From Wikipedia, the free encyclopedia. In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate determining step (RDS) or rate-limiting step.
The sedimentation rate (sed rate) blood test measures how quickly red blood cells (erythrocytes) settle in a test tube in one hour.The more red cells that fall to the bottom of the test tube in one hour, the higher the sed rate.When inflammation is present in the body, certain proteins cause red blood cells to stick together and fall more quickly than normal to the bottom of the tube.he more red cells that fall to the bottom of the test tube in one hour, the higher the sed rate.
