Some specific properties of the Dry Chemistry is better than the Wet Chemistory, Such as need less capacity of sample, etc. We determined the Biochemistory subjects of ALT, AST, BUN GLU,Ca 2 and TB witch in the rabbit's plasma by Dry Chemistory, and found that the linear regression and simple correlation between the Dry Chemistory and the Wet Chemistory was satisfactory. The dilution metering, repeate experiment and reclamate experiment was satisfactory too. The results suggested that ALT, AST, BUN and GLU witch in rabbit's plasma can be determined by the Dry Chemistory. The linear regression of Ca 2 especially TB was not satisfactory. This problem will be reseached in the future.
