The semen specimen container must be labeled with at least two identifiers. The information to identify the specimen must be unique to the patient so that results are not associated with the wrong patient. Positive identification may include first and last name and unique numbers, such as a medical record number, hospital number, or the patient's birthdate. Once the patient has been registered in the laboratory's computer system, printed labels containing identifying information can be used to ensure positive identification of all aliquot containers, microscope slides, and counting chambers used for the semen analysis.
