Influenza Testing Reminder

The mitigation strategies enacted during the COVID-19 pandemic to reduce the spread of this virus have also impacted the transmission of other respiratory viruses. Influenza is typically prevalent during the winter months (December through March), however, influenza cases were essentially non-existent during the 2020-2021 season and influenza is not currently circulating in our community.

In the absence of circulating influenza activity, it is recommended to use the most sensitive diagnostic test in order to obtain accurate and actionable results. Influenza antigen testing (e.g. Sofia instrument) is not appropriate at this time. More detailed information can be found as published by the CDC: Algorithm to assist in the interpretation of influenza testing results and clinical decision-making during periods when influenza viruses are NOT circulating in the community

Hemostasis/Coagulation

Update: PT/INR Resulting Change

The Spectrum Health Laboratory Coagulation Department announces the following changes occurring on 6.29.21 because of new instrumentation:

• New coagulation instrumentation will go-live on 6.29.21.

• This new instrumentation will align the Spectrum Health Regional Laboratory (in GR) with current Regional/Blodgett reportable upper limit for Protime/INR results.

• The current Protime (PT) upper limit of 120 seconds will change to 90 seconds. Any result that is greater than 90 seconds, will be reported as >90 seconds.

• The current INR upper limit of 12.0 will change to 8.0. Any result that is greater than 8.0 will be reported as >8.0.

Any questions can be directed to the Spectrum Health Regional Laboratory Coagulation Department using the Contact Us link above.

Update: COVID-19 Swab Supplies

If you are collecting COVID-19 swabs in your office or clinic, please order and collect using the saline swab kits (“liquid media” or “wet collection”) instead of the tube with no liquid media (“dry collection”).

• Liquid media swab kits will provide a faster turn-around time.

• Dry collection kits supplies are low.

Please refer to the COVID-19 PCR test in the Lab Catalog for the most up-to-date information on COVID-19 collection.

COVID-19 PCR Swab – LAB1230607

RESOLVED-Update: STD Testing Supply Shortage

As of 5/18/2021 – Production of collection kits is no longer limited. Please resume normal ordering practices. 

There is a national shortage of testing and collection material for Chlamydia Trachomatis (CT) and Gonococcal (GC) infections. Spectrum Health is currently experiencing difficulties obtaining collection kits to perform the testing for all methods.

Resolved: Change in testing for Lyme Total Antibody

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. Continue Reading

Obsoletion of Mayo Send-Out Test Influenza Virus A/B Antibodies, IgG and IgM

As of October 29, 2020, the following send-out tests will be will become obsoleted due to lack of clinical utility:

SFLA Influenza Virus A Antibodies, IgG and IgM (Separate Determinations), Serum [LAB802]

SFLB Influenza Virus B Antibodies, IgG and IgM (Separate Determinations), Serum [LAB803]

For diagnosis of acute Influenza infection the following molecular tests are recommended:

Influenza A/B PCR [LAB3255]

Influenza A/B Rapid [LAB9240]**

Influenza A/B Rapid, Influenza A/B PCR if Negative [LAB2111530]**

**Available only at regionals and during times of high flu incidence Continue Reading
