Abstract

A sample collector and test device is disclosed. The sample collector and test device may be used together as a diagnostic tool for collecting and assay of analytes contained in a sample. A sample collector is also disclosed which may be used with existing sample containers and or test devices. The sample collector may indicate sample adequacy when a sufficient volume of sample has been collected for assay and may also include a sample retaining feature which retains a portion of expressed sample for confirmatory testing, if desirable. The sample collector may also include a mechanism for expressing sample in a sample collector and/or test device. A test device is also disclosed for retaining and assay of an expressed sample. The disclosed test device may be used with existing sample collectors. In a preferred embodiment, test device is used with a preferred sample collector. Test device may include a locking feature for locking a sample retained on a sample collector or test device may be used to receive expressed sample collected from a syringe or another suitable sample delivery device.

Claims

1. A sample collection device for assay comprising:

a collector portion having a first end and a second end,

the collector portion second end having a base being movable relative to the collector portion first end;

a plunger arm coupled to the base and including a first diameter portion and a second diameter portion; and

an expandable sponge coaxially disposed on the first diameter portion and on the second diameter portion of the plunger arm between an end wall of the collector portion and the base; and

wherein the plunger arm is moved relative to the collector portion first end such that plunger arm reconfigures the sponge to a smaller size and discharges a portion of the sample for assay.
