On Wednesday, December 9th, Natera is offering a webinar on the advantages of SNP-based method in prenatal screening for twins.
Join the 25 minute webinar to learn:
- What do the ACOG and ISPD recommendations say about using NIPT for twins?
- What unique capabilities of Panorama in twin pregnancies are highlighted in these recommendations?
- How can Panorama’s capabilities help you better manage twin pregnancies?
- How accurate is Panorama in detecting aneuploidy and other features important to twins?

Effective immediately there has been an update to scheduling breath testing. Both the Bacterial Overgrowth and Lactose Intolerance breath tests must be scheduled through Epic or via Spectrum Health MyChart app.
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.
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.
As of August 26, 2020, the following tests will be obsoleted or made as lab orderables only. This was implemented to streamline protein electrophoresis orders and ensure that patients receive the recommended testing for the assessment of plasma cell proliferative diseases.
In addition to streamlining protein electrophoresis orders, order questions have been implemented to the available tests to access the reason for ordering to ensure that the proper reflex testing is applied.
For more information, see the lab test directory under the available tests for a protein electrophoresis orders tip sheet entitled “Orders- Protein Orderable Changes”
Leaky specimen containers may cause compromised test results and it is also a hazard to lab couriers and registration personnel. Leaky specimen containers are not acceptable and may be rejected.
In order to prevent leaky containers, please be sure to:
Pay close attention to the lid, making sure the screw-cap lids are fastened evenly and securely, with the threads aligned. If a patient has challenges with tightening the lid, please have them notify lab staff when they return to drop off their container.
Containers should be upright at all times, with lid on the top during transport. If container is placed in a biohazard bag, please maintain in the upright position by gripping the cup or the handle and not by the top of the bag.
The Laboratory provides a brochure “Laboratory Specimen Home Collection” for patient collection instructions. Internal offices (i.e. SHMG) may order these from Document Services using the order number X17776 (X19611 for the Spanish version). External offices may order these from Laboratory Courier Services using the Supply Order Form.
Beginning September 8, at approximately 2PM, Spectrum Health Laboratories will go live with their new lot of APTT reagent. This lot change triggered a new therapeutic curve resulting in new heparin nomograms for the system. The standard heparin therapeutic range will change from the current 45-65 seconds to a new range of 37-52 seconds based off the new curve. Reference ranges for the APTT assay will also be updated. Grand Rapids APTT reference range will be 21-27 seconds and the Regional Hospitals will be 21-31 seconds.
APTT specimens that are unable to reach an endpoint (no clot is detected), will reflex to the Unfractionated Heparin (UFH) (Test Code LAB3389) anti-Xa assay. To accommodate this change, UFH values have been added to heparin nomograms. The UFH anti-Xa assay is currently only performed in the Grand Rapids labs and valid only for unfractionated heparin. Any questions concerning these changes may be directed to the Spectrum Health Regional Laboratory Coagulation department at 616-267-2740.
Please read below for Labor Day holiday hours for the following departments in the Laboratory:
- Referrals Department (Spectrum Health Regional Laboratory, Grand Rapids)
- Outpatient Draw Sites (Outpatient Phlebotomy)
- Flow Cytometry Laboratory (Advanced Technology Laboratory, Grand Rapids)
Test manufacturer supply chains continue to be disrupted due to COVID-19. Currently, there is a shortage of supplies for the Group B Streptococcus PCR test. Orders for this PCR test may continue to be placed, however, the SHRL Microbiology Department will perform a culture method until PCR supplies are available with appropriate charging and a reporting comment indicating that the culture was performed. The PCR test is normally resulted within 24-48 hours of specimen receipt in lab, whereas the culture method turnaround time may be 48-72 hours. An update will be posted when these PCR supplies are received, however, there may continue to be intermittent supply issues for this test. Additional test information can be found here.
