A sampling probe, having a housing, with a flange at housing's proximal end, and an internal step ring including a protruding follower tab toward housing's distal end. The sampling probe further includes a shaft inside the housing, with a brush at shaft's distal end and a handle at shaft's proximal end. The shaft includes a solid proximal section, and a spirally grooved distal section, engaging the housing's follower tab. A retracting compression spring is positioned on the spirally grooved distal section of the shaft inside the housing. With the sampling probe distally inserted in a vagina canal for a Pap smear, pushing the shaft handle distally, the brush at the end of the shaft protrudes out of the housing rotationally, taking a cell sample, followed by the retracting compression spring retracting the brush back into the housing when the shaft handle is released, completing the Pap smear.
