Instructions

NOTE: This test is only offered to patient’s that are unable to produce urine, i.e., Transplant patients. Urine testing is the preferred source for drug screening, (please see Comprehensive Drug Analysis with Confirmation).

This assay screens for the following drugs:

Amphetamines Barbiturates Benzodiazepines Buprenorphine / Norbuprenorphine Cannabinoids Cocaine and Metabolites

Methadone Methamphetamines Opiates Oxycodone Phencyclidine

 

 Positive screen results are automatically confirmed.

Specimen Collection Criteria

Collect (preferred specimen): Two plain Red-top tubes.
Also acceptable: Three Lavender-top EDTA tubes or three Green-top Sodium Heparin tubes.

Do not use Serum Separator Tubes.

Physician Office/Draw Specimen Preparation

Centrifuge to separate serum or plasma from cells within two hours of collection. Transfer serum or plasma to a plastic transport tube and refrigerate (2-8°C or 36-46°F).

Preparation for Courier Transport

Transport: 4.0 mL serum or plasma, refrigerated (2-8°C or 36-46°F). (Minimum: 3.0 mL)

Rejection Criteria

• Serum Separator (SST) tubes.
• Specimens not collected and processed as indicated.

In-Lab Processing

Centrifuge to separate serum or plasma from cells within two hours of collection. Transfer serum or plasma to a plastic transport tube and refrigerate (2-8°C or 36-46°F).

Transport: 4.0 mL serum or plasma, refrigerated (2-8°C or 36-46°F). (Minimum: 3.0 mL)

Storage

Specimen Stability for Testing:

Room Temperature (20-26°C or 68-78.8°F): 7 days
Refrigerated (2-8°C or 36-46°F): 14 days
Frozen (-20°C/-4°F or below): 3 years

Specimen Storage in Department Prior to Disposal:

Test Methodology

Qualitative Enzyme Linked Immunosorbent Assay/Quantitative Gas Chromatography-Mass Spectrometry/Quantitative Liquid Chromatography-Tandem Mass Spectrometry.

Clinical Utility

Many patients in renal failure cannot produce urine in sufficient amounts to permit a conventional Comprehensive Drug Analysis. An alternative is to perform a screening procedure on serum. Please note that urine provides the greatest opportunity to detect and identify an illicit substance and use of this blood screening procedure for other than Pre-Transplant patients is forbidden. This is a sendout test and immediate results are not obtainable. This test is not available on a STAT basis.
