Why is there a shortage of blood

1. State restrictions on the problem, this problem is more tangled, due to South America, North America and other places from the beginning of 2001 burst of mad cow disease and other epidemic, the relevant origin of the blood restrictions on imports, until this year's North American re-release. However, due to foreign serum testing standards and domestic standards are different, so far there is no relevant implementation details. The Australian source of serum because last year detected a virus, coupled with this year's bilateral trade agreement between China and Australia expired, the new has not yet introduced, so within six months basically no bottle of formal imported serum. So the current market in the sale of two kinds of serum: one is the inventory, only a few large serum companies to import and come in a regular stock, another or informal channels or fake.

As early as March 1, 2001, the Ministry of Agriculture, the former State Administration for Entry and Exit Inspection and Quarantine announced that in order to prevent the introduction of mad cow disease in China, banned directly or indirectly from the occurrence of mad cow disease in countries or regions of cattle, cattle embryos, Beef products (including bovine internal organs) and their products, ruminant-derived feed. The announcement of the time, the occurrence of mad cow disease only the United Kingdom, Ireland, Switzerland, France and other 13 countries. The announcement also states that in the future countries that have newly developed mad cow disease will be automatically included in the list. On December 28, 2003, the US Department of Agriculture informed the World Organization for Animal Health that confirmed that mad cow disease occurred in Washington State. The United States and therefore in January 14, 2004 into the above list.

2. Decreased serum production, limited by the supply of blood source origin, climate and environmental effects, reduced serum production.

3. The surge in serum consumption, the rapid development of Chinese life science research, research funding increased year by year, hot research projects need a lot of cell culture, the domestic bio-industry is ushering in the new development peak.
