Specimen Collection Guidelines

Laboratory test results are dependent on the condition of the specimen submitted. Positive patient identification is necessary for all samples collected. The patient must be appropriately prepared for sample collection to avoid contaminants that may affect testing results. It is important that all specimens and requisition forms be properly labeled with the name of the patient, patient's date of birth, collection date, and the origin (source) of the specimen, when applicable.

To help verify patient identification, every Regional West Laboratory Services request form has pre-numbered specimen labels (crack and peel) which provide unique patient identification. Specimens are considered mislabeled when there is a mismatch between the person-specific information on the specimen and information accompanying the specimen (e.g., computer system, requisition form, additional paperwork). When insufficient or inconsistent identification is submitted, Regional West Laboratory Services will recommend that a new specimen be obtained, if feasible.

Specimens must be collected into the correct media or container for testing. If a specimen is collected incorrectly, alternative testing will be offered, if possible. Specimens must be stored and transported at the appropriate temperature to ensure accurate test results. This information is available in the laboratory test catalog under each specific test. If there is any doubt or question regarding the type of specimen that should be collected, it is important that Client Services be contacted to clarify the order and specimen requirements.
