Just follow the specific steps to heat it up and see if it appears cloudy, precipitate, etc. In addition, to see if it is false, add some vinegar for further testing. 3, test paper method: there is a test paper is specially tested this, in the medical store can be bought. Put the test paper into the urine, according to the color shown and the standard card for comparison can determine their own urine in the end there is no protein, very simple and very convenient.
