Effective March 12, 2025, Corewell Health Laboratories will update the STI testing process for patients under 14 years old. These tests will now be sent to Children’s of Wisconsin Laboratory, aligning with the current in-house testing methods for patients 14 years and older using the Alinity m multi collection tube. Previously, these tests were sent to Quest Diagnostics Laboratory using the Aptima® collection device. Please discontinue use of Aptima® collection devices on March 12, 2025.

With the August changes to STI testing Corewell Health Reference Laboratory West has seen an influx of incorrect orders. As a reminder, not all STI testing can be performed off of a Thin Prep® specimen. The STI Panel includes four different tests: Gonorrhea PCR, Chlamydia PCR, Trichomonas PCR and Mycoplasma Geniltalium PCR (Mgen). Unlike the other testing, Mgen cannot be added on to the Thin Prep® container.
If an STI Panel is ordered and the only specimen that is collected is a Thin Prep®, laboratory staff will independently cancel the STI panel and reorder the three tests that are able to be completed off of the specimen that is submitted. If an Mgen test is still needed, please submit a separate urine or swabbed collection using the Alinity -M collection kit.
Beginning August 26, 2024, Corewell Health Laboratories (West and South) will begin updating instrumentation for STI and HPV testing. Aptima collection devices will no longer be available except for pediatric patients under 14 years old.
To order the new swabs:
- Corewell Health and CHMG, please order via Workday ITM-1190747 as you run out of Aptima devices until the cutover date. (August 26th for West, late September for South)
- Independent Offices or other non-Corewell Health Sites, please use the Supply Form and continue to order STD multi-collection kit or ThinPrep Pap Container.
Please use for pediatric patients or discard any unused APTIMA kits. Please review the link below for images:

New Tests: Trichomonas PCR, Mycoplasma genitalium PCR, and STI Panel (Alinity)
New Test Announcement
Corewell Health Advanced Technology Laboratory is pleased to announce the addition of Trichomonas, Mycoplasma Genitalium (Mgen), and STI Panel testing on the Alinity m platform.
As of 1/5/2023, Trichomonas vaginalis (TV) and Mycoplasma genitalium (MG) STI tests are available using the Alinity m collection kit and a panel which includes the above plus Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG).
All four tests may be run on one urogenital sample, saving cost and time, and reducing human error.
Test Update: Chlamydia and Gonococcus Testing (Alinity m)
Effective October 31, 2022, the Advanced Technology Laboratory’s Molecular Diagnostics Department will accept oropharyngeal and rectal swab specimens as testing sources for Chlamydia and Gonococcus testing using the Alinity m multi-Collect Kit. This specimen type is FDA approved on the Alinity m platform.
NOTE: Specimens collected on patients under the age of 14 or collected for Child Protective Services, will still be sent out to a reference laboratory.
Beginning October 1, 2022, Spectrum Health Laboratory will update the current Chlamydia and Gonococcus testing using Abbott multi-Collect kit and Abbott m2000 platform to the Abbott Alinity m multi-Collect kit and Alinity m platform. This platform update will include an orderable name change and change in collection materials.
