A faint test line does not mean more or less lead in your water. Our test is designed to read yes or no.

Test Line Visible - No lead

No Test Line Visible - Lead

Reminder: This is the opposite of a covid test. Two lines on Detekt lead test = good news.

Two test lines mean that no lead was found in your water sample. Should you experience this, please reach out for assistance.

If there is no control line after the 15 mins of testing, that is an invalid result. Should you experience this, please reach out for assistance.

This kit is designed as a screening tool to check tap or well water for the possible presence of lead. Results are visual and approximate. For official confirmation, use a certified laboratory.

Step 1: Collect Water Sample

• Use a clean cup or container to collect cold tap or well water.
  
• Avoid using hot water as it may not give an accurate result.
  

Step 2: Prepare the Test Cassette

• Remove the cassette from its package and place it on a flat, clean surface.
  

Step 3: Apply the Sample

• Follow the kit instructions to add the correct number of water drops (2) into the sample well.
  
• Be careful not to overfill.
  

Step 4: Wait for Development

• Allow the cassette to sit undisturbed for the recommended time, usually about 5 minutes.
  

Step 5: Read the Result

• Compare the test line to the guide below.
  

Tips for Reliable Screening

• If possible, collect water after it has been standing in pipes for several hours, such as first thing in the morning.
  
• For best insight, test water from more than one faucet.
  
• Always use fresh water samples for each test.
  

Important Note

This cassette provides a quick screening result only. Laboratory testing is recommended for detailed, quantitative results or if required for compliance.

No, our tests are designed to be read only within the specified time window listed in the instructions. Growth that appears after this window is not considered a valid result and often reflects normal environmental organisms that settle over time. Reading results after the recommended time can lead to false concern and misinterpretation.

In most cases, routine cleaning and normal maintenance are sufficient. If you have ongoing concerns, you may choose to retest after cleaning or consult a qualified environmental or health professional.
