FAQ

A faint second line still counts as a negative result.

Any visible line - no matter how faint - means the substance was not detected above the cut-off level.

Only a completely absent line counts as positive.

The cut-off level for our standard THC test is 50 ng/mL.

The 3-level test screens at 20, 50, and 100 ng/mL, giving a more detailed picture of THC concentration in the urine.

The cut-off level is the minimum concentration of THC metabolites that must be present in urine for the test to show a positive result.

If the amount in the sample is below the cut-off, the test shows negative - even if a small amount is present.

Detection times vary depending on frequency of use.

  • Occasional users may test positive for 3 to 7 days after last use.
  • Regular users may test positive for 2 to 4 weeks.
  • Heavy or daily users may test positive for up to 30 days or more.

Individual results also depend on metabolism, body fat percentage, and hydration levels.

Each package includes:

  • The test strip or dip card
  • A detailed instruction
  • Step-by-step guide

The exact quantity depends on the pack size ordered.

THC metabolites typically become detectable in urine within a few hours after first use - the test will not show positive immediately after consuming.

The test detects THC-COOH, the main metabolite your body produces after processing cannabis - regardless of how it was consumed. This includes smoking, vaping, edibles, oils, and tinctures.

Under normal everyday conditions, a positive result from secondhand smoke is extremely unlikely. You would need to be in an enclosed, heavily smoke-filled space for an extended period for secondhand exposure to potentially affect the result.

Pure CBD products with no THC content should not cause a positive result. However, some full-spectrum CBD products contain trace amounts of THC.

If you use full-spectrum CBD regularly or in high doses, there is a small risk of a positive result.

Certain medications may occasionally trigger a false positive, including:

  • Ibuprofen or naproxen at high doses,
  • Proton pump inhibitors such as omeprazole or pantoprazole,
  • Antiretroviral medications used in HIV treatment.

If you receive an unexpected positive result and are currently taking any prescription or over-the-counter medications, consult a healthcare professional and confirm the result with a certified laboratory.

Our tests are designed for personal at-home screening only. They are not DOT-certified or legally admissible for employment, court, or probation purposes. For any official use, results must be confirmed by a certified laboratory using GC-MS or LC-MS methods.

Water contains no drug metabolites, so the test correctly shows negative - it is not testing what substance is in the sample, only whether THC metabolites are present above the cut-off level.

An invalid result only occurs when the control line does not appear, which means the test did not function properly, not that the sample was too diluted or the wrong substance.

At-home tests are immunoassay screening tests that give a quick yes or no result based on whether a substance is above a set cut-off level.

Laboratory tests use more advanced methods such as GC-MS or LC-MS that can identify and measure exact substance levels with much higher accuracy.

A positive at-home result should always be confirmed by a certified lab before any serious decisions are made.

THC levels in urine can fluctuate throughout the day depending on hydration, physical activity, and time since last use. First morning urine typically shows higher concentrations. Drinking a lot of water before testing can dilute the sample and produce a negative result even when you might otherwise test positive.

Urine can be stored at room temperature for up to 8 hours, or refrigerated at 2 to 8 degrees Celsius for up to 48 hours.

Do not freeze.

Always bring a refrigerated sample back to room temperature before testing.

Yes, many people use our tests to track their THC detox progress. For the most consistent results, test with first morning urine at the same time each day and avoid excessive hydration before testing.

A positive screening result means THC was detected above the cut-off level. If the result is unexpected or needs to be confirmed, we recommend retesting for the next few days with the first-morning result. If still positive, submit a sample to a certified laboratory for confirmation testing before making any important decisions.

No. These are urine-based tests that detect THC metabolites produced by your body after consumption. They cannot be used to test substances directly such as vape juice, edibles, concentrates, or oils.

  • Store at room temperature between 2 and 30 degrees Celsius (36 to 86 degrees Fahrenheit), away from direct sunlight and moisture.
  • Do not freeze.
  • Keep in the original sealed packaging until ready to use.

Tests expire 2 years from the manufacturing date printed on the packaging.

Always check the expiration date before use - an expired test may give inaccurate results.

A faint second line still counts as a negative result. Any visible line - no matter how faint - means nicotine or cotinine was not detected above the cut-off level.

Only a completely absent line counts as positive.

The cut-off level for our nicotine test is 200 ng/mL of cotinine, which is the main metabolite your body produces after processing nicotine.

The cut-off level is the minimum concentration of cotinine that must be present in urine for the test to show a positive result.

If the amount in the sample is below the cut-off, the test shows negative - even if a small amount is present.

This test detects cotinine, the metabolite your body produces after processing nicotine - not nicotine itself.

Cotinine typically becomes detectable in urine within 2 to 4 hours after use, so the test will not show positive immediately.

Once detectable, cotinine remains in urine:

  • For 3 to 4 days in occasional users
  • Up to 7 days or longer in regular or heavy users

Individual results also depend on metabolism, frequency of use, and hydration levels.

Each package includes:

  • The test strip
  • A detailed instruction leaflet
  • Step-by-step guide

The exact quantity depends on the pack size ordered.

In typical everyday exposure to secondhand smoke, a positive result is unlikely. However, heavy or prolonged exposure in an enclosed space may result in cotinine levels high enough to trigger a positive result. This is relatively uncommon under normal conditions.

Urine can be stored:

  • At room temperature for up to 8 hours
  • Refrigerated at 2 to 8 degrees Celsius for up to 48 hours.
  • Do not freeze.
  • Always bring a refrigerated sample back to room temperature before testing.
  • Store at room temperature between 2 and 30 degrees Celsius (36 to 86 degrees Fahrenheit), away from direct sunlight and moisture.
  • Do not freeze.
  • Keep in the original sealed packaging until ready to use.

A faint line on any panel still counts as a negative result for that substance.

Any visible line - no matter how faint - means the substance was not detected above the cut-off level for that panel.

Only a completely absent line on a panel counts as positive for that substance.

We offer two 5-panel tests that differ by one substance.

The standard 5-panel screens for:

  • Marijuana (THC)
  • Cocaine (COC)
  • Amphetamines (AMP)

This test detects the presence of fentanyl and many of its analogues in a substance sample.

It is designed as a harm reduction tool to help identify whether fentanyl has been added to or is present in a substance, which can be an unknown and life-threatening risk.

  • A small amount of the substance being tested is dissolved in water.
  • The test strip is then dipped into the solution.
  • The result indicates whether fentanyl or its analogues are present above the detection threshold.

The test does not measure quantity - only presence or absence.

The cut-off level for this test is 20 ng/mL, which is a very sensitive threshold designed to minimize the risk of a false negative.

The specific detection details are also listed in the instruction leaflet included with the test.

Each package includes:

  • The fentanyl test strips
  • Sample collection container
  • Pipette
  • Laboratory spoon
  • A detailed instruction leaflet
  • Step-by-step instructions

The exact quantity depends on the pack size ordered.

The test can be used to test powder substances, or pills dissolved in water.

Always follow the preparation instructions in the leaflet carefully, as the water-to-substance ratio matters for accurate results.

One line means fentanyl was detected above the threshold.

Two lines means fentanyl was not detected above the threshold.

Always refer to the instruction leaflet to confirm correct interpretation before reading your result.

The test may not detect all fentanyl analogues equally, and results depend on the concentration present and correct test preparation.

  • Store at room temperature between 2 and 30 degrees Celsius (36 to 86 degrees Fahrenheit), away from direct sunlight and moisture.
  • Do not freeze.
  • Keep in the original sealed packaging until ready to use.

This test measures the pH level of vaginal discharge to help identify potential imbalances.

  • A normal vaginal pH is between 3.8 and 4.5.
  • A higher pH may indicate bacterial vaginosis or trichomoniasis
  • A lower pH may be associated with a yeast infection.

This test is a screening tool only and is not a diagnosis.

Each package includes:

  • The pH test device
  • A detailed instruction
  • A color reference chart for interpreting results

The exact quantity depends on the pack size ordered.

The test should not be used during menstruation as blood can affect the pH reading and give an inaccurate result.

It should also not be used within 48 hours of sexual intercourse, after using vaginal creams, gels, or lubricants, or after douching, as these can all temporarily alter vaginal pH.

Compare the color of the test device to the color reference chart included in the instruction leaflet.

Always read the result within the time stated in the instructions.

This test is a screening tool only and cannot diagnose a condition. If your result shows an abnormal pH, or if you are experiencing symptoms such as unusual discharge, odor, itching, or discomfort, we recommend consulting a healthcare professional for proper diagnosis and treatment. Do not self-treat based on this test result alone.

  • Store at room temperature between 2 and 30 degrees Celsius (36 to 86 degrees Fahrenheit), away from direct sunlight and moisture.
  • Do not freeze.
  • Keep in the original sealed packaging until ready to use.

Tests expire 2 years from the manufacturing date printed on the packaging.

Always check the expiration date before use - an expired test may give inaccurate results.

This test detects the presence of E. coli and coliform bacteria in water, which are indicators of fecal contamination.

Their presence suggests the water may be unsafe for drinking or other household use and should be treated or avoided.

You can test tap water, well water, spring water, pond water, lake water, rainwater, and any other water source you want to assess for bacterial safety. The test is suitable for home, garden, and recreational water sources.

Fill the test bottle with the water sample to the marked line, close the cap securely, and shake gently to mix. Place the bottle in a warm location at around 35 to 37 degrees Celsius, or as specified in the instruction leaflet.

Wait for the required incubation time before reading the result.

A color change indicates the presence of bacteria.

Always follow the exact steps in the instruction leaflet included with your test.

The test requires an incubation period of 24 to 48 hours before results can be read. Do not read results before the minimum incubation time has passed as the result may not be accurate. The exact timing is specified in the instruction leaflet included with your test.

  • Store at room temperature between 2 and 30 degrees Celsius (36 to 86 degrees Fahrenheit), away from direct sunlight and moisture.
  • Do not freeze.
  • Keep in the original sealed packaging until ready to use.
