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

Laboratory supplies are filled 8 am to 5 pm, Monday through Friday. Requests made during off hours will be held until the next available day. The Laboratory Supply Department is closed on weekends and holidays. Supplies may take up to 5 days to deliver, so please place orders in advance. We cannot guarantee STAT delivery.

Self-Swab for STI Testing

Self-collected vaginal swabs may be used for STI 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.

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

New Test: COVID-19 IgG Antibody – Serology test

Effective May 18, 2020, Spectrum Health Regional Laboratory is pleased to be offering in-house COVID-19 serology testing, with initial availability 1,000 tests per day.

 

What is Serology Testing?

•  Serology testing measures the body’s immune response to COVID-19 infection in the form of antibody production against the SARS-CoV-2 virus.

•  There is a single COVID-19 serology order available in Epic, however, the Spectrum Health laboratory performs two versions of antibody testing to increase specificity and avoid reporting false positive results. An initial screen will be used to measure total antibody (IgA, IgM, and IgG), and positives will be confirmed by a second method that is specific to IgG.

•  Specificity is critical when the expected prevalence in a community is low. This serology testing is not expected to cross-react with other circulating coronaviruses that cause the common cold.

•  A positive IgG result indicates previous infection with COVID-19, but does not indicate immunity or protection against future infection.

•  This test should not be used to detect acute COVID-19 disease. Symptomatic patients suspected to have acute COVID-19 infection should be tested using a molecular assay.

•  Whether positive or negative for the presence of COVID-19 antibodies, serology testing results do not support easing of behaviors such as social distancing, wearing masks, or hand hygiene.
