Automated equipment to carry out complete blood counts was developed in the 1950s and 1960s. The cells that circulate in the bloodstream are generally divided into three types: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes).
Ethylene oxide (EtO) is produced in large volumes and is primarily used as an intermediate in the production of several industrial chemicals, the most notable of which is ethylene glycol.

This test helps manufacturers demonstrate the safety of products sterilized by EO by determining compliance with accepted residual limits.
