Test Update: Chlamydia Culture Discontinued

Effective September 13, 2023, Corewell Health Laboratory will discontinue the Chlamydia Culture orderable. For patients 14 years of age and older, please order Chlamydia PCR.

• This specimen can be either a swab (genital, rectal, or throat) or a urine sample.
• The collection container is the STD-Multi-Collection Kit.
• For more information please visit: Chlamydia PCR

For patients that are under 14 years of age, a “Reference Miscellaneous Test” [LAB 848], must be ordered.

• This specimen can be either a swab (genital, rectal, or throat) or a urine sample.
• The collection container is the Aptima
• For more information please visit: APTIMA Chlamydia, NAAT, ThinPrep, Swab, Urine

As a reminder, PCR testing is also preferred for gonorrhea, when the specimen types are compatible. Continue Reading

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.

Herpes Simplex Virus PCR Update

As of April 5th, 2022, Herpes Simplex viral PCR testing will transition from being performed in the Spectrum Health Molecular department to the Microbiology department. There are no changes to the acceptable specimen sources for this test (cerebrospinal fluid and blood plasma specimens). Benefits of the new Microbiology testing method include:

• The new test method (DiaSorin Simplexa® HSV PCR) is FDA-cleared for testing spinal fluid specimens with a validated modification for testing plasma specimens. The prior method was a lab-developed test for both specimen types.

• Especially for pediatric patients, collecting sufficient specimen volumes can sometimes be challenging. The new method requires a minimum of 0.05 mL specimen per run whereas the prior method required 0.2 mL specimen.

• The frequency of testing will increase from typically one run per day to testing being performed at several times each day.

Self-Collected Swabs

Self-collected vaginal swabs may be used for testing as opposed to provider-collected swabs. Self-collected swabs are supported by current clinical guidelines as recent studies have shown their equivalence, if not superiority, in quality and their association with increased patient satisfaction.

NOTE: Self-collection must still take place in a healthcare setting and is not approved for at-home collection.
