Concentrations <strong>of</strong> allergens used for skin testing in horses in Australia have been<br />

based on those used for small animals, which were loosely derived from human<br />

studies and modified according to reactions in normal dogs in early work (10). In<br />

Australia, most allergens (grass, tree and weed pollens, moulds and insects) from<br />

Greer are tested at a concentration <strong>of</strong> 1000pnu (Protein Nitrogen Units), with some<br />

minor exceptions (15, 16). Dust mite and various other allergens are provided in<br />

weight per volume measurements (w/v), and the standard testing concentration for<br />

these is 1:10 000 which is roughly equivalent to 1000pnu.<br />
