METHOD FOR TRIGLYCERIDES CONTENT DETERMINATION IN BLOOD SERUM BY DYNAMIC SURFACE TENSION RESULTS Russian patent published in 2018 - IPC G01N33/48 

FIELD: medicine.

SUBSTANCE: dynamic surface tension of a 1-3 ml blood serum sample is measured on a tensiometer operating by the principle of maximum pressure in the vial, the triglycerides content ([Triglycerides], mmol/l) is determined from the obtained dynamic surface tension values using the regression-correlation analysis formulas: [Triglycerides]=-0.11σ₁+0.14σ₂-0.1σ₃-0.09λ₁+5.79, where σ₁ [MN/m] is the surface tension at t=0.02 seconds, σ₂ [MN/m] is the surface tension at t=1 second, σ₃ [MN/m] is the surface tension at t=10 seconds, λ₁ [MN/m s^-1/2] is the angle of inclination of the final section of the curve in the coordinates σ/(t^-1/2).

EFFECT: improved accuracy.
