Hey, all. I have successfully used my own frozen (clean) urine in the past to pass drug tests and recently submitted some again for another test. I filter it through a coffee filter and it looks purty as a picture. My question is, the sediment that collects at the bottom of the sample - does it need to be reconstituted into the rest of the urine before filtration so that parameters like specific gravity, pH and creatinine will be at normal levels, or can I just filter it without first shaking it to mix it? In the past, i believe I've just filtered it (it's been a while) without shaking. Just getting nervous about it this time for some reason. Any advice is appreciated.
