Which brings me to a new question..... ;)
NPN - Nitrogen, causing acidic conditions.... is this the last stage (chemical residue) of protein-digestion?

Well Here is what I came up with after a fairly short search on this question and as the note below claims it appears to be so! As NPN levels can be found in the blood after
being drawn from the digestive tract! I am not sure if I understand this correctly but Im sure ML will let us know if this is or is not correct and need for further research is necessary!


Non-Protein Nitrogen on Blood (NPN)

Non-protein nitrogen is a term applied to the nitrogen remaining after all the proteins have been precipitated out of the blood. The N.P.N. substances in the blood are urea, uric acid, ammonia, creatin, creatinin, sugar, chlorides in the form of sodium chloride and cholesterol. The normal N.P.N. is from 25-30 mg. per 200 cc blood. Many figures have been given by various workers for its determinations, as well as upon the state of digestion at the time the blood is drawn for examination. It has been clearly demonstrated that the N.P.N. of the blood rises and sinks like the tide, with reference to absorption from the digestive tract. This rise is, of course, not a very great one, about 4 mg. per 100 cc of blood, but it is sufficient to necessitate a variable figure for the normal value of N.P.N.

As the kidney is the great regulator of the composition of the blood, maintaining a practically constant level of the N.P.N., it is in disorder of this organ, especially, that most is to be expected from a study of the variations in non-protein nitrogen of the blood. Numerous workers have shown that, in the majority of cases, the N.P.N. increases with an increasingly severe nephritis. In cases tending toward uremia, or showing actual uremia, the values of N.P.N. are markedly increased, reaching in some cases as high as 350 mg. or over for 100 cc of blood. This rarely is seen in conditions other than uremia, so that this factor assumes great importance in diagnosis.
