Abstract
A blood sampling device is provided having holder with a manipulating end and an absorbent probe on the opposing end. The probe is made of pyrolyzed porous carbon sized to directly absorb a predetermined volume of liquid, preferably biological fluid, in a predetermined amount of time. Shapes for absorbent probes of differing materials are provided.

17. A process for use in testing a blood sample, comprising:
-
placing an absorbent probe in physical contact with a blood sample, the absorbent probe being made of a carbonized, porous carbon material and connected to a holder, the absorbent probe being configured to absorb a predetermined maximum volume of blood of about 1 μ
l to about 100 μ
l, the absorbent probe having a majority of its exterior surface exposed and accessible for absorption of blood from a surface;maintaining a portion of the exterior surface of the probe in contact with the blood sample until the predetermined amount of blood is absorbed by the probe; removing the probe from contact with the blood; and drying the blood in the probe without contaminating the blood. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A kit for collecting body fluids, comprising:
-
a plurality of holders each having a manipulating end and opposite thereto an absorbent probe made of a hydrophilic, porous carbon material configured to absorb a predetermined volume of about 1 μ
l to about 100 μ
l of blood within about 1-5 seconds, the probe having a majority of its exterior surface exposed for potential use in absorbing the blood;a container having a plurality of compartments, each configured to releasably receive a different one of the holders and its probe, the container and holder configured to prevent the probes from abutting the compartment within which the holder and probe are placed, the container having openings in each compartment to allow air to enter each of the compartments and reach the probe within the compartment with which the openings are associated. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
