Test Overview & Methodology
Trazodone therapeutic drug monitoring quantifies serum trazodone concentration to optimise dosing, confirm adherence, and prevent serotonin syndrome. The test is primarily ordered by psychiatrists when initiating therapy, after dose changes, or when adverse effects appear. The therapeutic window is typically 0.5–2.5 mg/L; levels above 2.5 mg/L may increase serotonin toxicity risk. Our laboratory uses LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry), which provides high specificity with no cross-reactivity and a quantification range of 0.5–2.5 mg/L.
| Feature | Our Test (ISO‑accredited) | Alternative Routine Lab |
|---|---|---|
| Detection Method | LC‑MS/MS (Gold Standard) | HPLC |
| Specificity | High, no cross‑reactivity | Moderate, possible interference |
| Quantification Range | 0.5–2.5 mg/L (therapeutic window) | Often semiquantitative |
| Batch Processing | Monthly cut‑off (sample by 7th) | Weekly or continuous |
| Turnaround Time | 2–3 weeks after monthly batch | 5–7 days |
| Regulatory Compliance | DHA & ISO 9001:2015 | May lack specific trazodone accreditation |
Physician Insight & Safety Protocols
“Trazodone levels should always be interpreted within the context of the patient’s complete clinical picture, including renal and hepatic function, co-administered medications, and psychiatric status. A single serum concentration can guide dose adjustments but does not substitute for ongoing clinical evaluation. If you experience new or worsening symptoms, contact your treating physician promptly.”

Patient FAQ & Clinical Guidance
1. What is the purpose of the Trazodone Therapeutic Drug Monitoring test?
This test measures the concentration of trazodone in your blood to help your doctor determine if your dose is within the therapeutic range (0.5–2.5 mg/L), confirm you are taking the medication as prescribed, and avoid toxicity such as serotonin syndrome. It is typically ordered when starting treatment, after dose adjustments, or if side effects appear.
2. How should I prepare for the Trazodone serum test?
No special preparation is required, but inform your doctor of all medications you are taking. A blood sample (2 mL in a red-top tube without gel separator) will be collected via our VIP Mobile Phlebotomy service at your home. The sample must be kept refrigerated and sent to the lab using our ISO-certified cold-chain logistics. The specimen must reach the lab by the 7th of the month for the monthly batch. Do not stop your medication unless instructed by your doctor.
3. When will I receive my Trazodone results?
Results are reported 2–3 weeks after the monthly batch cutoff (specimen must be received by the 7th of the month). This batch processing ensures rigorous quality control and cross-validation. You will receive a DHA-compliant report via our patient portal, and a DHA-licensed physician can provide telephonic interpretation if requested.
4. What if I miss the monthly cutoff date?
If your sample arrives after the 7th, it will be processed in the following month’s batch, and results will be delayed accordingly. Please schedule your home collection early in the month to avoid delays.
5. Is home phlebotomy available for this test?
Yes, VIP Mobile Phlebotomy with temperature-controlled cold-chain logistics is available daily from 8 AM to 11 PM. A trained phlebotomist will visit your home to collect the blood sample. This service is paid and can be arranged via WhatsApp at +971 54 548 8731.
