Drug & Alcohol Test Frequently Asked Questions:

We use breath analysis and saliva testing for detecting alcohol.

Drug testing can be done by one or a combination of the following methods:  urine, hair and oral fluid (cheek swab).

Different testing methods will look for evidence of different drugs.  These is a comprehensive list of drugs that can be tested for.  If you need a specific drug tested for, please share this request with your testing professional when choosing the appropriate drug test.

Types of Drug & Alcohol Tests:

Rapid Tests – Rapid Tests Point-of-Collection Testing (POCT) provides on-site screening for drugs of abuse, urine specimen validity, and saliva alcohol following chain-of-custody protocol.

Alcohol Rapid Tests – Saliva alcohol rapid tests provide on-site screening for alcohol following chain-of-custody protocol. Missouri Onsite Testing performs saliva alcohol rapid tests in our lab or customers may also choose to perform tests in their own facilities.

Urine Tests – Standard urine drug testing panels range from five to 10 drugs. Specimen validity testing is available to detect adulterants or specimen substitution resulting from a donor’s attempts to mask drug use. Expanded profiles for medical professional monitoring are also available.

Oral Fluid Testing – Oral fluid drug testing program provides a simple method to collect chain-of-custody drug screen specimens almost anywhere. The oral fluid collection is directly observed, making it less susceptible to specimen adulteration.  The donor simply opens the sealed collection device, places it in his or her mouth, and the collector transfers the specimen into the transport tube for shipment to the laboratory.

Hair Strand Testing – A testing professional obtains a 100 milligram sample of hair (90 to 120 strands) cut at the scalp. The collector secures the hair sample in foil and completes chain-of-custody documentation in preparation for shipment to the testing laboratory. Since hair samples are obtained in full view of the collector, the process minimizes the likelihood of sample adulteration or specimen substitution.  In general, the detection time is longest in hair, followed by urine and oral fluid. Drugs in hair may be detectable for approximately 90 days, whereas drugs in urine are generally detectable for one to seven days or longer in chronic users and in oral fluid from five to 48 hours. Drug (and/or metabolite) can be detected approximately seven to 10 days from the time of drug use. This is the time in which the affected hair grows from the follicle to emerge above the scalp.

Alcohol Saliva Testing – Missouri Onsite Testing can customize a saliva alcohol testing program to meet your post-accident, random, or pre-employment testing needs. In addition, LabCorp offers laboratory-based blood alcohol testing for non-federally regulated programs.
