Interlaboratory quality assurance program.

Abstract

The Coulter Interlaboratory Quality Assurance Program (IQAP) analyses data from several thousand haematology laboratories which use Coulter haematology controls (4C). Such peer group analyses are done at monthly intervals. These analyses compare the individual laboratory's performance with other laboratories using the same lot(s) of control cells on the same instruments. The data receipt and peer analysis methods are outlined using flow charts which describe the process.
