After consultation with our clinical partners, Spectrum Health West Michigan Laboratory will be adjusting the pediatric reference ranges for our new ALT and AST reagents in an effort to better serve our population. Numerous academic studies were reviewed, and the values listed below were adopted on August 3, 2022:
Effective August 2, 2022, reference ranges for the below tests will be updated to better align with the vendor’s recommendation and with Spectrum Health Lakeland Laboratory. Please click on the links below and scroll to the Reference Range field to see the updated ranges.
• Lithium Level [LAB29]
• PTH Intact [LAB108]
• IgM Level [LAB72]
• IgA Level [LAB73]
• CA 125 Level [LAB155]
• C4 Complement Level [LAB151]
• C3 Complement Level [LAB152]
• Albumin Level [LAB45]
• Transferrin Level [LAB133]

Folate (aka Folic Acid) is a test that requires the patient to be fasting in order for the results be accurate. Results are falsely elevated if the patient is not fasting. Spectrum Health Laboratories recently updated our system to hard stop a test from being collected if the patient is not fasting. Please remind your patients to fast 8 hours prior to having their blood drawn.
Spectrum Health Laboratories recommends:
• No caloric or caffeine intake for 8-12 hours prior to testing. Do not eat or drink anything except normal amounts of plain water. This also includes no smoking, chewing gum, candy, cough drops, etc.
• Take normal dosages of medications unless the provider has instructed otherwise.

Due to new instrumentation at Spectrum Health Blodgett Hospital Laboratory (BIRL) and to standardize across the Spectrum Health system, we will be adopting new tests for AST and ALT. The difference between our current test and this new test is the addition of the co-factor pyridoxal phosphate (Vitamin B6). The new test is the recommended test of the International Federation of Clinical Chemistry and ultimately will provide our patient population more accurate AST and ALT results. We did not adopt the new test in the past because it came with logistical and stability issues that made its use in the lab difficult. The new instrumentation we obtained has solved some of these concerns.
Historically, if patients had a Vitamin B6 deficiency, their AST and ALT levels may have been falsely lower than the true values. This decrease was due to the lack of endogenous co-factor causing a slower reaction rate when we tested the patient sample. After we implement the new test across the system, you may notice an increase in your patient’s AST and ALT results. This increase may be evidence that your patient had some degree of Vitamin B6 deficiency. If you were trending results, we recommend you establish a new baseline with the new test versions. The lab has been changed slightly in EPIC to prevent trending between the two test versions, since the results may not be able to be correlated if your patient had a Vitamin B6 deficiency.
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.

Effective immediately, Thyroglobulin Antibody will be performed at Spectrum Health Reference Laboratory (SHRL, Grand Rapids, MI) and will no longer be a sendout to Mayo Clinical Laboratories. Collection instructions and other information may have changed, please visit the lab catalog for more information.
Thyroglobulin Tumor Marker will continue to be a sendout. If a Thyroglobulin Antibody is ordered with a Thyroglobulin Tumor Marker, then the Thyroglobulin Antibody will automatically be canceled as Mayo Clinic Laboratories will perform the Thyroglobulin Antibody as well as the Tumor Marker.

In continued pursuit of alignment, regional market hospital labs have adopted the Sysmex-Siemens automated urinalysis system. This advanced platform elevates analytical control and automation, eliminates manual steps previously required from former systems, and offers the latest in digital particle imagery. Combined with exceptional service engineer support, this system represents a notable step forward in urinalysis performance.
