Regional thromboplastin standardisation using a human brain extract.
The preparation, regional distribution and standardisation of an acetone-dried extract of human brain thromboplastin was prospectively evaluated. The programme was shown to be easy to implement within the constraints of the World Health Organisation recommendations and offers a practical alternative to a national standard in countries where the cost of distribution and lack of expertise in preparing such material are limiting factors.
