I would not be surprised that if you take a random healthy person from the street and perform a similar test, that it will look similar if not worse than your results on the toxins.
Mercury can be coming from dental fillings, but also fish.
Uranium can also come from tap water. If you want to check levels in your area, you can check out the great site:

The thing that stood out was the low levels of key trace minerals. Do you have enough high quality, trace mineral rich, salt in your diet? When you start eating and drinking more healthily, it is easy to go low in high quality salt, as anything processed and packaged contains quite a bit of cheap, bleached salt. Perhaps look into some trace mineral supplements or food that are high in the ones that looked low.
