Web Tools FAQs
What are LabCorp Corporate Solutions Web Tools?
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.
How does LabCorp Corporate Solutions Web Tools save my company time?
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.
What computer skills are needed to use LabCorp Corporate Solutions Web Tools?
How does the user access LabCorp Corporate Solutions Web Tools?
What specimen information may be obtained through LabCorp Corporate Solutions Web Tools?
LabCorp Corporate Solutions Web Tools registered users are given access to data according to the user role and access rights indicated on the user registration form by the authorized company representative. Depending on user access rights, a user may view specimen status descriptions or test result information for reported specimens. Only the designated medical review officer (MRO) is able to access result information for regulated specimens.
What is specimen validity testing?
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.
Does the lab conduct SVT before screening for drugs?
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.
What methodologies does LabCorp use to perform confirmation testing?
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.
What tests are included in the LabCorp SVT panel?
At a minimum, the SVT panel includes testing for creatinine; a creatinine < 20 mg/dL reflexes to a specific gravity test. Results of both creatinine and specific gravity are used to identify dilute, substituted or invalid specimens. Tests for pH and nitrite can also be added to a panel, and are used to assess whether the physiological parameters of the collected specimen are in the expected range.
Is the nitrite test threshold based on body functions, or does it allow for infection, food ingestion with high nitrates, and water consumption with high nitrites?
The nitrite or oxidant threshold level established by the federal government is 200 mg/mL. This is based on the level at which a drug screen may be impacted by this type of adulterant and is higher than what would be expected from normal physiological processes. Nitrites or other oxidants > = 200 mg/mL are reported as “Invalid”. Specimens with nitrite levels > = 500 mg/mL are reported as “Adulterated”.
