Starting May 17, 2023, Alverno Laboratories will switch to Quest Laboratories for reference testing, leading to changes in specimen requirements and testing methodologies. Notably, for HITRS testing, both frozen plasma from a sodium citrate blue-top tube and frozen serum, denoted before submission, are necessary. Additionally, serum nicotine testing will be temporarily referred to the reference lab. The updated Collection Manual provides detailed information on these changes, including altered specimen types, transport temperatures, and reference ranges.
