Hi Everyone, We are Medical Laboratory, picking up specimens from many locations and transporting them to our lab via couriers. Our specimens usually contain blood tubes, urine, etc. Most of the specimens are refrigerated, some frozen and some ambient. My question is: does anyone have SOP on specimen handling while in transport? Are you using any temperature indicators inside your coolers? What is the best way to validate these coolers and make sure that specimens are transported under correct temperature? Our couriers do multiple stops so they open coolers frequently during route. Thank you, hope to hear some advices soon!
