1. Product Overview
The DrugExam THC Advantage Multi-Level Marijuana Urine Test Kit is designed for the qualitative detection of THC metabolites in human urine at five distinct cutoff levels: 15 ng/mL, 20 ng/mL, 50 ng/mL, 200 ng/mL, and 300 ng/mL. This test provides an indication of the approximate concentration of THC metabolites, offering more detailed information than a simple positive or negative result.
The test is intended for in-vitro diagnostic use only. It is not intended for medical use or for screening purposes in employment settings unless specifically authorized.

2. Product Components
Each DrugExam THC Advantage Multi-Level Marijuana Urine Test Kit typically includes:
- Individually sealed test devices (3 per pack).
- Detailed instruction manual.
Each sealed test device contains 5 individual test strips, each corresponding to a specific THC cutoff level.

3. Preparation for Testing
- Read the entire instruction manual carefully before beginning the test.
- Ensure the test device and urine sample are at room temperature (15-30°C or 59-86°F) before testing.
- Collect a urine sample in a clean, dry container.
- Open the foil pouch and remove the test device. Use the test as soon as possible after opening the pouch.
4. Operating Instructions
Follow these steps to perform the DrugExam THC Advantage test:
- Remove the cap from the test device.
- Immerse the absorbent tips of the test device into the urine sample. Ensure the urine level does not exceed the MAX line printed on the device.
- Hold the device in the urine for approximately 10-15 seconds.
- Remove the device from the urine and replace the cap.
- Place the test device on a clean, flat, non-absorbent surface.
- Wait for the colored lines to appear. Read results at 5 minutes. Do not interpret results after 10 minutes.

5. Interpreting Results
Each test strip on the device has a Control line (C) and a Test line (T). The presence or absence of these lines determines the result for each specific THC cutoff level.
5.1. Negative Result (No THC Detected at Specific Level)
Two colored lines appear: one colored line in the control region (C) and another colored line in the test region (T). A negative result indicates that the THC metabolite concentration in the urine sample is below the detectable cutoff level for that specific strip. Note: The intensity of the T line may vary; any faint line in the T region should be considered a negative result.
5.2. Presumptive Positive Result (THC Detected at Specific Level)
One colored line appears in the control region (C), and no colored line appears in the test region (T). A presumptive positive result indicates that the THC metabolite concentration in the urine sample is at or above the detectable cutoff level for that specific strip.
5.3. Invalid Result
No colored line appears in the control region (C), or a control line appears without any test lines. An invalid result indicates insufficient specimen volume or incorrect procedural techniques. Review the instructions and repeat the test with a new device.
5.4. Multi-Level Interpretation
The DrugExam THC Advantage test provides results for five distinct levels:
- Level 1: THC 15 ng/mL (Ultra Low Detection)
- Level 2: THC 20 ng/mL (Low Detection)
- Level 3: THC 50 ng/mL (Standard SAMHSA Laboratory Level)
- Level 4: THC 200 ng/mL (High Detection)
- Level 5: THC 300 ng/mL (Extra High Detection)
By observing which test lines (T) are present or absent across the five strips, you can determine the approximate concentration range of THC metabolites in the sample. For example, if the 15 ng/mL strip shows a presumptive positive (no T line) but the 20 ng/mL strip shows a negative (T line present), the concentration is between 15 ng/mL and 20 ng/mL.

6. Troubleshooting
- No Control Line (C) Appears: This indicates an invalid result. The test may not have been performed correctly, or the device may be faulty. Discard the test and repeat with a new device, ensuring proper immersion and sufficient urine volume.
- Faint Test Line (T) Appears: Even a very faint test line should be interpreted as a negative result for that specific cutoff level. The intensity of the test line can vary due to factors such as the concentration of the analyte, the sensitivity of the antibody, and the specific batch of the test.
- Urine Absorbs Above MAX Line: If the absorbent pads are immersed too deeply, exceeding the MAX line, it can lead to inaccurate results or an invalid test. Ensure the urine level remains below the MAX line during immersion.
- Results After 10 Minutes: Do not interpret results after 10 minutes. The accuracy of the test may diminish over time, and faint lines may appear or disappear, leading to incorrect readings.
7. Storage and Handling
- Store the test kit in its original sealed pouch at room temperature (2-30°C or 36-86°F).
- Do not store in direct sunlight, moisture, or heat.
- Do not freeze the test kit.
- Do not use the test device after the expiration date printed on the foil pouch.
- Keep out of reach of children.
