Abstract

A method and apparatus for determining a coagulation property of a sample of fluid, the method comprising causing oscillation of at least one magnet (10), wherein said oscillation comprises: a first oscillation within a first frequency range for a first period of time; and a second oscillation within a second frequency range different to said first frequency range for a second period of time.
