Weather Impact on Send Out Testing

We want to inform you about an important update regarding T-Spot test collections and deliveries. Due to severe weather conditions expected to affect parts of the United States, we have been advised by our reference laboratory to suspend the collection and sending of this test on Monday, February 17 after 3 p.m. through Tuesday, February 18. Testing collection will begin again on Wednesday, February 19th, unless the request is extended.

This precaution is necessary to ensure the safety and integrity of the specimens, as well as to avoid any potential delays or issues that could arise from the adverse weather. We appreciate your understanding and cooperation during this time.

• Please be sure to place a collected order in Epic or your EMR, or include a paper order with the specimen.

• Please make sure the specimen is labeled with 2 patient identifiers, date and time of collection, and source (nasopharyngeal or nares)

For all other options please visit: Corewell Health COVID-19 screening and testing

Updated Advanced Beneficiary (ABN) Statuses (Corewell Health Epic Users)

On Tuesday, Jan. 7, you will see changes to the ABN Status list in Epic, making it easier to select the appropriate status from available options.

In an effort to optimize workflows, the ABN statuses in Epic have been changed to be more efficient. Some statuses have been removed based on volume of use and feedback from clinicians. Other options have been changed to ensure clarity after review by Informatics, Compliance, and Revenue Cycle. The information below lists the new options and when to use them. Please refer to Epic Proportions for more information.

Attention providers: to reduce your ABN workflow burden, please select one of the first two Provider ABN statuses at the time of order entry only. The collection of signed ABN waivers will occur later by office, laboratory, or imaging staff using the three ABN Signed statuses when the specimen is being collected or when the imaging procedure is being performed. If your office routinely collects laboratory specimens, please instruct your staff to collect ABN signature waiver at the time of specimen collection.

Status Options Available after January 7, 2025:

  • Provider: ABN Discussed. Await Signature. [205] = Providers placing orders when the patient is present to discuss ABN, select this option. This allows the provider to place the order while also allowing lab or radiology staff the ability to complete their process as usual later and avoid the need for a new order. Patient will sign during lab/imaging procedure.
  • Provider: ABN Not Discussed. Patient Not Present. [206] = Providers placing orders when the patient is not available or present, select this option. This allows the provider to place the order while also allowing lab or radiology staff the ability to complete their process as usual later and avoid the need for a new order. Lab/imaging will need to discuss ABN and sign.
  • ABN Signed, Service Accepted (Option 1 – Bill Medicare) [3] = This status indicates that a patient has signed the form, wants to receive the service, and agrees to be financially responsible for the service if Medicare does not pay. This option should only be used by the person who is presenting the ABN to the patient for signature.
  • ABN Signed, Service Accepted (Option 2 – Do not Bill Medicare) [9] = This status indicates that a patient has signed the form, wants to receive the service, agrees to be financially responsible for the service, and agrees not to bill Medicare. This option should only be used by the person who is presenting the ABN to the patient for signature.
  • ABN Signed, Service Declined [6] = This status indicates that a patient has signed the form and does not want to receive the service. Typically, the clinician cancels the order in this situation. If a patient signs the form and declines the service but the physician believes it is important to proceed with the service at Corewell Health’ expense the test should not be canceled.
  • Notice Printed [2] = This status is automatically assigned to an ABN when the ABN is printed. In practice, “ABN Printed” can function as either an initial or intermediate status, because staff can print a copy of the ABN before or after presenting the form to the patient.
  • Notice Triggered [1] = This status is automatically assigned to new ABN forms. Indicates an ABN warning has been prompted. The order/procedure will NOT be able to be signed when the ABN is in this state.

Influenza Antigen Testing (December 2024)

Influenza prevalence fluctuates seasonally, and case numbers are currently increasing throughout West Michigan. The onset of “flu season” varies year-to-year though typically begins its upswing in the month of December. It is important for providers to have an awareness of influenza prevalence (in addition to other respiratory viruses) to help guide when influenza testing should be pursued.

The use of point of care (POC) antigen testing reduces both the cost to the patient and turn-around-time as compared to lab-based molecular methods. POC antigen tests are typically available for COVID-19, influenza A/B, and as a COVID-19/influenza A/B combination test. During warmer months when influenza prevalence is negligible yet COVID-19 may be circulating, a COVID-only antigen test may be helpful for diagnosis. As influenza increases into colder months, a COVID-19/Influenza A/B combo test would act as a screen for both viruses.

POC tests generally have high analytical specificity but lack the sensitivity of nucleic acid amplification methods (e.g. PCR). For this reason, PCR testing is still recommended for hospitalized patients and for outpatients with a negative POC result if influenza is still suspected and if the result will impact clinical decision making. Influenza PCR may be ordered as a standalone test (LAB3255) or as a part of a panel alongside COVID-19 and RSV (LAB1230746).

 

Test Information

  • Influenza PCR Epic Code: LAB3255, Interface EMR Code: 11594, CPT Code 87502
  • COVID-19, Influenza A/B, RSV PCR Epic Code: LAB1230746, Interface EMR Code: 1230746, CPT: 0241U

Update: Platelet Aggregation Studies Scheduling

Effective immediately, platelet aggregation testing will require a pathology consult prior to scheduling for testing performed at Corewell Health Reference Laboratory West, Grand Rapids. This consult request must be completed prior to scheduling the patient for testing.

After consultation the testing may be ordered and scheduled.

As a reminder testing is performed for scheduled patients Monday – Thursday from 7:30 am-9:30 am at the 35 Michigan Street Laboratory. Patients should be resting, fasting, non-smoking, and should not be pregnant. Patients should avoid taking any prescription or over the counter medications known to affect platelet function for ten (10) days to two (2) weeks prior to the test.
