Abstract
A test of uremia was devised for the postmortem examination of meat inspection. In it, muscle was used as a sample to estimate the amount of ammonia produced from muscle decomposed by urease. The urea nitrogen determined by this test was compared with those determined in the serum and the ophthalmic chamber fluid by the conventional methods. As a result, there were significant correlations between the former and both of the latter. A sufficient practicability of the new test was demonstrated.
