Abstract
A method for collecting biological specimens using a swab of the type consisting of a rod terminating in a tip covered with fiber with hydrophilic properties to allow absorption of said specimens, wherein said fiber covers said tip in the form of a layer deposited by flocking.
Claims30
A biological specimen collection swab, comprising:
- a rod terminating in a tip, the tip being shaped with a rounded geometry;
- and
- a layer of fibers disposed on a surface of said tip by flocking with a flocking technique in which the fibers were deposited in an ordered manner on the surface of the tip of the rod, the layer of fibers having a fiber length of 0.6 to 3 mm and being configured to have capillarity hydrophilic properties and configured to and having an amount of fiber capable of absorbing by capillarity a quantity of 40 μl of liquid biological specimen in said layer of fibers on the tip of the rod, the liquid absorption capacity of said layer of fibers being at least 40 μl, and
- wherein said swab is configured to collect said biological specimen from a human for analysis.
