In the Multiphasic Health Check-up System, medical laboratory testing has been changing lately to utilize a small and compact type of testing systems. The system uses heparinized blood for chemistry tests to reduce laboratory's workload and sample volume. The dana-paroid, a mixture of glycosamino-glycans (Heparan sulfate), has been used clinically for treatment of patients with disseminated intravascular coagulopathy instead of heparin sulfate. Heparin has been used for routine laboratory tests, although it has a strong activity of platelet aggregation. This study aimed to examine availability of Danaparoid for routine hematology tests as a substitute of heparin. Although Danaparoid induced platelet aggregation directly, the reaction was weaker than that of heparin. The platelet count of Danaparoid blood was decreased after five minutes of mixing. Addition of MgSO<SUB>4</SUB> or of kanamycin sulfate to Danaparoid blood was able to prevent this decrease. When Danaparoid blood was applied to chemistry tests, major chemistry test data showed acceptable results, although level differences were observed slightly. It was concluded that Danaparoid would be a good candidate for a universal anticoagulant for both chemical and hematological laboratory tests.
