Answer This Question

A:  Just hang it or stand it in an area but not a laundry room, or a bathroom and leave for 3 to 12 months to get an average reading.

    A:  You merely remove the caps on two small plastic canisters and place them 6" apart for 96 hours. The trick is to make sure you have shipping options that will reach ProLab within 24 hours of test completion.

    Issues with Prolab app and their website too.
    I completed the testing but can not register by the Prolab app or online website. The app does not accept Canadian Postal Codes and the website failed to recognize my entry in the "State" field. Also, the serial number is not clearly identified on the test kit. The form you mail back once the test is complete includes all of your personal information and full details of your credit card so this is a serious risk of fraud and identity theft if your return package is stolen. I would never buy a Prolab product again.
      Never got results
      Took money no results my husband died of cancer from radon

        Pro lab is a ripoff
        We bought this product , used it , sent it in for the test and all they did was cash my cheque and no test results , been over 1 year
          Not immediately
          I bought this product because I thought it would let me know the Radon level in my basement. It takes 3 to 12 months! I did not read the description close enough and have wasted my money. I already opened everything before I realized it was not the product I needed. Oh well. I need to know now, not a year from now.

            Testing is done in the US, not Canada
            Very disappointed to find that even though the tests are sent to a Canadian address, the lab is actually in the US. The accreditation details on Pro-labs website are for a US lab.

              Financial trap!!
              This is a scam. Once you read the fine print, you find that they want another $40.00 to process the test. When you send the test and your $40 bucks in: they go silent. They do manage to cash the check however. I've tried calling the company a few time and when they actually answer the phone - they are skilled at the run-around. Look else where for your tests.
