Spectrum Health Regional Laboratory is not validated to perform Chlamydia and Gonococcus testing on pediatric patients under the age of 14 years old. Testing for these patients must be sent to a reference laboratory. Please order a Reference Miscellaneous Test (#LAB848) and indicate complete test name when ordering.
Effective August 1, 2018, Spectrum Health Regional Laboratory will no longer stock Sequenom Collection Kits. If a patient presents with a Sequenom Collection Kit, our outpatient phlebotomy staff will continue to aid the patient in collection. If needed, please order Sequenom Collection Kits from the manufacturer.
Spectrum Health Regional Laboratory will still offer Panorama Collection Kits. For more information on Panorama testing please click here.
As of May 8, 2018, the following tests are no longer performed by Spectrum Health Laboratory. These tests are now available through Mayo Medical Laboratories as a send out. Please note that the specimen collection for these tests may have changed. Please check the Laboratory Catalog for collection information.
|Discontinued Test Code||Discontinue Test Name||Replacement Code||Replacement Name|
|LAB752||Clomipramine Level||LAB1230481||Clomipramine, Serum|
|LAB683||Ethosuximide Level||LAB1230480||Ethosuximide, Serum|

Effective immediately, Anti-Thyroglobulin (Anti-TgAb) requests if received in conjunction with Thyroglobulin Tumor Marker (Tg-TM) requests, will be canceled. Tg-TM tests are sent to Mayo Medical Laboratory; where both Tg-TM and Anti-TgAb are performed and resulted as part of the Tg-TM order. This is a laboratory best practice as anti-thyroglobulin autoantibodies (Anti-TgAb), which occur in 15% to 30% of thyroid cancer patients, could lead to misleading Tg results (falsely positive or falsely negative).
Questions may be directed to Dr. David Alter, using the “Contact Us” link above.
Effective November 5, 2017, the 1,25-Dihydroxyvitamin D test will have its name changed to Calcitriol (1,25-Dihydroxyvitamin D) in the Epic, Cerner and eSHare systems.
As of July 11, 2017, Spectrum Health Regional Laboratory will offer Streptococcus pneumoniae urine antigen testing. This testing is currently sent to Mayo Medical Laboratories. By bringing testing in-house, result turnaround time will be improved by 1 day, testing will be available 7 days per week (instead of Monday – Friday), and testing can be offered at a reduced charge to our patients.
Tests not performed by Spectrum Health Regional Laboratories (SHRL) will be sent to an appropriate reference laboratory. Mayo Medical Laboratories is our major reference lab; however, not all tests are performed at that location. Please refer to the laboratory test catalog for specific testing locations.

Thyroid Peroxidase Antibody (anti-TPO), Blood Level (Test #8524 )
This is the recommended test for the evaluation of Autoimmune Thyroiditis
Thyroglobulin, Tumor Marker, Serum (Test #3069)
It is only indicated for monitoring of thyroid cancer treatment.
This result is reported with an Anti-Tg result to assess for possible interference.
This test should NOT be ordered for associated anti-Tg result provided by reference laboratory.
Thyroglobulin Antibody (anti-Tg) Test
Historically ordered with anti-TPO for evaluation of possible autoimmune thyroiditis.
The literature shows that anti-TPO, alone, has better sensitivity and specificity with only 5% of cases of Autoimmune thyroiditis with anti-TPO negative, anti-Tg positive.
Since 2/2011, requests for anti-Tg have been cancelled per Laboratory Communication: Memo Thyroglobulin Antibody 2/2011
Spectrum Health Regional Laboratory Experience February 2015 – March 2016 (13 months):
357 patients with both Anti-TPO and Anti-Tg results.
*Anti-Tg results were due to concomitantly ordered Thyroglobulin TM requests.
250 patients had positive Anti-TPO and/or Anti-Tg level
193 patients had both positive Anti-TPO and Anti-Tg level
56 patients had positive Anti-TPO and negative Anti-Tg level
1 patient had a negative Anti-TPO and positive Anti-Tg levels
Based on these results, and what is reported in the literature, we are confident of our current practices and strongly request discontinuation of Thyroglobulin TM requests for the associated Anti-Tg result
