Abstract: The present invention relates to a method for performing a quantitative or qualitative analysis by a two-phase rapid test. In the method a signal reagent is placed into a container made of non-absorbing material, the container being located separate from the rapid test device. The signal reagent is reacted with the analyte(s) present in a test sample by adding the liquid test sample into the container. A reaction solution is obtained, which is then contacted with the rapid test device, wherein a detectable signal is developed. Subsequently, the development of the signal is monitored and read continuously.

Abstract: The invention relates to a sampling tube to which is fastened a memory device which is used to record data used to identify said sampling tube and/or its contents and the memory device being fastened to said sampling tube with a mounting piece. A mounting piece in accordance with the invention has a part which remains on the sampling tube or its part when the electronic memory device is attached to the sampling tube and/or detached from the sampling tube.
