Abstract
Whole blood surface tension of 15 healthy subjects recorded by the ring method was investigated in the temperature range from 20 to 40 oC. The surface tension σ as a function of temperature t (oC) is described by an equation of linear regression as σ(t) = (-0.473 t + 70.105) x 10-3 N/m.
Blood serum surface tension in the range from 20 to 40 oC is described by linear regression equation σ(t) = (-0.368 t + 66.072) x 10-3 N/m and linear regression function of blood sediment surface tension is σ(t) = (0.423 t + 67.223) x10-3 N/m.
