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

Hemoglobin A1c Testing Update

For Hemoglobin A1c testing, Mayo Clinic Laboratory has switched to an Ion-Exchange High-Performance Liquid Chromatography (HPLC) method (Bio-RAD D100) which is the same method of A1c testing used at Spectrum Health Regional Laboratory.  They no longer offer the alternative method, boronate affinity chromatography, for A1c testing.

When A1c cannot be determined due to  interferences that affect the Bio-RAD 100 method, measurement of serum fructosamine is recommended (Mayo test FRUCT). Continue Reading
