FIELD: medicine.
SUBSTANCE: invention relates to field of medicine, namely to diagnostics. In sweat fluid, obtained as a result of performing physical exercise or heating body in sauna, heat cabin real (ε') and imaginary (ε") parts of complex dielectric permeability at frequency 0.3-1.2 GHz are measured many times. Mass concentration (S) is calculated by formulas: S=(ε'-a)/b·or S=(ε"-c)/d, where a, b, c, d are numerical coefficients for different body parts: left arm: a=81.0, b=18.0, c=4.1, d=1629, right arm: a=82.0, b=-63.7, c=3.2, d=1895, left leg: a=81.2, b=5.3, c=4.3, d=1618, right leg: a=81.1, b=-57.2, c=1.02, d=1963, face: a=81.4, b=-52.9, c=7.1, d=1459, chest and stomach: a=82.2, b=-142, c=8.4, d=2250. Orientation of time derivative trends ε'(τ) and ε"(τ) is determined. In case of 
orientation, functional state is estimated as state without pathology, in case of 
, 
, 
, 
orientation as state with present pathology.
EFFECT: method allows to carry out express diagnostics of diseases associated with water-salt disbalance.
