Reminder: COVID Orders and Scheduling

Effective July 1, 2021, Spectrum Health no longer offers patient self-screening through MyChart or telephonic COVID screening appointments to patients. Patients will need an order from their provider prior to scheduling a COVID-19 test. Patients should be symptomatic or have a recent exposure, all other visit types should go through Michigan.gov (travel, athletic, or return to work or school, etc.)

If the patient does not have a provider, they may utilize the SHNow On Demand Visit via MyChart or find testing site options on Michigan.gov.

Once the order is placed, patients may schedule an appointment through MyChart or calling the Covid Hotline (for paper orders).

Resolved: Change in testing for Lyme Total Antibody

As of February 11, 2021, this has been resolved. Testing has resumed at Spectrum Health Regional Laboratory Immunochemistry Department.

Starting November 1, 2020, the Lyme Total Antibody test will temporarily not be performed in-house and will be sent out to the Mayo Clinic Laboratories using the Lyme Disease Serology, Serum.  This is due to the backorder of reagents from the vendor until approximately January 2021.

Lyme Disease Serology, Serum is available to order in Epic. Lyme Total Antibody will still be available to order, however, when the specimen arrives to the laboratory the order will be switched to the Lyme Disease Serology, Serum.

Similarly, to the current in-house test, the Mayo assay is also a Lyme total antibody assay, detecting both IgG and IgM antibodies, with the same specimen type as the in-house test.  However, test turn-around-times may be increased.

Lastly, this change will have no effect on the reflexing of positive samples to the confirmatory Lyme Disease Antibody, Immunoblot, Serum. Continue Reading

Serum Kappa/Lambda Free Light Chain Assay Update

Effective September 28th, 2020, a new generation of the serum kappa/lambda free light chain assay has been implemented.

With the implementation of the new generation of the assay there is an approximately 20% negative bias for kappa free light chains in serum containing >20 mg/dL kappa free light chain.  This may affect the trending for patient who are serially monitored by this assay. Continue Reading
