title: [Heparin Sodium Reference Standard (Control 991) of National Institute of Health Sciences].
abstract: The National Institute of Health Sciences Reference Standard for Heparin Sodium (Control 991) was prepared. The potency of heparin sodium for the candidate reference standard was assayed against "Heparin Sodium Reference Standard (Control 871)" by JP Method in collaboration with 4 laboratories, and estimated as 1,453 +/- 25 units per ampoule. The filling amounts of heparin sodium in ampoule was estimated as 7.46 +/- 0.15 mg per ampoule, and the precision of filling into ampoule was about 2.0% as C.V. Based on the above results, the candidate was defined as 1450 units per ampoule, and was authorized as the Heparin Sodium Reference Standard (Control 991) of the National Institute of Health Sciences.
