title: [The human chorionic gonadotrophin reference standard (Control 941) of the National Institute of Health Sciences].
abstract: Raw human chorionic gonadotrophin material was examined for preparation of the "Human Chorionic Gonadotrophin Reference Standard (Control 941)". The candidate material was assayed against the 3rd International Standard by the rat ovarian weight method. The potency of the new standard was defined as 1180 international units per ampoule as the result of 18 assays in four collaborative laboratories.
