Accessioners help prepare specimens for lab work. As an accessioner, you receive and unpack each sample, identify which test they are used for, check for contamination, and preserve them properly. You also need to sort and catalog each item accurately to ensure nothing is misplaced or mislabeled. Laboratory technicians may request information concerning the sample and testing, so accessioners must also be knowledgeable about the kinds of samples they handle and proficient in the different types of lab tests performed by their organization. This position is also known as specimen accessioners, phlebotomists, or laboratory assistants.
