Abstract
The present invention provides a method for preparing cells for use in a hematology blood control. The preparation steps, namely the use of cross-linking agents such as aldehydes, involve a step-wise process starting with very low concentrations of a cross-linking agent. Successive fixations involve an increase in the concentration of cross-linking agent.
