## Abstract

Disclosed is a system for stabilizing analytes in blood samples for use in delayed extraction and tests in human and veterinary applications. The system can include a device for holding a blood sample, a desiccant compound, a deoxygenation compound, and a sealable container for holding there within, a in sealed environment, the device for holding the blood sample, the desiccant compound and the deoxygenation compound.

## Claims

### Claim 1

A system for stabilizing analytes in blood samples for use in delayed extraction and tests in human and veterinary applications, said system comprising:
a device for holding a blood sample; a desiccant compound;
a deoxygenation compound; and
a sealable container for holding there within, a in sealed environment, said device for holding said blood sample, said desiccant compound and said deoxygenation compound.

### Claim 2 (depends on 1)

The system of claim 1, wherein said device for holding said blood sample further comprises an enclosure comprised of a first region for holding an absorbent medium and a second region for holding said desiccant compound, wherein said enclosure allows for free air circulation between said first region and said second region.

### Claim 3 (depends on 2)

The system of claim 2, wherein said absorbent medium further comprises cellulose-based paper.

### Claim 4 (depends on 2)

The system of claim 2, wherein said absorbent medium further comprises synthetic paper.

### Claim 5 (depends on 2)

The system of claim 2, wherein said first region further having a hole that exposes a portion of said absorbent medium for allowing said blood sample to be directly deposited onto said portion of said absorbent medium.

### Claim 6 (depends on 2)

The system of claim 2, wherein said first region and said second region are linked via a plurality of air circulation channels.

### Claim 7 (depends on 2)

The system of claim 2, wherein said enclosure is comprised of two parts having a locking mechanism that allows the two parts to lock to one another to form a volume therewithin that forms at least said first region and said second region.

### Claim 8 (depends on 1)

The system of claim 1, wherein said device for holding said blood sample, further comprises a dried blood spot device.

### Claim 9 (depends on 8)

The system of claim 8, wherein said dried blood spot device further comprises cellulose-based cards.

### Claim 10 (depends on 8)

The system of claim 8, wherein said dried blood spot device further comprises synthetic paper-based cards.

### Claim 11 (depends on 1)

The system of claim 1, wherein said device for holding said blood sample, further comprises a fiber stick having an absorbent paper portion for absorbing a preset amount of blood.
