Types of Drug Testing Methods Available

Our testing centers provide many types of drug testing methods, below is a brief description of each method choose the one that is right for your need.


Drug Collector Training 300x200

Urine Test - Urine - Accredited Drug Testing provides drug testing utilizing the Urine screening method. Urine drug testing can be screened for 5, 7, 9, 10, 12 and 15 panel screenings. Urine drug tests can also include an expanded opiates analysis. Same day service is available and testing centers are located in all cities and in most cases within minutes from your home or office. The detection period for a urine drug test is up to 3-5 days and results are reported in most cases in 2- 3 days.

The procedure for a urine drug test is simple. A donor provides a urine specimen in a cup to a drug testing collection specialist who will then seal the specimen cup, complete various documentation including a chain of custody form, have the donor initial the specimen cup seal, provide identification and upon completion of the collection and paperwork the specimen will be sent in a secure manner by Currier to the laboratory for testing.


Hair Drug Testing - Accredited Drug Testing can provide a drug test utilizing the Hair follicle drug test method and a Hair drug test can be tested for 5, 10, and 12 panel screenings. The detection period for a hair drug test is up to 90 days and results are reported in most cases in 3 -5 days.

The hair drug test is becoming more frequently used by employers, courts and other government agencies due to the fact that the window of detection for illegal drug use for a hair is up to 90 days. Many courts have begun accepting hair testing in place of urine or blood testing and hair testing has been determined to be legally and scientifically admissible evidence in a court of law.

A hair drug test is a simple process whereby a drug testing collection specialist cuts approximately 120 strands of hair from the head or a specific amount from the body and submits the hair to a certified laboratory for analysis. A hair follicle drug test can be screened for a 5 panel, 10 panel or 12 panel test and can also include expanded opiates. If a donor does not have 1 ½ inches of hair on their head, body hair can be utilized, however, if the donor is bald and has none or very little body hair, a hair drug test is not an available option, a urine or oral/saliva test should be utilized.

In addition to our standard drug test panels, opioid screening can be added to any drug test to determine the use and/or abuse of any prescription drugs.

The Opioid Overdose Crisis

Every day, more than 130 people in the United States die after overdosing on opioids. The misuse of and addiction to opioids—including prescription pain relievers, heroin, and synthetic opioids such as fentanyl—is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total "economic burden" of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.

  • Roughly 21 to 29 percent of patients prescribed opioids for chronic pain misuse them.
  • Between 8 and 12 percent develop an opioid use disorder.
  • An estimated 4 to 6 percent who misuse prescription opioids transition to heroin.
  • About 80 percent of people who use heroin first misused prescription opioids.
  • Opioid overdoses increased 30 percent from July 2016 through September 2017 in 52 areas in 45 states.
  • The Midwestern region saw opioid overdoses increase 70 percent from July 2016 through September 2017.
  • Opioid overdoses in large cities increase by 54 percent in 16 states.

In the late 1990s, pharmaceutical companies reassured the medical community that patients would not become addicted to prescription opioid pain relievers, and healthcare providers began to prescribe them at greater rates. This subsequently led to widespread diversion and misuse of these medications before it became clear that these medications could indeed be highly addictive.3,4 Opioid overdose rates began to increase. In 2017, more than 47,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.1That same year, an estimated 1.7 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 652,000 suffered from a heroin use disorder (not mutually exclusive)
