Abstract

A device to determine human chorionic gonadotropin (hCG) in urine is described. It includes: a) a first area, consisting of a material able to draw urine by capillarity, on which an hCG bioselective colored agent is absorbed, an end of said first area, to be dipped in urine, while the other end contacts with the following b) area; b) a reading area which contacts the previous one and an area of a material able to assure the capillary flow of urine, on which there is bound: 1) a protein able to selectively bind hCG and possibly; 2( hCG (positive reagent control) and 3) an inert protein (negative reagent control) disposed so as to form, after the reaction with the bioselective colored reagent present in a), two different figures which can be visually detected according to the positivity of the analysis: c) a further area, an end of which contacts the previous one, of a material able to assure the capillary flow of urine towards the other end containing an indicator revealing the occurred passage of urine through the A device. According to the invention, pregnancy analysis becomes easier because the a device is dipped just once in the sample to be tested and because the results are simple to read.
