Abstract
Disclosed is a method for obtaining cells from the uterine cervical canal (external os) by inserting a conically tapered brush into the canal and rotating the brush to cause cells to become entrapped by the brush. The brush employed utilizes a spiral wound bristle of 15-20 millimeters in length and of 3 to 7 millimeters in diameter at its widest end. The bristles are formed primarily of a nylon having a maximum diameter of 0.06 millimeters, and relatively soft such as that of a soft toothbrush to more readily bend and avoid damaging in the tissues.
