The present invention is a device for conveniently collecting and storing liquid samples, as well as applying an aliquot of the sample to a test device, such as a lateral flow immunoassay. The present invention comprises an absorbent swab and a dropper container containing an expression means for expressing the collected sample from the swab. After the collected sample has been expressed into the reservoir of the device, the device is capped. The device can be inverted over a test device, the sides of the reservoir squeezed and an aliquot of the sample applied, in a drop-wise manner, to the sample application well of the test device. The present invention is particularly useful for collecting viscous samples, such as saliva or oral fluid, in a drug of abuse testing setting.
