Yes they did test BUT they ignored the patient had an allergy to iodine and was on a drug known to interact with iodine and damage the kidneys. The damage is permanent. Immediately after the test he collapsed and was rushed to the ER and put on saline IV drip but it was too late to reverse the damage. It is bad enough having diabetes and being supper careful to then have medical personnel blow it big time. Now we manage that and have been successful to prevent any further deterioration over these many years.
