<p>A method of producing diagnostic test strips for detecting given components present in biological liquids, which strips comprise a solid support medium carrying at least two reagents for effecting a given color test reaction on wetting contact with a liquid analysate. A water-insoluble support medium chemically inert to reagent inks is successively printed with a multitude of dots of each reagent ink so as to thereby form at least two separate patterns of printed dots, the reagent ink dots of each pattern being dried after printing and being arranged in closely spaced relationship with one another and with the dots of each different pattern, so that the printed dots of each reagent ink are separately arranged between the dots of each different reagent ink without contacting the dots of different inks, and the reagents in the respective dry dots are thereby kept separate from one another, while allowing said reagents to diffuse along the surface of the support medium to mutually interact thereon in the presence of liquid analysate. After printing, the sheet may be cut up into a plurality of test strips of desired shape and size.</p> |
