We recommend that you send your sample with Fed-Ex or UPS. Fecal samples for fecal alpha1-Proteinase Inhibitor need to arrive frozen at the laboratory. We highly recommend shipping such samples overnight on dry ice.
Serum TLI and PLI are stable for up to 2 weeks at room temperature. We recommend that samples for serum cobalamin/folate analysis are shipped overnight either frozen or at least with included ice packs to keep them cooled during shipment.
Note: Due to delivery procedures at such a large university, packages sent with the US Postal Service can often be delayed or even lost within departments. Please DO NOT use the US Postal Service as a carrier. We also offer a Fed Ex discounted shipping program through our website. Contact the lab for your username and password.
