On May 17, 2017, the US Food and Drug Administration (FDA) issued a safety communication warning against using venous samples on Point of Care Magellan Diagnostics LeadCare Testing System devices (LeadCare, LeadCare II, LeadCare Plus, and LeadCare Ultra). Venous specimens appear to be at risk for having falsely low results. Only Capillary (“finger stick” or “heel stick”) specimen types should be used.
IF YOUR OFFICE IS USING ANY OF THE MAGELLAN LEADCARE TESTING SYSTEM DEVICES: please DISCONTINUE the use of VENOUS specimens for testing.
Effective September 12, 2016, Spectrum Health Regional Laboratory (SHRL) will update the methodology for Vitamin D 25 Hydroxy Level (25-OH Vitamin D) from LCMS (Liquid Chromatography-Mass Spectrometry) to automated immunoassay.
Numerous 1,25-Dihydroxyvitamin D (1,25(OH)2D) requests are received daily (1200 in 2015). This is not the standard test for Vitamin D status. 1,25-Dihydroxyvitamin D testing should be reserved for patients with renal disease, sarcoid, tuberculosis, lymphoma and rickets, as well as, long term use of protease inhibitors, glucocorticoids, or anticonvulsants. Vitamin D 25 (25 OH D) level is sufficient in most cases. The number of requests and review of the ordering providers raises a concern that a number of these requests were ordered inappropriately.
In an effort to decrease the number of potential improperly ordered tests and consequently decrease unnecessary costs to patients, insurance companies, and the laboratory, please review your individual ordering practices.
In the near future, this test name will be changed to “Renal 1,25 Dihydroxyvitamin D” to better reflect its appropriate utilization.
Any questions concerning Vitamin D testing may be directed to the Pathology Department.
