uranium

Hi - i have had two hair mineral tests in the past year from doctors data and they showed elevated uranium. levels went from 0.16 to 0.2 ug/g. this has me very concerned since i have had no exposure to radioative materials and drink mountain spring bottled water 90% of the time. My doctor wants to perform a urine test with and without DMSA challenge but i am afraid to take such a high dose of DMSA for the test since i may have impaired renal clearance issues. Any idea how i can detrmine if i in fact do have uranium poisoning and if so what can i do to get it out of my body? thanks so much Tweet
