Web Tools FAQs

LabCorp Corporate Solutions Web Tools are a suite of web-based applications that enables customers to view specimen status and final results, retransmit specimen results, view laboratory-scanned chain of custody (COC) form images, and register donors for drug screen specimen collection at a Web COC-capable site. LabCorp Corporate Solutions includes the Web COC tool that guides specimen collectors through each step of the collection process to produce a non-federally-regulated COC form on-site.

The LabCorp Corporate Solutions Web Tools inquiry functions reduce time spent contacting the laboratory for specimen status, chain of custody form copies, and retransmission of results. The Web COC electronic specimen collection application eliminates the need to order or stock pre-printed non-federally-regulated chain of custody forms for urine, hair, oral fluid, and rapid drug tests. LabCorp Corporate Solutions' Web COC collection process provides real-time negative rapid drug screen results so that employers can make same-day hiring decisions. LabCorp Corporate Solutions takes the guesswork out of drug test collections status with the donor registration function, including email notification of specimen collection completion or donor no-show.

Specimen validity testing (SVT) is performed on a urine drug screen specimen to detect substitution, adulteration, or dilution. See the Drugs of Abuse Reference Guide for additional information on SVT. Use of a Medical Review Officer is recommended to evaluate out of range SVT results.

  • Substitution - Submission of a specimen that is not characteristic of human urine. Typically, this may be water or water with salt in it and is identified by extreme creatinine and specific gravity results.
  • Adulteration - Adding a substance to a specimen after it has been collected. The product added is designed to mask the presence of, or chemically destroy, the drug or drug metabolite that the specimen may contain. An adulterant product may be added with the intention of adversely affecting the testing reagents.
  • Dilution - Result of ingestion of large amounts of water typically just before urine donation or as a result of physiological conditions. If drug/metabolites are diluted to a concentration below the initial test cutoff, a dilute urine may result in a false negative.

No, specimen validity testing is performed simultaneously with the initial drug screens. Depending upon the drug screen and the specimen validity results, the laboratory will release (1) both the drug screen and the specimen validity test results, (2) the specimen validity test results only, or (3) the drug screen results only.

Gas chromatography/mass spectrometry (GC/MS) and liquid chromatography with tandem mass spectrometry (LC/MS/MS) are the methods LabCorp uses to confirm presumptive positive drug screens. These mass spectrometric methodologies provide identification of the molecule(s) based on characteristic fragmentation patterns at specific retention times. GC/MS and LC/MS/MS are hyphenated techniques, utilizing a gas or liquid chromatograph coupled to single- or multiple-stage mass spectrometers.
