The absorbent pad enables the usage of larger example volumes, which results in enhanced test level of sensitivity. One of the most preferred absorbing pads are made of cellulose filters. The main role of the conjugate pad is to hold the detector particles and also keep them functionally stable up until the test is performed. This is guaranteed by the structure of the conjugate buffer, consisting of carbs, which act as a chemical and a resolubilization representative. When the conjugate fragments are dried out in the existence of sugar, the sugar particles form a layer around them maintaining their biological frameworks. When the sample gets in the conjugate pad, the sugar particles quickly dissolve bring the bits right into the liquid stream.
