If you are concerned about kidney function you can purchase some home urine test strips that will check your protein output (you do not want ANY protein in your urine as this could indicate kidney problems). The test strips depending on which one you purchase can test liver function, sugar levels, if white and red blood cells are present, specific gravety, and much more.
Do not however rely on just a home test, your physician can do a more complete urine exam which would tell the entire story on your kidney function.

Benedict's reagent is not typically used to find proteins. It is commonly used to test for the presence of reducing sugars, such as glucose. To determine protein concentration, methods like the Bradford assay or the Lowry assay are more commonly used.
One can test for protein in a sample by using a method called the Biuret test. This test involves adding a reagent to the sample, which causes a color change if protein is present. The intensity of the color change can indicate the amount of protein in the sample.
To test starch: To test starch you take the food sample, and add iodine solution if the colour turns black this means starch is present. To test for protein: To test for protein, you take the food sample and add Biuret A and Biuret B and shake, if the colour turns lilac this means that protein is present.
A common chemical test for proteins is the Biuret test. This test involves adding a solution of copper sulfate and sodium hydroxide to the protein sample, resulting in a color change from blue to purple if proteins are present. The intensity of the purple color can provide an estimate of the protein concentration in the sample.
because it helps to recognize any protein present within food
Normal results for a Bence Jones protein test should show no detectable levels of Bence Jones protein in the urine, indicating a healthy kidney function and no abnormal protein excretion. If Bence Jones protein is present in the urine, further investigation may be needed to determine the underlying cause.

Two real life applications using protein testing (biuret Test) Inlcude: - Lab tecs testing for protein in urine samples. If protein is present in the sample this indicates there may be problems with the kidney or other organs You should google " Urine Protein Test " for a full answer - As well you could use this test to test for the presence of protein in the food you eat. Although many pre-packed foods already have this information it may come in handy. For more info on this test and how you could use it go on livestrong.ca or google " protein testing in food"

If you get a positive Mantoux test it means that you have purified protein derivative. This test is used to test for TB or Tuberculosis. If you get a positive test, further testing is required to see if you actually have Tuberculosis.
1. Add 5 cm3 dilute sodium hydroxide (caustic!) to a 1% solution of albumen (the white part of an egg)2. Then add 1% copper sulphate solution3. A purple colour appears and this indicates that protein is present.
Common lab tests used to test for the presence of protein include a serum protein electrophoresis (SPEP) test, a urine protein test, and a total protein test. These tests can help diagnose conditions such as kidney disease, liver disease, or protein deficiencies.
