Details about Toluene (Urine)
What is the Toluene (Urine) test?
The Toluene (Urine) test measures metabolites of toluene in urine to evaluate recent exposure to this volatile organic solvent. Toluene is widely used in industrial processes, fuels, paints, adhesives, and cleaning agents.
After exposure, toluene is rapidly metabolised in the body and excreted in urine, primarily as hippuric acid. Urine testing therefore provides a useful indication of recent or ongoing exposure rather than long-term accumulation.
This test is commonly used in occupational health, environmental exposure assessment, and toxicology investigations.
Why do I need a Toluene urine test?
Toluene exposure can cause acute and chronic health effects, often with non-specific symptoms that may be overlooked. Identifying exposure helps explain symptoms and guide risk reduction.
You may need this test if you experience:
- Headaches or dizziness
- Fatigue or weakness
- Nausea or gastrointestinal discomfort
- Difficulty concentrating or brain fog
- Irritation of eyes, nose, or throat
- Neurological symptoms with unclear cause
- Occupational exposure to solvents or fuels
- Suspected environmental or indoor air exposure
Testing helps confirm whether toluene exposure may be contributing to symptoms.
Benefits of the test
- Detects solvent exposure
Identifies recent exposure to toluene. - Useful for occupational health
Commonly used in workplace exposure assessments. - Supports investigation of vague symptoms
Helps explain neurological or systemic complaints. - Non-invasive urine testing
No blood draw required. - Objective exposure measurement
Provides measurable biomarker data. - Assesses recent exposure
Reflects short-term or ongoing contact. - Complements other toxicology tests
Often assessed alongside other solvents. - Supports environmental risk evaluation
Helps identify indoor or workplace exposure sources.
Step-by-step: How we offer testing
Clinic-based testing (UK-wide)
- Choose your nearest UK clinic
- Attend your appointment
- Provide a urine sample
- Sample sent to the laboratory
- Results are issued once analysis is complete
Home or hotel visit (+£60, UK-wide)
- Sample kit provided for home collection
- Urine sample collected at home or hotel
- Sample returned for laboratory analysis
Your results explained
Normal (no significant exposure)
- Toluene metabolite levels within reference range
- UK standard (typical): Hippuric acid <1.5 g/g creatinine
- Suggests no significant recent exposure
Elevated (possible exposure)
- Metabolite levels above reference range
- UK standard: ≥1.5 g/g creatinine
- Indicates recent or ongoing exposure
High (significant exposure)
- Markedly elevated metabolite levels
- UK standard: Significantly above 1.5 g/g creatinine
- Suggests substantial exposure with potential health impact
Reference ranges may vary by laboratory and occupational guidelines.

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.
