High sensitivity flow cytometry testing for paroxysmal nocturnal hemoglobinuria (PNH) is a test done on patient’s peripheral blood to screen for the presence or absence of PNH clones and/or to follow PNH clonal populations. The lower limit of detection of a PNH clone for the Spectrum Health laboratory has been validated as 0.01% (1:10,000) for red cells, 0.01% (1:10,000) for granulocytes and 0.1% for monocytes (1:1000).
The results from PNH flow cytometry testing can guide the clinical team in classifying a patient’s disease appropriately, analyzing the risk of disease progression, and choosing appropriate testing to monitor response to treatment. Therefore, the PNH flow cytometry test result will now include a pathologist’s interpretation based on the new recommendations given in Updated ICCS/ESCCA Consensus Guidelines for the Clinical Utility of Testing for GPI-Anchor Deficient Clones in Paroxysmal Nocturnal Hemoglobinuria (PNH) and other Bone Marrow Disorders (Accepted article by Dezern and Borowitz, doi: 10.1002/cyto.b.21608).

Effective immediately, Anti-Thyroglobulin (Anti-TgAb) requests if received in conjunction with Thyroglobulin Tumor Marker (Tg-TM) requests, will be canceled. Tg-TM tests are sent to Mayo Medical Laboratory; where both Tg-TM and Anti-TgAb are performed and resulted as part of the Tg-TM order. This is a laboratory best practice as anti-thyroglobulin autoantibodies (Anti-TgAb), which occur in 15% to 30% of thyroid cancer patients, could lead to misleading Tg results (falsely positive or falsely negative).
Questions may be directed to Dr. David Alter, using the “Contact Us” link above.

Influenza is currently widespread throughout the nation at epidemic proportions. During influenza epidemics, clinical assessment predicts the presence of influenza infection virtually as well as laboratory testing. Therefore, it is no longer necessary to perform viral testing on ambulatory patients who present with illness consistent with influenza before beginning antiviral treatment. Antiviral treatment for Influenza should be started as soon as possible to have a beneficial effect.
Shortages of supplies and medications frequently occur during Influenza epidemics. However, diagnosis of specific viral respiratory infection remains important for hospitalized patients.
Please follow the current recommendations:
- Limit availability of viral transport media at ambulatory sites.
- Emergency departments are to limit viral respiratory testing to patients expected to be admitted.
- Do not perform testing for test of cure.
Thank you for your support during this time. Please direct any questions to Laboratory Services via the “contact us” link above.

Be advised that this process may take up to 30 minutes to complete the draw using our inpatient phlebotomy staff.
We request that all routine blood draws return to one of our convenient Outpatient laboratory locations during normal business hours. Most laboratory locations are open Monday to Friday from 7 a.m. to 5 p.m. We recommend that if there is a question regarding hours of operation to contact the draw site.
