On March 12th, 2025, the reporting for Protein Electrophoresis, 24 Hour Urine, do IFE if Indicated (LAB111444) and Protein Electrophoresis, Random Urine, do IFE if Indicated (LAB111445) will be updated to harmonize with Monoclonal Gammopathy Screen (LAB1230573) and Protein Electrophoresis, Serum, IFE if Indicated (LAB844).
The changes that will occur include the following.
- A single interpretive comment (Pathologist Interpretation Urine Protein Electrophoresis) that will encompass both the electrophoresis portion of the test and any immunotyping.
- Quantitation of monoclonal proteins will no longer be part of the interpretation but rather documented as discrete fields under Urine Protein Electrophoresis in result review. As a result, the interpretation will not include a comment about how the monoclonal protein has changed between studies.
- The quantitation of the monoclonal protein will only include mg/24-hour concentration and not the percentage.
TEST INFORMATION
- Protein Electrophoresis, 24 Hour Urine, do IFE if Indicated (LAB111444)
- Protein Electrophoresis, Random Urine, do IFE if Indicated (LAB111445)

Effective December 4, 2024, breath methane will be added to Bacterial Overgrowth, Breath Test (LAB3295) and Lactose Intolerance, Breath Test (LAB3097). As a result, the test will include both breath hydrogen and methane. Methane is being added as a small percentage of patients who have either bacterial overgrowth or lactose intolerance will not produce hydrogen when challenged during the test. These patients are considered methane-producers.
In addition, the collection time point of 150 minutes is being eliminated to align with system-wide standards.

As of January 26, 2024, for the following tests, the testing platform has changed from EliA Fluorescence Enzyme Immunoassay (FEIA) from Thermofisher to Multiplex Flow Immunoassay from Biorad. Please review the lab catalog for any changes to collection information or reference ranges.
• Anti-dsDNA Antibody
• Cyclic Citrullinated Peptide (CCP) Antibody
• Celiac Antibody Cascade
• Tissue Transglutaminase Antibody
• Gliadin Antibodies
Effective December 20, 2023, Rheumatoid Factor, IgM, Quantitative will be replaced with Rheumatoid Factor.

Webinar: Optimizing Care of the Respiratory Patient – The Role of Specific IgE Testing
It’s the season of sunshine and blooms which also means it can be a season of sneezing, itching, and a lot of trouble getting a good breath in for some.
⇒Are you prepared to meet the needs of your patients that may be suffering from some of these symptoms?
⇒Are you well versed in the difference between a sensitivity and a clinical allergy and how you can differentiate between the two?
⇒Do you know the resources we have at Corewell Health to assist in these determinations?
On January 24th, 2022 Rubella Antibody, IgG, Serum (LAB496) and Rubella IgG Antibody Quantitative (LAB3544) will be combined as LAB496 and moved to the Immunochemistry laboratory due to reagent constrains with the current vendor.
Testing will be available Monday-Friday with a turn-around-time of 1-3 days. Results will be reported qualitatively as Immune or Not Immune. If quantitative results are needed, please fax Immunochemistry at 616-267-2771 or call 616-267-2770.

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).
