Overview
Providers analyze your blood and urine for signs of M protein. They also evaluate other factors to establish the risk MGUS will become cancer or a more serious blood disorder. These risk factors include:
- The amount of M protein in your blood.
- The type of M protein in your blood.
- The amount of free light chains in your blood. Free light chains (FLC) are proteins made by plasma cells. FLC tests detect abnormal concentrations of free light chains.
Studies show that people who have all three risk factors have a 58% chance of developing blood cancer within 20 years. People who don’t have any risk factors have a 5% chance of developing blood cancer within 20 years.
