title: Low-molecular-weight heparin as a multipurpose anticoagulant for laboratory testing.
abstract: The availability of low-molecular-weight heparin (LMWH) for use as an anti-coagulant for laboratory testing was studied. Hematology and chemistry tests were performed with an automated hematology analyzer and an automated chemistry analyzer, respectively. The results of hematology tests of LMWH-treated blood were similar to those obtained for blood treated with ethylenediaminetetraacetic acid (EDTA)-2K, except for platelet count. The platelet count of LMWH-treated blood was lower than that of EDTA-treated blood, and the decrease in platelet count in the former was due to platelet aggregation. Prothrombin time tests could be performed with plasma prepared from LMWH-treated blood, although with such blood the prothrombin time was prolonged. Chemistry tests could be performed for all 18 parameters. These results suggest that LMWH is a candidate for use for hematology testing (with the exception of platelet count), coagulation testing, and chemistry tests.
