1. An apparatus for collecting a liquid sample, comprising:
a first chamber for collecting a liquid sample for a first detection, wherein the first chamber has an opening; and
a second chamber for collecting the liquid sample for a second confirmatory detection;
wherein the first chamber and the second chamber can be detachably combined, assembled or connected, the first chamber comprises a test element therein for the first detection, and a cover body configured to cover the opening of the first chamber comprises a sealing element;
wherein when the first chamber collects the liquid sample, the first chamber is in liquid communication with the second chamber, and a portion of the liquid sample enters the first chamber and another portion of the liquid sample enters the second chamber, and wherein the sealing element makes the first chamber and the second chamber in a liquid non-communication state before the second chamber leaves the first chamber or before the second chamber is separated or is about to be separated from the first chamber;
wherein the apparatus further comprises a piercing element, and the piercing element is configured to pierce the sealing element so as to change the state from liquid non-communication to liquid communication between the first chamber and the second chamber;
wherein the apparatus further comprises a connecting channel, the second chamber is detachably combined, connected or assembled with the first chamber via the connecting channel, when the connecting channel is not sealed when the second chamber does not leave the first chamber, and the connecting channel is sealed after the second chamber leaves the first chamber.
