Drug Screen, GCMS, Urine (HCTUPNL) Toxicology Lab Test

Name: Drug Screen, GCMS, Urine

Test Name: Drug Screen, GCMS, Urine

Health Link Test Code: HCTUPNL

LIS Test Code: TUPNL

CPT Code(s): 80307 or G0659

Included In: Procedure Panel: Drug Screen, Urine Comprehensive [HCMSUPNL]

Methodology: Gas Chromatography/Mass Spectrometry

Days Performed: Mon-Fri, dayshift.

In-Lab Turnaround Time: 3 - 5 days.

Specimen: Random urine

Collection Container: Sterile screw cap container

Collection Instructions:

Drugs suspected and known medications should be indicated. The laboratory strongly favors direct communication between the primary physician and the laboratory. Since the drug screen is a search for the presence of an unknown drug, any drug-related patient history communicated to the laboratory will give the analyst a point of direction in the testing of the sample and help expedite return of results.

Collection Volume: 25 mL

Stability Ambient:

3 days

Stability Refridgerated:

7 days

Stability Frozen:

1 year

Sample Analyzed: Urine aliquot

Testing Volume: 10 mL

Pediatric Testing Volume: 7 mL

Specimen Transport:

Transport specimen to laboratory. Transport with coolant pack if coming from clinic location.

Additional Information:

The Comprehensive Drug Screen simultaneously screens and confirms the presence of over 100 drug substances and drug metabolites in human urine by GC/MS. Report consists of immunoassay screening results and a list of drugs detected and definitively identified by GC/MS. Certain commonly encountered drugs such as morphine, hydromorphone, alprazolam, triazolam, and oxazepam may not be detected by GC/MS because they exhibit poor chromatographic properties. However, these drugs will give presumptive positive immunoassay screening results for the benzodiazepine or opiate classes. Certain toxic substances such as LSD, cannabinoids, alcohols, insecticides, cyanide, carbon monoxide, salicylic acid, water soluble drugs such as diuretics and many other chemicals and drugs are not detected by this procedure.
