This January we are celebrating the National Thyroid Awareness Month. In United States of America, it is estimated that approximately 20 million people have thyroid disease and most importantly, according to the American Thyroid Association (ATA) as many as 60% of people suffering from a thyroid disorder are not aware they have it.The thyroid is a butterfly shaped-gland located at the front of the neck that produces and release thyroid hormones (See Figure 1).
Figure 1. Thyroid Gland Anatomy and Histology
It regulates important physiological functions as:
-
- Breathing
- Heart rate
- Energy production
- Muscle strength
- Body temperature
- Weight
- Mood
Thyroid disease can present in two main forms:
- Hypothyroidism (under functioning thyroid)
- Hyperthyroidism (over functioning thyroid)
Confirmation or exclusion of thyroid disease requires a clinical examination combined with biochemical determination of thyroid hormones (TH) and thyrotropin (TSH)concentrations.
In this blog we discuss the best practices for ordering thyroid function tests for the initial screening of thyroid disease at Corewell Health.

Lab Specimen Label Printing Update for Corewell Health Epic Users
On 10/31/23, a change was made to lab specimen labels, which included a patient’s preferred name on the label, if it is documented in Epic. This highlighted a change in the names of label types seen by staff when reprinting specimen labels in Epic. Due to a mix of Intermec and Zebra printers across the entire Corewell Health system, defaults needed to be removed from Epic build to account for these differences. Users will now be required to manually choose the correct label type when reprinting labels. The Collection Activity behavior should remain the same.
As a reminder, referral testing, tests that are sent to another laboratory to perform, is dependent on the weather. Inclement weather can affect both the turnaround time of testing, and the testing capabilities of the organization. Our referral testing is dependent on outside transportation facilities (such as FedEx and UPS). When those organizations face challenges in weather, our testing capabilities must remain flexible.
If there is inclement weather in and around Memphis, TN (the main FedEx hub), there may be delays and cancellations of testing. We will try our best to communicate these changes as soon as possible via our blog: https://lab.corewellhealth.org/

Effective January 17, 2024, UFH Anti-IIa testing will be performed at both Corewell Health Reference Laboratory West and Blodgett Immediate Response Laboratory in Grand Rapids.

Influenza cases numbers are currently increasing throughout West Michigan. Influenza prevalence guides the most appropriate testing approach and sufficient prevalence has now been reached for influenza rapid antigen or point of care testing (e.g. Sofia instrument) to have improved performance. The use of point of care testing as a screening method during high prevalence reduces both the cost to the patient and turn-around-time as compared to lab-based molecular methods. Point of care 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 result if influenza is still suspected and if the result will impact clinical decision making.
| Low influenza prevalence | High influenza prevalence | |
| Recommended order | Influenza PCR | Influenza Point of Care Testing or Influenza PCR |
In pursuit of best practice and alignment, as the only regional laboratory performing Legionella Antigen testing, Corewell Health Ludington will be consolidating this low volume testing by sending it to our core lab.
Beginning January 1, 2024, all specimens for Legionella Antigen, Urine testing collected at Corewell Health Ludington sites will be sent to Corewell Health Reference Laboratory West in Grand Rapids for testing. All other details regarding the test remain the same.

Genetic Testing Informed Consent
Submission of an order for any predictive genetic tests and pre-symptomatic genetic tests, as defined by MCL 333.17020, contained in Corewell Health laboratory catalog constitutes certification to Corewell Health Laboratories that the ordering physician understands that written, informed consent is required for these tests and that, by submitting an order for these genetic tests, ordering physician has obtained “Informed Consent” of subject patient as required by any applicable state or federal laws with respect to each test ordered. On occasion, we forward a specimen to an outside reference laboratory. Corewell Health laboratories may request that ordering physician provide such consent to Corewell Health upon a reasonable request.
