Arsenic is very quickly removed from the body so generally it will not be detected after 2 days unless you have a very large amount.
It would be worth having another test done. If arsenic appears again then it could indicate you have exposure to arsenic every day - perhaps from water or food or some contamination (especially if you happen to be in taxidermy).
Do not try to treat the arsenic - it will be removed from the body rapidly - so do not chealators for this (these are used when someone has a very high does of arsenic and will likely die otherwise). If the arsenic persists you will know there is some continual exposure and you will need identify this (some preservatives, arsenic based paint, some treated timber, food, water, some termite controls etc...)
CHEALTON IS GOOD IF IT IS DONE IN IV FASHION, THERE IS ANOTHER WAY TO REMOVE ARESNIC, ITS CALLED DMPS, DONE BY SHOTS, A HEALTH CLINIC IN MB , SC called Aware Med. has this shot , it is done in a series of 3 ,6 or 9 mos or longer to remove the arsnic in the body,. You still need to be tested in each of the 3 mos intervals to see what your levels are; I am personally going thru this myself, the detox from this is not plesant and you need to be in reasonable good health to stand. But it is working for me so far...the shots are to be taken 1 per week in the series of months. good luck. You can take pill form GOOD QUALITY chealton for other heavy metals , but must stay on it for a few years to keep it out of your system, we are subjected to heavy metals in our daily lives. I personally stay on it continious now for going on 7 years.
I know it is an alternative method, does anyone know if it truly works?
