Abstract
The present invention discloses multi-purpose metering fluid/rinse reagents for use in automated cellular analyzers that use liquid volumetric metering. The compositions contain a chelating agent, an ionizing salt, optionally a stabilizing ion, a buffer, a non-hemolytic surfactant, and optionally an antimicrobial agent. Advantageously, the compositions produce less than one part-per-million of formaldehyde over the course of one year. Methods for using the compositions are also described.
