Dried blood spot collection device

A method of making a dried blood spot collection using a device comprising:

• a body defining an elongate capillary passage extending from an outer surface of the body to an interior cavity of the body, the capillary passage having a longitudinal central axis, an inlet end, and an outlet end, the capillary passage configured to hold an amount of blood sufficient to at least saturate an absorbent disk and configured to move the blood from the outer surface of the body to the interior of the body for application to the absorbent disk maintained within the interior cavity of the body;
• a platform coupled to the body within the interior cavity, the platform having a surface for holding the absorbent disk in a fixed position on a region of the platform;
• a manually actuatable component mounted in the body, the manually actuatable component adjustable up and down along the longitudinal central axis of the capillary passage between a first position and a second position relative to the body, wherein:
• in the first position, when an absorbent disk is mounted in the fixed position on the platform, the outlet end of the capillary passage is not in physical contact with the absorbent disk,
• in the second position, when an absorbent disk is mounted in the fixed position on the platform, the outlet end of the capillary passage is in physical contact with the absorbent disk,
• the longitudinal central axis of the capillary passage is normal to the surface of the platform in both the first position and the second position;
• the method comprising:
• introducing blood into the capillary passage;
• and
• actuating the manually actuable component to cause the platform to move from a first position in which the absorbent disk is not in physical contact with the outlet end of the capillary passage to a second position in which the absorbent disk is in physical contact with the outlet end of the capillary passage to absorb blood from the capillary passage.
