The invention discloses a dry chemical bigeminal
reagent strip for simultaneously detecting glutamic oxalacetic
transaminase and glutamic-pyruvic
transaminase. The dry chemical bigeminal
reagent strip is characterized in that two sections of test paper pads are contained, and each test paper pad is composed of four
layers of films which are the
diffusion film on the
surface layer, the rapid
glass fiber filter film on the second layer, the mixed
fiber film on the third layer and the reaction film on the bottom layer. Corresponding reactants are adsorbed on the reaction films, and when a detected object is added into a sample inlet hole, the detected object is uniformly dispersed on the two test paper pads through the
surface diffusion films and then reaches the reaction films on the bottom layer to carry out reacting. Meanwhile, a lower supporting layer of the
reagent strip is provided with two test holes which are connected with the reaction films on the bottom layer respectively, in the reacting process, dihydrocoenzyme I (NADH) adsorbed on the reaction films is oxidized into NAD+, the descend range of the
absorbance at 340 nm is tested, and therefore the content of the corresponding tested object is obtained. The
reagent strip can be used for rapidly determining the activity of glutamic oxalacetic
transaminase and glutamic-pyruvic transaminase in the human
whole blood or serum or
plasma, and therefore clinical monitoring and
adjuvant therapies of liver diseases are promoted.
