Will sea salt be a problem with the heavy metal test?

The Urine Test Collection Instructions (attached) state "avoid foods high in iodine (seafood, dairy, kelp) and selenium (Brazil nuts) up to 48 hours before collection."
According to the Redmond Real Salt webpage (https://kb.redmond.life/answers/real-salt-iodine), each 1/4 teaspoon of Real Salt contains roughly 18-23 micrograms of naturally-occurring iodine.
According to the USDA's Food Data Central database (https://fdc.nal.usda.gov/fdc-app.html#/food-details/746772/nutrients), 1 cup of milk has 36.2 micrograms of iodine.
For best results, follow the instructions as they are written.
