In a solid phase immunoassay, e.g. RAST or PRIST, the sensitivity can be substantially increased by reducing the volume of liquid in which the indicator (e.g. <125> I anti-IgE) is contained, preferably to the saturation volume of the paper carrier. If the volume of sample is also similarly reduced, the incubation time can be reduced to as little as 5 minutes without loss of sensitivity in comparison with conventional tests. A washing device for the paper carrier is also disclosed, together with immunoassay kits for use in the method of the invention. |
