Sensitive cannabis test 20 ng/ml – THC urine screening test

Sensitive cannabis test 20 ng/ml is a urine-based THC rapid test designed for sensitive screening of low THC levels. This sensitive cannabis test is suitable for situations where a more precise and clearly interpretable screening result is required compared to standard tests.

The product is a CE-marked in vitro diagnostic device (IVD). It is intended for professional use but, due to its ease of use, is also suitable for private individuals. No laboratory conditions or special equipment are required to perform the test.

What the test detects 🧪

The test detects THC’s primary metabolite, THC-COOH, in urine samples. THC is the main psychoactive substance found in cannabis, including marijuana and hashish.

• Cut-off value: THC 20 ng/ml

When is a sensitive cannabis test the right choice 🎯

The 20 ng/ml cut-off is intended for situations where more sensitive screening than usual is required. A sensitive cannabis test is commonly used for follow-up and post-monitoring, especially when low THC levels need to be identified.

• detects low THC concentrations
• more sensitive than standard 50 ng/ml cannabis tests
• suitable for follow-up and post-monitoring
• used in professional and controlled environments

The lower cut-off value may result in a longer detection window compared to tests with higher thresholds. Detection time is influenced by amount of use, frequency, and individual metabolism.

⏱️ Instructions for use and result interpretation

The test procedure is quick and straightforward.

• collect a urine sample in a clean and dry container
• immerse the test strip in the sample according to the instructions
• wait approximately 3–5 minutes and read the result

Results are interpreted using the two-line model.

• two lines indicate a negative result, no THC detected or concentration below 20 ng/ml
• one line indicates a positive result, THC detected above 20 ng/ml
• no control line indicates an invalid test and the test must be repeated

A faint test line is also interpreted as a negative result.

Detection window ⏳

Due to the low cut-off value, this sensitive cannabis test may detect THC residues in the body for a longer period than tests with higher cut-off values.

• detection may last for several weeks in some cases
• individual factors such as metabolism and usage history affect results

Package contents 📦

The package includes:

• individually packed sensitive cannabis test strip
• instructions for use

The following items are not included:

• clean and dry urine collection container

Typical areas of use 🏥

• social and healthcare services
• educational institutions and supervised units
• occupational health assessments
• transport and security sectors
• private individuals’ personal monitoring needs

Important information ℹ️

The very low cut-off value may, in some situations, react to significant passive exposure in enclosed spaces, for example if a person has stayed in the same room where cannabis has been smoked.

• this test is a qualitative screening test
• does not indicate time of use
• does not determine THC concentration or level of impairment

A positive screening result should be confirmed using a verification method.

Alternative with a higher cut-off 🔎

In situations where highly sensitive screening is not required, a test with a higher cut-off value may be more appropriate.

• the 50 ng/ml cannabis test is less sensitive
• does not usually react to passive exposure
• suitable for general screening and routine monitoring
