COVID-19 (Coronavirus Disease 2019)

 

Information updated: 07/6/2020 8:20 AM

A note to patients: Please do not contact the WSLH directly for test results. We can only give your results to the healthcare provider who sent us your specimen. They will provide you with your test result.

 

The Wisconsin State Laboratory of Hygiene (WSLH) Communicable Disease Division is currently testing for the virus that causes COVID-19 (Coronavirus Disease 2019). We use a Real-Time amplified probe-based PCR assays developed by the Centers for Disease Control and Prevention (CDC) and the TaqPath COVID-19 ThermoFisher assay. These assays have Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration. We currently only accept specimens that fit the testing criteria outlined by Department of Health and Human Services.

Testing Guidance:

The Wisconsin Department of Health Services set guidelines for specimen types acceptable for testing at Wisconsin public health laboratories. We will test patients that meet one or more of the criteria below. We encourage labs to use in-house testing whenever possible. Patients that do not meet the high priority testing criteria below may still warrant testing at another facility. For additional information of testing guidance see the Wisconsin Health Alert Network communications here.

 

Patients tested by WSLH:
  • Public Health Investigations as directed by state or local public health
  • Hospitalized patient with COVID-19 symptoms
  • Patient with COVID-19 symptoms for whom rapid diagnosis is needed to inform infection control practices
    (e.g. labor and delivery, dialysis, aerosol-generating procedures, etc.)
  • Resident of a long-term care facility with COVID-19 symptoms
  • Resident in a jail, prison, or other congregate setting with COVID-19 symptoms
  • Health care worker or first Responder (e.g. fire, EMS, police) with COVID-19 symptoms
  • Essential staff in high consequence congregate settings (e.g. prisons or jails) with COVID-19 symptoms
  • Utility workers (water, sewer, gas, electric, power, distribution of raw materials, oil and biofuel refining) with COVID-19 symptoms
  • Underserved populations with poor access to testing (e.g., underinsured, patients at Federally Qualified Health Centers, homeless patients, migrant workers, etc.) with COVID-19 symptoms
  • Post-mortem testing for a person with COVID-19 symptoms prior to death who died of unknown causes or where results would influence infection control interventions at a facility or inform a public health response. Please refer to DHS guidance.

Note: Please document the specific risk in the “Other” section on the WSLH requisition Form A where you write in your request for COVID-19 testing.

Note: If testing is needed on a patient without these indicators, please consider testing in-house or sending specimens to a reference laboratory. These specimens will not be tested or forwarded by WSLH.

 

If you have questions about COVID-19 or patient prioritization, or if you feel your patient needs urgent testing, contact a Wisconsin State Epidemiologist at WDHS.

WSLH will also report all of our COVID-19 test results to WEDSS and CDC.

NOTE: If you are performing testing, please report all results in the weekly surveillance report to WSLH.

 

Biosafety Considerations:

CDC biosafety guidance can be found at https://www.cdc.gov/coronavirus/2019-nCoV/lab/lab-biosafety-guidelines.html. We strongly encourage each laboratory to perform a risk assessment for their facility and the procedures they will perform on a suspect COVID-19 patient. After performing this risk assessment you may choose to implement additional biosafety practices, such as enhanced PPE, when working with suspect COVID-19 patients/specimens. A clinical laboratory biosafety Risk Management Program Assessment Checklist is available for use https://www.aphl.org/programs/preparedness/Biosafety-and-Biosecurity/Documents/Clinical_Lab_Assessment_Checklist_Final.pdf.

 

Testing in Your Clinical Lab:

To meet the growing need for COVID-19 testing the WSLH strongly encourages Clinical Labs to bring on NAAT testing in their labs.

 

IMPORTANT Wisconsin SEOC Survey Tool for Molecular Testing Lab Capacity https://covidlabsurvey.wi.gov

This tool is intended as a means to track molecular COVID-19 testing capacity and supply needs in the State of Wisconsin. This data will be used to inform on supply procurement strategies and resource allocation. Individual lab information will only be viewable to Public Health Agencies. Aggregate data for the State will be publicly available. Please update the information for your lab under the following scenarios:

  • Initial report to set the baseline (even if you don’t plan to test)
  • When you start testing with a new COVID-19 assay or platform
  • When you increase or decrease your testing capacity
  • To report or remove a major supply limitation affecting your ability to perform testing

Survey Results: capacity summary, instrument usage, and number of labs testing (updated every 15 min)

Frequently Asked Questions (FAQs)

Q: Are COVID-19, nCoV 2019, and SARS-CoV-2 the same thing?

A: COVID-19 stands for Coronavirus Disease identified in 2019. It is the disease caused by the virus SARS-CoV-2 formerly called nCoV 2019 or Novel Coronavirus 2019.

 

Q: Is FDA EUA clearance required to bring up an LDT for COVID-19?
A: Yes, you must either submit for FDA EUA approval or you can use an FDA EUA cleared assay produced commercially. Several commercial products have already submitted applications to the FDA for EUA clearance. Also, multiple commercial labs are offering this testing for clinical use and have FDA EUA approval.

 

Q: How much does the WSLH COVID-19 test cost?
A: COVID-19 testing is fee exempt at the WSLH. We can also provide collection kits and transportation of specimens free of charge. Please contact our Customer Service department if you need help setting this up – (800) 862-1013.

 

Q: How long will it take to get my results?
A: Our current turnaround time is 1-2 days from receipt in the lab. This is subject to test volume. If we see a large volume of testing, then testing results may be delayed.

 

Q: To whom does the WSLH report results?
A: At WSLH positive results are called to the submitting laboratory. The submitting laboratory is responsible for reporting to the ordering clinician. All positive and negative results are also reported electronically by ELR to WEDSS and faxed or sent electronically to the submitting labs. De-identified results are also reported to the CDC.

 

Q: Can the WSLH perform COVID-19 testing on residual specimens after Flu testing is performed?
A: Yes, we will test residual primary specimen even if some volume has been used for other tests. Minimum volume is 1 mL. Please maintain PCR sterility.

 

Q: Will my specimens expire if testing is not performed within 72 hours of collection?
A: Specimens will not expire while at WSLH. As long as specimen are stored 2-8 C and we receive them within 72 hours after collection, we will either test immediately or store specimens at -70C to allow for later testing. You can also freeze your specimens and ship on dry ice to ensure specimen stability.
