Multiple-specimen Testing

Multiple-specimen Testing

The procedures listed below are for timed, multiple-specimen tests only. All specimens are from the same patient and will be submitted to the laboratory simultaneously. Each specimen must be clearly labeled with the patient's name and the date and time of collection. Multiple-specimen labels (sequence labels) can be obtained from LabCorp. See below for ordering and labeling instructions. Only one test request form accompanies the specimens; do not submit a separate test request form for each specimen. The test request form is completed with all patient information, including any medications administered and the number of specimens submitted. The test request form and all specimens should be submitted in one container (box or plastic specimen transport bag). Each result will be identified on the report by the corresponding specimen sequence numbers, associated times, or draw site(s) supplied. See the Comprehensive List of Procedures for additional individual test information.

Note: For best results, when viewing the table below in Internet Explorer®, users should unselect Compatibility View under Compatibility View Settings (Page or Tools Menu).

Labeling Multiple-specimen Submissions

Labels (Multispecimen Panel) can be ordered from LabCorp using item Nº 3715. These labels, orange in color, are available in a pack containing five sheets with a total of 600 labels. Sequence labels will be applied at the top of the specimen tube, just below the tube's top or cap (see following diagram for correct orientation). This places the label away from other labels on the tube and should prevent it from being covered up by bar codes, accession labels, etc. Room is available on the label so that a sequence number (eg, #1, #2, etc), collection time (eg, 8 AM, 9 AM), time description (eg, fasting, 30 minutes, etc), or the description of a draw site (eg, in renal vein sampling, an abbreviation such as IVC) may be written.

Frozen Gel Packs. To ensure specimen integrity during warm weather, follow these Instructions for Use of frozen gel packs and specimen lockboxes.
