           | " If you buy the same product twice, how much will chemical
           | levels vary?
           | 
           | When we bought two samples of the same product, plastic
           | chemical levels differed on average by 59%, calculated as
           | Relative Percent Difference (RPD).
           | 
           | To test whether completely identical samples would show
           | different levels of chemicals, we sent about 10% of our
           | products in triplicate. This means we sent three copies of
           | the product from the same batch - with matching lot number
           | and expiration date - bought at the same store on the same
           | day. We found that the triplicate samples differed less - on
           | average by 33%.
           | 
           | Our lab's quality control methodology lists 20% RPD as an
           | acceptable margin of measurement error for duplicate samples,
           | meaning if you tested the exact same sample twice, you could
           | see up to a 20% difference purely due to measurement noise.
           | Taking that into account, the RPD for two samples of the same
           | product (not necessarily from the same lot) ranges from
           | 39-59%. For samples with the same lot number and expiration
           | date, the RPD narrows to 13-33%.
           |

         | I love this idea. I hope to see this type of testing for
         | everyday food as well. Here are some hurtles you might run
         | across
         | 
         | * Can you source low plastic baby food, or low plastic food to
         | process into baby food? Seems like large quantities of the food
         | supply are contaminated.
         | 
         | * How can you comparatively advertise your low test results
         | compared to the competition without being the victim of
         | lawsuits? Lawsuits from established companies feels inevitable,
         | but being involved in a lawsuit can harm funding rounds for
         | startups, even if it's baseless.
         | 
         | * Would brick & motor stores want to deal with you if you are
         | essentially calling the rest of their products poison?
         | 
         | * Will you need special tools for processing the food that
         | introduces minimal plastics?
