Spike recovery definition

Spike recovery means the fraction of analyte remaining at the point of final determination after it is added to a specified amount of matrix and subjected to the entire analytical procedure. Spike re- covery is typically expressed as a percentage. Spike recovery must be calculated for the method as written. For example, if the method pre- scribes using deuterated internal standards or matrix-matched calibra- tion standards, then the reported analyte recoveries must be calcula- ted according to those procedures.
