Frequently Asked Questions

The following are some of the basic frequently asked questions regarding toxicology and drug testing – and corresponding answers.

Why is drug testing performed?

There are several reasons to perform drug testing, the following is a short list of why a test may be performed

  • Check for drug use in the workplace. Testing is common for people who work in public safety, such as bus drivers or child care providers. Some jobs require a tox screen as part of the hiring process.
  • Check for drug use in students involved in extracurricular activities, such as sports and cheerleading.

What is Toxicology Testing?

“Toxicology” is an all-encompassing term related to the detection and effects of poisoning.  “Poisoning” occurs when used drug usage used illegally or in improper dosages, can be toxic to a body.

A toxicology test (“tox screen”) checks for drugs or other chemicals in your blood, urine, or saliva. Drugs can be swallowed, inhaled, injected, or absorbed through the skin.  In rare cases, a tox screen can check your stomach contents.

A tox screen may check for one certain drug or for up to 30 different drugs at once. These may include prescription medicines, nonprescription medicines (such as aspirin), vitamins, supplements, alcohol, and illegal drugs.

How long do traces of drugs stay in your system after use?

The answer depends on which drug; type of specimen; each person’s own metabolism; drug concentration and/or dosage; how often the drug was used; and the sensitivity of the testing procedure. The following tend to be the range:

  • Blood testing is least reliable.  Only detectable 5-48 hours after usage.
  • Body fluids will retain drugs for up to two days.
  • Urine will retain traces of drug use for 4-7 days, however, it only indicates usage, not level of impairment.
  • Hair strand tests are effective as drug traces remain in the hair for up to 90 days. (Please note, it takes 10-14 days for drug traces to enter into the hair shaft).
  • Nail clipping tests will indicate signs of drug usage for up to six (6) months.

How long does it take to receive drug testing results?

Note that turnaround time begins upon receipt of the specimen at the laboratory. The average turnaround times for our most commonly ordered tests are as follows:

  • Blood and urine samples with negative testing results take 24 hours.
  • Hair, nail and oral fluid negative testing results take 24-48 hours.
  • Positive testing results take up to 72 hours.
  • Unknown substance analysis takes up to 10 business days.
