Delay in 2C19 results


To inform all healthcare providers and clinics that from October 10, 2018 through mid-November 2018, CYP2C19 testing (Test code: 2C19) will be sent out to Mayo Laboratories for testing due to temporary non-availability of reagents from the manufacturer Spartan RX. During this period, 2C19 testing will not be performed in-house. Consequently, there may or may not be a brief delay in results for the affected test.

Effective dates: October 10, 2018 until mid-November 2018

Test name: CYP2C19 genotype test
Synonyms: Clopidogrel, Plavix

We apologize for any inconvenience this may cause, and appreciate your patience while we wait for the reagent kits to be available and for testing to resume.
