<p>The Annual Statistics of Scientific Procedures on Living Animals in Great Britain
2013 report a total of 52,444 procedures were conducted on 6,725 animals with ‘Direct
diagnosis’ as the primary purpose. This represents a 3% increase on the total number
of procedures, in this category, in 2012 and a 1% increase on the number of animals,
in this category, in 2012. Most procedures reported under the category ‘Direct diagnosis’
involve the collection of blood or blood products from either non-immunised animals
or animals immunised against various antigens. The procedure of blood collection is
classified as being of low severity and, with appropriate licence authority, may be
repeated <br>many times in the same animal. The products from these procedures, including
