Abstract: Immunoassay analytical test apparatus for allergy diagnosis, which apparatus comprises a zone for receiving a sample containing an analyte, a zone for receiving a mobile phase (the zone may be the same as the sample receiving zone, or different thereto), a detection means for permitting detection of the analyte by immunoreaction, a first flow path for flow of the analyte in the mobile phase from the sample receiving zone to the detection means, and a second flow path permitting flow of a mobile phase to the detection means.

Abstract: The apparatus for collection of a liquid sample (such as a sample of body fluid) includes a tube with a hollow bore extending longitudinally between a first open end and a second open end. The second end is longitudinally spaced from the first open end and the first end has a capillary opening for uptake of the liquid sample by capillary action. The capillary opening has a first axis and a second axis substantially perpendicular thereto. The first axis has a length greater than the internal diameter of the bore, and the second axis has a length less than the internal diameter of the bore. In use the capillary opening is contacted with the liquid sample to be collected. The liquid sample is taken up by capillary action into the bore without introduction of air into the bore.
