The Different Drug Abbreviations in Drug Testing

Drug testing is used by employers, organisations and individuals to screen samples such as urine, saliva, hair or blood for particular drugs or drug classes. While the full names of substances are sometimes used, drug tests and reports commonly use abbreviations.

These abbreviated drug names can be confusing if you are not familiar with them. This article explains some of the most common abbreviations you are likely to see on drug testing devices, reports and results.

Abbreviations provide a concise way of identifying the substances or drug classes included in a test. This is particularly useful on multi-panel devices, where several individual test strips may be contained within a relatively small cassette or cup.

Many drug test abbreviations are widely recognised, but the exact terminology can vary between test manufacturers and laboratories. Always check the instructions or report supplied with a particular test if you are unsure what an abbreviation represents.

Common Drug Test Abbreviations

Here are some of the abbreviations commonly used in drug testing and what they usually stand for:

• AMP – Amphetamine
• BAR – Barbiturates
• BZD / BZO – Benzodiazepines
• COC – Cocaine
• THC – Tetrahydrocannabinol, the main psychoactive component of cannabis
• MTD – Methadone
• MET – Methamphetamine
• MDMA – MDMA, commonly known as ecstasy
• MOP / MOR – Morphine
• OPI – Opiates
• OXY – Oxycodone
• PCP – Phencyclidine
• PPX – Propoxyphene
• TCA – Tricyclic antidepressants

Alcohol may be abbreviated as ALC on some testing devices or reports. Alcohol testing is often carried out alongside drug screening, particularly in workplace settings.

Buprenorphine is commonly abbreviated as BUP. It is an opioid medication that may be included on some multi-drug screening panels.

Ketamine is commonly abbreviated as KET. It is an anaesthetic medicine that is also used recreationally and may be included on certain drug testing panels.

The precise abbreviation shown on a test can differ between manufacturers. For example, benzodiazepines may appear as BZD or BZO, while morphine and opiate panels may use labels such as MOR, MOP or OPI depending on what the particular assay is designed to detect.

Drug Testing in Sports

Drug testing is also an important part of competitive sport. Testing programmes can screen athletes for prohibited substances and methods in accordance with the rules of the relevant sporting organisation.

Some abbreviations you may encounter in sports drug testing include:

• EPO – Erythropoietin, a hormone involved in red blood cell production
• hGH – Human growth hormone
• T/E ratio – Testosterone-to-epitestosterone ratio, which can form part of steroid profiling

The World Anti-Doping Agency (WADA) publishes the Prohibited List, which identifies substances and methods prohibited in sport. The list is reviewed annually, and the 2026 Prohibited List came into force on 1 January 2026.

Because sports testing operates under specific anti-doping rules, abbreviations used in this setting can differ from those found on routine workplace or home drug tests.

Urine Drug Test Panels

For urine drug testing, you will often see descriptions such as 5-panel, 10-panel or 18-panel. The number normally refers to how many drugs or drug classes the device is designed to screen for.

There is no single universal combination of substances for every 5-panel or 10-panel drug test. The drugs included depend on the particular device and manufacturer, so it is important to check the product specification rather than relying on the panel number alone.

For example, the Zoom Testing 5 Panel Drug Test currently screens for:

• Amphetamines (AMP)
• Cocaine (COC)
• Methamphetamine (MET)
• Morphine/opiates (MOR)
• Cannabis (THC)

The Zoom Testing 10 Panel Drug Screen – UK Workplace Standard currently screens for:

• Amphetamines (AMP)
• Barbiturates (BAR)
• Benzodiazepines (BZD)
• Cannabis (THC)
• Cocaine (COC)
• MDMA (Ecstasy)
• Methamphetamine (MET)
• Methadone (MTD)
• Opiates (OPI)
• Tricyclic antidepressants (TCA)

More extensive devices are also available. Some urine tests screen for 18 or more substances using a single sample.

Abbreviations for Opiate Sensitivity

Some urine drug tests identify different opiate screening cut-offs using labels such as OPI2000 or OPI300.

The number refers to the test’s stated screening cut-off in nanograms per millilitre (ng/mL). For example:

• OPI2000 – an opiate screening cut-off of 2,000 ng/mL
• OPI300 – an opiate screening cut-off of 300 ng/mL

A test with a lower cut-off can respond to a lower concentration of the substance or metabolite being screened for. However, the meaning of a particular abbreviation and cut-off should always be checked against the manufacturer’s instructions for that specific test.

Understanding Cut-Off Levels

Drug tests use defined cut-off levels for the substances or drug classes they screen for. These are commonly expressed in nanograms per millilitre (ng/mL) for urine testing.

The cut-off is the concentration used by the test to distinguish between a negative screening result and a result that indicates the possible presence of a drug or its metabolite. Different tests can use different cut-offs, so a figure such as 50 ng/mL should only be interpreted in relation to the drug and test to which it applies.

A screening result below the relevant cut-off is generally reported as negative for that drug or drug class. A result indicating drug levels at or above the screening cut-off should be treated as a preliminary or presumptive positive rather than definitive proof of drug use.

Where a positive result could lead to significant consequences, such as disciplinary or employment action, appropriate laboratory confirmation should be considered. Rapid screening tests are designed as an initial screen and should be used in accordance with the manufacturer’s instructions and the organisation’s testing policy.

Why Drug Test Abbreviations Matter

Understanding drug test abbreviations makes it easier to identify which substances a particular test is designed to screen for and to interpret the information shown on a device or report.

This is particularly important when comparing multi-panel tests. Two products described as a 5-panel or 10-panel test do not necessarily screen for exactly the same combination of drugs.

Although the terminology can initially seem complex, these abbreviations provide a concise way to identify the drugs or drug classes included in a test. When in doubt, always refer to the product instructions or laboratory report rather than assuming that an abbreviation has exactly the same meaning on every test.
