Get accurate rapid diagnostic results with our specialized Xylazine test strips designed for the detection of Xylazine in human urine. If your medical facility, treatment center, harm reduction program, or law enforcement agency requires fast reliable screening for this dangerous animal tranquilizer, these urine test strips are essential.
Our Xylazine test strips detect Xylazine commonly known as tranq or tranq dope at cut-off levels ranging from 100 to 1000 ng/ml depending on the specific assay configuration. You can detect Xylazine use in urine from 24 hours up to several days after consumption depending on dosage frequency and individual metabolism.
Xylazine is a non-opioid veterinary sedative increasingly found as an adulterant in illicit fentanyl, heroin, and cocaine supplies, making specialized testing critical for overdose prevention and public health surveillance.
What is Xylazine and Why Testing is Critical
Xylazine scientifically known as N-(2,6-dimethylphenyl)-5,6-dihydro-4H-1,3-thiazin-2-amine is a non-opioid alpha-2 adrenergic agonist veterinarian sedative, analgesic, and muscle relaxant approved for use in animals such as horses, cattle, and other large mammals. It is not approved for human consumption by the U.S. Food and Drug Administration or any international regulatory body.
In recent years Xylazine has emerged as a dangerous adulterant in the unregulated drug supply particularly in combination with fentanyl, heroin, and cocaine. This combination creates what users call tranq dope or the zombie drug due to the extreme sedation and severe skin wounds it causes.
Xylazine is not an opioid and therefore does not respond to naloxone reversal, making detection and avoidance critical for preventing overdose deaths. The drug causes profound central nervous system depression, respiratory depression, bradycardia, hypotension, and severe necrotic skin ulcers that can lead to amputation even without injection. Testing for Xylazine using specialized Xylazine test strips is now essential for harm reduction programs, treatment centers, and emergency medical services.
Advanced Screening with Xylazine Strips (Tranq Detection)
Xylazine, commonly known as “Tranq,” is a potent non-opioid sedative increasingly found in the illicit drug supply. Our Xylazine strips are engineered to provide a critical layer of safety by identifying this adulterant. Unlike standard tests, our strips are calibrated to minimize false negatives and provide clear visual indicators for forensic and professional use.
Technical Specifications & Performance
-
Detection Cut-off: Optimized at 1,000 ng/mL to ensure high-sensitivity detection.
-
Rapid Results: Get clear visual confirmation in 5 minutes or less.
-
Broad Detection Range: Identifies Xylazine in various forms, including powders and liquids.
-
Accuracy: 99% correlation with laboratory-grade screening methods.
-
Individually Wrapped: Each strip is sealed in a moisture-proof foil pouch for a 24-month shelf life.
The “Dilution” Factor
Many Xylazine strips fail due to the “Hook Effect” (too much substance causing a false negative). To ensure 99% accuracy:
-
Dilute: Mix a tiny amount of the sample with sterile water.
-
Dip: Submerge the Xylazine strips into the liquid for 15 seconds.
-
Read: Results are stable at 5 minutes. Note: A faint line still indicates a negative result.
How do you use Xylazine Test Strips?
Xylazine Test Strips are specifically designed for the detection of xylazine drug presence. These strips provide a reliable and efficient method for identifying the presence of xylazine, a commonly used veterinary sedative. With their high accuracy and ease of use, Xylazine Test Strips are an essential tool in drug screening and analysis.
Our drug testing kits for xylazine provide a reliable and efficient solution for detecting the presence of this substance. These test strips are designed with accuracy in mind, ensuring precise results in a timely manner. With their user-friendly nature and high sensitivity, our xylazine test strips are an indispensable tool for professional drug screening purposes.
How Xylazine Test Strips Work
Our Xylazine test strips utilize rapid lateral flow chromatographic immunoassay technology for the qualitative detection of Xylazine in human urine samples. The test principle relies on competitive binding where gold-labeled antibodies specific to Xylazine migrate up a nitrocellulose membrane via capillary action.
When Xylazine is present in the urine sample at concentrations exceeding the cut-off threshold it competes with the immobilized antigen for binding sites preventing the formation of a visible line in the test region. The control line always appears to validate proper test function. These Xylazine urine test strips detect the parent drug with high specificity and minimal cross-reactivity to other substances. The 100 to 1000 ng/ml cut-off level provides optimal sensitivity for clinical screening while minimizing false positives.
Results are available in just 5 minutes making these strips ideal for point-of-care testing in emergency departments, harm reduction sites, and clinical settings. The test requires no laboratory equipment, specialized training, or electricity, enabling deployment in field conditions and resource-limited environments.

Frequently Asked Questions
What is the cut-off level for these Xylazine strips?
Our Xylazine strips feature a 1,000 ng/mL cut-off level, which is the gold standard for detecting Xylazine (Tranq) in forensic samples while maintaining high sensitivity.
Can Xylazine strips detect Fentanyl?
No, these strips are specific to Xylazine. For comprehensive screening, we recommend using these alongside our 13-panel cups or Fentanyl-specific strips to ensure all adulterants are identified.
Why is my Xylazine strip showing a faint line?
In drug testing, any line in the Test (T) region—no matter how faint—is considered a negative result. A positive result is only indicated by the complete absence of a line in the Test region.
Does naloxone reverse Xylazine overdose?
No, Xylazine is not an opioid and does not respond to naloxone. However, naloxone should still be administered for suspected opioid co-involvement. Xylazine overdose requires supportive care including airway management and blood pressure support.
What are the signs of Xylazine use?
Signs include extreme sedation, difficulty breathing, slow heart rate, low blood pressure, and severe skin wounds or ulcers. Xylazine is often called tranq or the zombie drug due to its profound sedative effects.
