Useful studies as aids in medical procedures are based on one of four phenomena: the dilution of a known amount of isotope, to determine the volume of the diluting fluid; the rate of transfer from ...

Standard isotope-dilution mass spectroscopy-traceable methods for determining serum creatinine levels must be generally used in clinical laboratories. In young children, measurement and reporting ...

In particular, the combination of stable isotope dilution and an approach called multiple reaction monitoring (MRM) has shown great promise as a method to sensitively and reproducibly detect ...

FFM is composed of mainly water with some proteins and minerals. It is assumed that FM has no water and that is not the same as adipose tissue. Total body water can be measured by isotope dilution so ...
