[Determination of total nitrogen in biological milieux by chemoluminescence: a comparison with the reference method].
An assay technique for the chemiluminescent estimation of total nitrogen in biological samples have been used for two hundred urines and gastric fluids, and results compared with those given by the traditional Kjeldahl method. Chemiluminescence is accurate, reproducible, and appear to be well correlated with Kjeldahl assay technique. Without doubt, it is advantageous to the point of samples manipulation, that need no dangerous compounds, and by the way of her swiftness and her possible automation. Lastly, according with preliminary studies, this method seem as well practicable for solid samples as for liquid samples. This assay technique is therefore usefull in current practice to investigate nitrogen balance in every patient.
