NTZ Single-Use Urine Test Strips | Isotonitazene Screening
The NTZ Single-Use Urine Drug Test Strip is a rapid qualitative screening device designed for the presumptive detection of Isotonitazene (NTZ). It uses a competitive immunoassay with visual line interpretation and is intended for professional in vitro diagnostic use. The individually packaged strip provides a convenient format for organizations and professionals performing screening according to established testing procedures.
Key Features
- Designed for Isotonitazene (NTZ) screening
- 1,000 ng/mL cutoff concentration
- Competitive immunoassay technology
- Simple dip-and-read format
- 5-minute result read time
- Clear visual line interpretation
- Individually packaged for single use
- Internal procedural control
How the NTZ Test Works
The NTZ test strip uses a competitive immunoassay to screen for Isotonitazene. The specimen moves through the test membrane, where the target analyte interacts with the test's antibody and drug-conjugate system. Results are determined by the presence or absence of a colored line in the test region.
A control line confirms that the test has been performed properly and that the specimen has moved through the test strip as intended.
Understanding the Results
- Negative: Two lines appear — one in the control (C) region and one in the test (T) region.
- Positive: One line appears in the control (C) region, and no line appears in the test (T) region.
- Invalid: No control line appears, and the test should be repeated with a new strip.
Any visible line in the test region is considered negative according to the manufacturer's instructions.
What's Included
- Individually packaged NTZ test strips
- Product inserts
Important Information
This test provides a preliminary screening result and does not determine the concentration of Isotonitazene in a specimen. A negative result does not completely rule out the presence of the target below the test's detection level. The manufacturer recommends confirmation with a more specific analytical method when a confirmed result is required.
For professional in vitro diagnostic use only. Always follow the manufacturer's instructions for use.
Important Notice: This device provides preliminary analytical results only. It is designed to detect the presence of fentanyl but does not measure purity, potency, or concentration. Confirmatory testing with specialized laboratory methods is recommended for final analysis. Intended for professional screening purposes. Single-use only. Do not use after the expiration date.
Frequently Asked Questions
Yes. These strips can be used to screen liquids, powders, and pills. For powders or pills, dissolve a small sample in clean water and mix thoroughly before testing. Follow the included instructions and read results within the recommended time window.
If the control line does not appear, the result is invalid and should not be interpreted. Discard the test and repeat the procedure using a new test strip. If the issue continues, discontinue use of the kit and contact the distributor.
Store the kit at 2–30°C until the expiration date shown on the sealed pouch. Keep the test sealed until use, protect it from direct sunlight, and do not freeze. Do not use a test if the pouch is damaged or if the expiration date has passed.
The manufacturer describes the test as a preliminary analytical screening test. When confirmation is required, a more specific analytical method should be used. The manufacturer identifies GC/MS as an established confirmatory method.
