[Infographic] The 7 Sins of GMO Testing

With the use of GM crops increasing around the world, the challenges facing the analysis industry are many. Here are 7 common errors when testing GMOs in your laboratory.

The 7 Sins of GMO Testing

  1. Identifying the wrong target

    Know the events and proteins that comprise your target to avoid false positives and erroneous results.

  2. Choosing the wrong method

    DNA-based methods test for different targets than protein-based methods. Depending on the sample, they may deliver different results.

  3. Not understanding the different degrees of test sensitivity

    DNA-based methods are very sensitive and can detect a single copy of the target gene in the sample. Protein-based methods may require more test runs to guarantee a result.

  4. Removing impurities or treating the sample

    No washing, cleaning or heating the sample! If you do, you run the risk of removing traces of GM plants and ending up with inaccurate test results.

  5. Using an improper procedure to prepare your sample

    Proper cleaning of equipment avoids cross-contamination, and grinding samples to the right size ensures that lateral flow devices (LFDs) will work as expected. Even the shape of the extraction vessel is important.

  6. Customizing testing procedures

    Avoid this sin by reading and following the directions on the package insert. Ensuring your staff is trained in laboratory procedure can safeguard your testing process.

  7. Insufficiently cleaning your equipment

    Prevent cross-contamination by washing every component of your equipment – mill blades, jars, blenders – with liquid soap. Rinse them with water and handle all samples with gloves. Make sure your cleaning procedure is validated.
