Advantages of a new anticoagulant in routine hematology on the Coulter Counter S-Plus STKR analyzer.

The authors report the advantages of a new anticoagulant-antiaggregant mixture that avoids the deleterious effects of ethylenediaminotetraacetic acid (EDTA) on mean platelet volume and also prevents EDTA-induced platelet clumping. It is suitable for routine cell counting and sizing with the Coulter Counter S-Plus STKR. The values of the common hematologic parameters agree well with those from EDTA-treated samples and are stable for at least eight hours after sampling.
