Effective Jan. 29, 2020, WDL will begin in-house testing for the anti-epileptic drug CLOBAZAM (ONFI) and its active metabolite DESMETHYLCLOBAZAM. Bringing this test in-house will significantly improve turnaround time.
Effective Jan. 15, 2020, WDL will offer a new test for assessment of vitamin B12 status, VITAMIN B12 REFLEX TO METHYLMALONIC ACID. This new reflex test will be the preferred test for assessment of vitamin B12 status, replacing parallel testing of vitamin B12 and methylmalonic acid. This change aligns with current best-practices, which recommend methylmalonic acid testing only as follow up in cases of borderline deficient or low vitamin B12.
