Details about Ketamine Screen (Urine)
What is the Ketamine Screen (Urine) test?
The Ketamine Screen (Urine) is a toxicology test that detects the presence of ketamine and its metabolites in a urine sample. Ketamine is a dissociative anaesthetic that may be used medically but is also misused recreationally.
Urine testing is the preferred method for ketamine screening because ketamine and its metabolites are excreted through the kidneys and can be detected for a period after use. This test identifies recent exposure, rather than long-term historical use.
The test is commonly used in clinical toxicology, substance misuse assessment, workplace screening, and medico-legal investigations.
Why do I need a Ketamine Screen (Urine) test?
Ketamine use may cause physical, psychological and urinary tract complications. Screening helps identify exposure when symptoms, behavioural concerns or compliance requirements exist.
You may need a Ketamine urine test if you:
- Have suspected recreational drug use
- Experience unexplained neurological or psychological symptoms
- Are undergoing substance misuse assessment
- Require workplace or occupational drug screening
- Need medico-legal or compliance testing
- Have urinary symptoms linked to ketamine misuse
- Require confirmation of recent exposure
Symptoms associated with ketamine use may include:
- Confusion or dissociation
- Memory impairment
- Hallucinations
- Agitation or anxiety
- Bladder pain or urinary frequency
- Nausea or vomiting

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
