Two methods for measuring current and what sense amplifier used are tackled in this app note from Texas Instruments. Link here (PDF)

Current is a signal that can provide valuable insight into how a system is operating. Under defined conditions, the amount of current required to perform a task is consistent, making the current information a useful indicator to determine if the system is operating within expectations. There are multiple measurement methods and locations where current is measured to evaluate this informative signal.
