Abstract: The present invention provides an apparatus for collecting and detecting liquid samples comprising a first chamber and a second chamber. The first chamber is used for collecting liquid samples for initial detection, and the second chamber is used for collecting liquid samples for second confirmatory detection. The first chamber and second chamber of the apparatus are detachable. When a second confirmatory detection is necessary, the second chamber can be separated from the first chamber, and then sent to a detection agency for confirmatory detection. It can avoid the contamination of liquid samples caused by contacting with test strip of a traditional apparatus; thus, it can effectively reduce the space required for storing liquid samples and greatly reduce the risk of leakage of liquid sampled during transportation.

Abstract: The present invention provides an apparatus for detecting an analyte in liquid sample, including a channel for arranging the test strip, with one opened end and the other end is closed, wherein the channel includes an anti-flooding structure where the cross sectional area of the channel is reduced. The apparatus provided in the present invention can prevent the flooding phenomenon of the test strip, and reduce the error rate.
