Claim 10:
11. A sample extraction cassette for point-of-care molecular testing for a target in a sample provided on a swab, comprising:
a case having:
a chamber configured for receiving the swab;
a wash zone configured for receiving a wash fluid therein; and
a reaction zone configured for receiving a reaction fluid therein, the reaction fluid reacting with the target;

a membrane having a contact portion, the membrane slidably receivable into the case and being moveable between:
a transfer position wherein the contact portion of the membrane communicates with the sample provided on the swab when the swab is received in the chamber such that at least a portion of the sample is transferred to the contact portion;
a wash position wherein the contact portion of the membrane communicates with the wash zone; and
a reaction position wherein the contact portion of the membrane communicates with the reaction zone; and

a slider slidably connected to the case and operatively connected to the membrane, wherein sliding of the slider relative to the case moves the membrane between the transfer position, the wash position and the reaction position.
