab staff does not have the ability to schedule patients.)
Additionally, at this time, Blodgett Outpatient Lab is temporarily closed until further notice. Sites closest to Blodgett are the Integrated Care Campus at 426 Michigan St NE, 4100 Lake Drive, and Integrated Care Campus at 2750 East Beltline, or patients may visit Find a Doctor | Corewell Health to find a lab location nearest to them.
