Reminder: Thin Prep Collection

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.

New Test: HPV High Risk Screen with HPV Genotype Reflex

Effective August 26, 2024,  Corewell Health Laboratories West will be updating their High-Risk HPV testing.  The new assay will be performed on the Abbott Alinity m at Corewell Health Reference Laboratory West, Grand Rapids.  Testing will now automatically include HPV Genotype results whenever HPV is detected.  There will no longer be a separate charge to the patient for HPV Genotype testing.

There will also be an expanded number of High-Risk HPV Genotypes reported:

  • HPV Genotype 16
  • HPV Genotype 18
  • HPV Genotype 45
  • HPV Genotype 31/33/52/58
  • HPV Genotype 35/39/51/56/59/66/68

The new assay is FDA approved for Primary screening in addition to co-testing.

Post hysterectomy vaginal specimens will still be a send out test (LAB1230722). Continue Reading

Microbiology

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.
