New Tests: Trichomonas PCR, Mycoplasma genitalium PCR, and STI Panel (Alinity)

New Test Announcement

Corewell Health Advanced Technology Laboratory is pleased to announce the addition of Trichomonas, Mycoplasma Genitalium (Mgen), and STI Panel testing on the Alinity m platform.

As of 1/5/2023, Trichomonas vaginalis (TV) and Mycoplasma genitalium (MG) STI tests are available using the Alinity m collection kit and a panel which includes the above plus Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG).

All four tests may be run on one urogenital sample, saving cost and time, and reducing human error.

Inform: RSV Testing – Age Restrictions

Respiratory syncytial virus (RSV) primarily infects pediatric patients, but occasionally infects adults and may be of particular concern for the elderly and immunocompromised. Corewell Health Laboratories offers two tests for RSV. A rapid antigen test may be used to confirm RSV diagnosis in pediatric patients. This test is not approved by the FDA for testing adult patients, so tests will be cancelled if ordered on an off-label age group. There are no age restrictions for RSV testing by way of a molecular panel that also includes COVID and influenza as viruses with overlapping symptoms.

Test name Epic Test ID Methodology Specimen Age restriction
RSV Rapid LAB495 Antigen Nasopharyngeal (NP) swab Approved for patients 0 – 18 years of age
COVID, Influenza, RSV PCR LAB1230746 Molecular/PCR Nasopharyngeal (NP) swab No age restriction

Influenza Testing Recommendation (November 2022)

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 testing (e.g. Sofia instrument) to have improved performance. The use of rapid antigen 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. Rapid antigen 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 antigen result if influenza is still suspected and if the result will impact clinical decision making.

Update: Complete Blood Count (CBC)

Starting November 29th, 2022, Corewell Health West, Hematology Laboratories will begin reporting absolute counts for white blood cell (WBC) manual differentials, in addition to relative (percentage) counts. The WBC differential count determines the number of each type of white blood cell present in the blood. It can be expressed as a percentage or as an absolute value. Of these, the absolute value is much more important than the relative value, given that clinically relevant WBC elevations and declines are defined by their absolute numbers, not by their relative proportions, and there is potential for error if this conversion is performed outside the laboratory.

Positive COVID-19 PCR Communications

At the beginning of the COVID-19 pandemic Spectrum Health Laboratory implemented a protocol to call providers and patients to notify of positive COVID-19 PCR testing.  The pandemic has shifted to an endemic phase and a positive COVID-19 test is no longer considered a critical value. Effective Friday, August 26, 2022, Spectrum Health Laboratory will no longer call positive COVID-19 PCR testing, for inpatient or outpatient specimens.

Results for COVID-19 PCR will still file to the patient’s chart in Epic and reported to the ordering provider through usual means of receiving results (fax or electronic) and to the Michigan Department of Health and Human Services (MDHHS). Patient’s will still be notified via their MyChart as well.
