General Information

Positive COVID-19 PCR Communications

At the beginning of the COVID-19 pandemic Spectrum Health Laboratory implemented a protocol to call providers and patients to notify of positive COVID-19 PCR testing.  The pandemic has shifted to an endemic phase and a positive COVID-19 test is no longer considered a critical value. Effective Friday, August 26, 2022, Spectrum Health Laboratory will no longer call positive COVID-19 PCR testing, for inpatient or outpatient specimens.

Results for COVID-19 PCR will still file to the patient’s chart in Epic and reported to the ordering provider through usual means of receiving results (fax or electronic) and to the Michigan Department of Health and Human Services (MDHHS). Patient’s will still be notified via their MyChart as well.
