How does a Urine Laboratory Drug Test work?

After taking a drug, it enters a person’s bloodstream. Next, the drug transfers from the liver to the bladder. As a result, what remains of the drug is excreted out of the body through urine.

First, we perform a screen of the sample in the lab. The screen is very accurate. As a result, it provides an advantage over the urine instant Point of Care (POC) Drug Test. The screen takes 1 to 2 working days from the appointment. If the lab detects nothing in the screen, we will issue a negative (Pass) report. But if the sample screens non-negative, the sample will go on for further testing. In this case, we will issue an ‘Undergoing Further Analysis’ notification.


Laboratory Confirmation Drug Testing

This will identify the drug or metabolite found in the sample. Also, it will determine the quantity of the drug present. This process can take up to a further 3 working days.

Next, if the presence of the drug is over a specific cut-off level (see below), we will issue a positive lab report. This could provide evidence of abuse.

In this case, the report may specify whether the drug and its quantity are therapeutic. For instance, in line with declared medication. To confirm this, we also offer an optional Medical Review Service.

We can include many different drug groups in the analysis. These include:

  • Ethanol*
  • Amphetamines, including Methamphetamine and Ecstasy (MDMA)
  • Barbiturates
  • Benzodiazepine, including Diazepam and Temazepam
  • Cannabis
  • Cocaine
  • Methadone
  • Opiates
  • Buprenorphine
  • Ketamine
  • LSD
  • Methaqualone
  • Phencyclidine
  • Propoxyphene

* The urine test can show the level of alcohol in a person’s body. But they are more likely to request a breath alcohol or blood alcohol test if available.


Cut-off levels

Urine drug tests use cut-off levels. This means that a result will only be positive if the amount of the drug is above a certain level. Cut-off levels follow EWDTS guidelines. Having cut-off levels helps prevent false-positive results. Also, they reduce the chance of testing positive after only passive exposure to a drug.


Urine Laboratory Drug Test Detection

Many factors affect the length of time that this test can detect a certain drug in the body. These factors include:

  • body mass
  • hydration levels
  • the acidity of the urine
  • how long ago the person took the drug

Also, other factors include gender, age and even genetics.

If a person uses a drug often or in large quantities, a urine test could detect the drug for a longer period.

For example, the detection times for cannabis can depend on how often a person uses it.

Below is an example of how long drugs can stay in the system for.

Other options are also available for certain circumstances such as spiking incidents. When you call us, a Clinical Advisor can provide details about this service.
