4 Types of Pre-Employment Drug Screening
You just landed your dream job but you have one last hurdle to clear before you can celebrate your big achievement: the pre-employment drug test. This practice to protect employers from making the mistake of hiring individuals who are using illicit drugs can cause prospective employees a few sleepless nights. However, before losing precious shuteye become familiar with the types of tests so you know what to expect.
1. Urine Test conducted at a lab or on site
The most traditional type of drug test is conducted at a lab and uses the potential employee’s urine to screen for drugs and alcohol. In some cases, the urine test can be completed on site at one of the employer’s location – to save money and for convenience. Most commonly five panel drug tests are performed that screen for marijuana, PCP, cocaine, opiates and amphetamines. If an employer wants a more robust view of an individual’s drug usage an in-depth 10-panel test can be implemented. Since alcohol passes through the system very quickly, urine tests are more effective in detecting illegal drug use rather than alcohol.
A blood test is used primarily to check alcohol and drug levels at the time the test is completed – for recent consumption. It is not as reliable as urine tests for long term detection but is more effective in determining current levels of alcohol and drugs in the system.
3. Hair follicle testing
When an employer wants a complete long-term picture of a potential employee’s drug use a hair test may be in order. Testing hair has proven to be effective in detecting illicit drug use for months. Utilizing hair can detect many illegal drugs such as marijuana, amphetamines, cocaine, heroin and PCP. Although the efficacy of testing hair is not in doubt when it comes to drugs, this test cannot be used to determine alcohol use.
Quick, easy and offering deeper insights, some employers may choose to perform a saliva test. Saliva testing is more effective in detecting specific drugs than urine but it has its drawbacks as well. Drugs and alcohol do not remain in saliva as long as they do in urine. Saliva testing is mainly used to check for recent usage and pinpointing a specific substance.
