Abstract
There is disclosed a dry analytical element for .alpha.-amylase in a fluid sample which comprises the analytical element including a starch capable of forming a complex with iodine, an iodine compound and an oxidizing agent, and the iodine compound and the oxidizing agent are disposed in the element so that iodine may be liberated therefrom when the fluid sample is brought into contact with the analytical element. The analytical element of this invention enables an easy, prompt and accurate dry quantitative analysis of a component in a fluid sample, especially a biological fluid sample by the use of visible light with the aid of a spectrophotometer.
Claims21
