Enteric Pathogens PCR Panel: New Order Criteria

The Enteric Pathogens PCR test performed by Spectrum Health Laboratory may be used to detect common pathogenic bacteria and viruses in stool collected from individuals with symptoms of gastrointestinal infection. Specifically, this test detects Campylobacter, Salmonella, Shigella, Vibrio, Yersinia enterocolitica, Norovirus, Rotavirus, and the Shiga toxin virulence factor. Effective August 17, 2022, Spectrum Health’s Epic EMR will contain new ask-at-order questions to help improve the clinical decision support and appropriate utilization of this testing.

Updates to Blood Lead Reporting

As of July 19, 2022, in alignment with recommendations from the Center for Disease Control and Prevention (CDC) the reference range for blood lead testing has been updated from 5 mcg/dL to 3.5 mcg/dL.

This applies to both: Lead, Blood Level [LAB98] and Lead Screen Filter Paper [LAB2111119].

In addition, at this time the low end of reporting for Lead Screen Filter Paper [LAB2111119] has increased from 1 mcg/dL to 2 mcg/dL. Continue Reading

Discontinuation of Low-Volume and Individual Fluorescence in situ Hybridization (FISH) Probes

Effective immediately, due to low test utilization and the high cost of maintaining proficiency, the following FISH tests will no longer be offered:

• Prader-Willi/Angelman (15q11-q13) by FISH

Recommended test is Angelman/Prader-Willi mPCR

Smith Magenis (17p11) by FISH

• Williams (7q11,23) by FISH

If need arises for this test, please place an order for a Send out Genetics Miscellaneous and enter requested test in the comments. The testing will be sent out through Spectrum Health.

Any questions about referral testing may be directed to the Referral Department. Any questions or concerns regarding these changes may be directed to Dr. Salah Ebrahim in the Cytogenetics Laboratory. Continue Reading

Influenza Testing Update: April 2022

West Michigan influenza infections peaked mid-March 2022 and have been declining in the weeks that followed. Now with a low prevalence of circulating influenza, using the most sensitive diagnostic test is recommended in order to obtain accurate and actionable results. Influenza antigen testing (e.g. Sofia instrument) is no longer appropriate at this time and Influenza PCR testing should be ordered when clinically indicated.

Low Influenza
Prevalence
High Influenza
Prevalence
Recommended Order Influenza PCR (LAB3255) Influenza Rapid Antigen (LAB2111530)
or
Influenza PCR (LAB3255)

New Test: Varicella Zoster Virus (VZV) PCR, Swab

Effective February 10, 2022, Spectrum Health Regional Laboratory will offer Varicella Zoster Virus (VZV) PCR testing on swab specimens collected from cutaneous and mucocutaneous lesions (e.g. anorectal, genital, nasal, ocular, oral, skin, urethral).

PCR is the test method of choice for the diagnosis of VZV infection due to its enhanced sensitivity and speed as compared to traditional viral cultures, which should no longer be used for VZV detection. Continue Reading

Appropriate Labeling for Shared Specimen – COVID-19 & FLU AB PCR

To provide efficient and safe testing for patient specimens, please review the following information when sending COVID-19 PCR and Influenza A/B PCR testing in the same encounter to Spectrum Health Laboratories.

Two labels will be available for this testing. Labels must be fixed so that

• The test and patient information are shown
• The barcode may be easily scanned by Lab staff or instruments

When this is not done correctly, Laboratory staff removes the labels and re-fixes or re-prints it, which obstructs workflow, causes delays, and could result in patient information being peeled off. With patient safety and efficient testing being two of the Lab’s top priorities, it is vital that specimens arrive in such a way as to best accomplish both. Continue Reading

Cystic Fibrosis (CF) Carrier Screen Discontinued

Effective February 1, 2022, the Cystic Fibrosis (CF) Carrier Screen test, which includes the 23 common variants for cystic fibrosis recommended by ACOG/ACMG, will be discontinued as an orderable test at Spectrum Health Laboratory.

The recommended replacement test is the Cystic Fibrosis Mutation Analysis (Test ID: CFP) offered by Mayo Clinic Laboratories, a 106-variant panel which includes the recommended 23 common variants.
