What is Gauss? Gauss is a unit of measurement used to describe both the coercivity of a magnet and its saturation magnetization. Basically, it describes how strong the magnetic fields are extending from the magnet and how strong of a magnetic field it would take to de-magnetize the magnet. The name comes from the mathematician physicist Carl Freidrich Gauss.
What is aHUS? In aHUS, the complement system (part of the immune system) is uncontrolled. Damage from the uncontrolled complement system is known as systemic thrombotic microangiopathy (TMA). If your complement system is uncontrolled, cells along blood vessel walls become damaged.
