@bdade59 I have chronic kidney disease, with other health issues. There is a high amount of protein spillage from my kidneys. I combine a visual monitoring with other factors like general overall feeling, energy level, any pain locations to assist me in following my condition, not relying solely on lab tests. I follow a renal disease diet, and limit the amount of protein in the diet [still get a high spillage]. No cholesterol medication for me.

yes, I have seen that it is protein like egg whites and it is a sign that there is to much being dumped into the urine as waste instead of being used by the body like it should.

Eating too much protein is very rarely the issue. This is almost always dead/dying liver-formed protein. The protein is formed, mis-folds, forms another, and dies within a couple hours or so. It can then be deposited in any tissue in the body as prions, or be deposited in any liquid waste. If your body is excreting more than a half-gram of protein in 24 hours, you are moving into dangerous territory. The Bindings Site Serum Free Lite Chain assay, coupled with the 24-hour urinary protein measurement, should give very good analysis. But you must be careful. There are too many scrap-paper labs out there, mostly owned by doctors, which do not have the rights or the equipment to do the sFLC or the 24-hour, so they fake up something else, and say "Oh, it's OK. This person is going to die anyway." ALWAYS be sure the lab is licensed. I use ARUP in Salt Lake City, mostly, but there others with great records, such as Boston, Emory, Duke, MD Anderson.

@bdade59. About the foamy urine and protein. This foam is LIVER produced protein which has died and begun the decay process, not dietary as from eating too much protein. The kidneys then do not extract the dead protein as they should. The foam on the urine is easy to note. Mine is almost always at least 1 cm (1/2 inch) thick on the toilet water, and sometimes up to 3 cm. If you can watch carefully, and perhaps catch the urine in a clear container you will see that the urine may have a very fine foamy texture. I record the general depth of the foam each morning. It is a mark of some Amyloidosis Light Chain difficulty, and should never be ignored. It is rarely dehydration or full bladder. https://www.OncLive.com says the Amyloidosis Serum Free Light Chain (sFLC), coupled with the 24 hour urine collection will give a very good reading on the state of our liver and kidneys. The sFLC is very accurate at the protein output at this level. The older tests are good only at much higher levels. The acceptable level of daily hepatic protein output is UNDER (<) 0.5 grams. Above that level reside many diseases. But do not use any lab or test not extremely accurate at the lower levels. oldkarl
