If the medication has compromised the result of the drug test the sample is automatically retested using a methodology that will identify the drug type. The applicant can present a doctor's prescription for the medication that can be reviewed by the medical officer. Some medications will preliminarily test non-negative, but the confirmatory tests will rule out any non-illegal substances. Employers cannot discriminate in their hiring practices based on an applicant's use of prescription medication for legitimate medical purposes. Such discrimination could be a violation of the Americans with Disabilities Act.
Frequently Asked Questions Q: What is the turnaround time for a test result? A: Most normal negative test results are reported within 24 hours from the time the specimen reached the laboratory. Positive or abnormal tests take a few days longer due to the confirmation and verification process. Q: How much do the test supplies cost? A: All conventional test supplies are free of charge. This includes the chain of custody form, sample kits, air bills, and lab packs for shipping. Q: What are the options for receiving results? A: NTA, Inc. currently provides five means of receiving test results: by mail, phone call, fax, web, or email Q: How do I find a collection site? A: NTA, Inc. has a list of over 19,000 collection sites all over America for our clients' convenience. If there is not currently a facility in your area, we will help find a location for you. Q: How do I know that a positive result can be trusted? A: Laboratory testing procedures require the specimen to undergo an initial screening that uses a standard cut off level. If a specimen is found to have a higher concentration of the drug than the initial cut off level, it undergoes further testing to detect exact levels of the substance. Q: My employee says that she was at a party where other people were smoking pot but she wasn't. Will passive smoke make you test positive? A: The lab cut off numbers are set at a level of concentration high enough to ensure that passive smoke will not cause a positive result. Yes, she may have some level of the drug in her system, but for someone to test positive from passive smoke, they would have to be locked in a room the size of a phone booth with 5-6 people smoking marijuana for 4 hours continuously. Passive inhalation will not make you test positive.
