Systems and methods to analyze blood or other fluid sample, such as performing blood clot testing. The systems and methods utilize bidirectional magnetic forces to push or pull a magnetic washer (46)along a post (48) in a chamber (32) housing the fluid sample both before and after clot initiation has been implicated. The magnetic washer (46) can be threadably connected to the post (48). In otherembodiments, the chamber (32) is configured such that the magnetic washer (46) does not rotate but only slides along the post (48). Once a clot (C) has been detected, the washer (46) can be moved either up or down to apply either compressive force or strain within the clot (C), as desired, to evaluate elastic properties or firmness of the clot (C). 分析血液或其它液体样本的系统和方法，比如执行血液凝块测试。该系统和方法在凝块形成之前和之后采用双向磁力来沿着接纳流体样本的腔室(32)中的柱(48)推动或拉动磁性垫圈(46)。磁性垫圈(46)可螺纹连接于柱(48)。在其它实施例中，腔室(32)构造成使得磁性垫圈(46)不旋转，而仅沿着柱(48)滑动。一旦检测到凝块(C)，就可根据期望使垫圈(46)向上或向下运动，以在凝块(C)内施加压缩力或应变，从而评估凝块(C)的弹性或牢固性。
