So I did the iodine loading test here in Spain. I simply ordered a 24 hour iodine urine test. I read the instructions carefully, didn't take any iodine for 2 days beforehand. I then started at 10 am, discarding the first urine of the day, took 50mg of ioderal, and peed in the bottle for 24 hours. Kept the container refrigerated, didn't eat any high iodine food or anything. To complete the test, I shook the bottle well, took a sample of about 50 ML and then shipped it to the lab refrigerated with dry ice.
Then my results came back and it said I had excreted 67.5mg. How is that possible? I have never heard of an excretion of >100% before nor read anything similar in the books. I contacted the lab and they said that its possible that you excrete whatever was in your body beforehand as well as the loading dose, but I think a mistake was made to be honest.
Any ideas? I am now on 12.5mg of iodine a day and I have noticed major upgrades in my health, so I am sure I am deficient. I rarely eat sea food and I didn't even have iodized salt the past few years so it makes total sense that I am.
