Will ketamine show on a workplace drug test in the UK?
Ketamine use has been rising across the UK in recent years, which means more people are asking an important question: will ketamine show up on a drug test?
The short answer is yes — but only if the drug test is designed to detect it.
In this guide, we’ll explain exactly how ketamine is detected, how long it stays in your system, and which drug tests will pick it up.
Does Ketamine show on a standard drug test?
Ketamine does not always show on standard drug tests.
Most basic drug screening kits (such as 5-panel tests) are designed to detect common substances like:
- Cannabis
- Cocaine
- Opiates
- Amphetamines
Ketamine is NOT usually included in many standard drug test panels used in UK workplaces.
To detect ketamine, you need a specific ketamine test or a multi-panel test that includes a test for ketamine (KET).
Which drug tests detect Ketamine?
Ketamine can be detected using the following types of tests:
1. Urine Drug Test (Most Common)
- Widely used in the UK
- Detects ketamine and its metabolites
- Often included in extended panel tests
- A urine drug test is the most reliable and commonly used method to detect Ketamine use
2. Saliva Drug Test
- Detects very recent ketamine use
- Less commonly used for ketamine specifically
- More popular for roadside or workplace testing
3. Blood Test
- Detects ketamine for a short period
- Typically used in medical or legal situations
4. Hair Drug Test
- Can detect ketamine for up to 90 days
Usually used in:
- Family court cases
- Child custody situations
- Legal investigations
How long does Ketamine stay in your system?
Detection times can vary depending on:
- Frequency of use
- Dosage
- Metabolism
- Overall health
Typical detection windows for Ketamine on a drug test:
- Urine: 2–4 days
- Saliva: Up to 24 hours
- Blood: Up to 24 hours
- Hair: Up to 90 days
Occasional users will usually clear ketamine faster than regular users.
Can you pass a drug test after taking Ketamine?
It depends on:
- The type of test used
- When the drug was taken
- Whether ketamine is included in the drug test panel
If the test does not include ketamine, it will not show up.
If it does include ketamine, it is likely to be detected within the timeframes above.
Do UK workplace drug tests check for Ketamine?
Most UK workplace drug testing programmes do not routinely test for ketamine unless there is a specific reason, although they are increasingly doing so on the recommendation of drug testing companies Like UK Drug Testing who are at the forefront of modern drug test membrane development.
However, ketamine may be included in:
- Expanded drug panels (common now in 7 panel drug tests and upwards)
- Random testing programmes
- Safety-critical industries
- Post-incident testing
Employers can choose which substances to include.
Can Ketamine cause a false positive on a drug test?
False positives for ketamine are rare, but like any drug test, they can happen.
If a workplace drug test result is positive for Ketamine:
- It should be confirmed using laboratory testing (GC/MS)
- This ensures accurate and legally defensible results
