2. Obtain an adequate sampling from the ectocervix using a plastic spatula and endocervical brush.

3. Rinse the spatula into the PreservCyt Solution in the collection vial by swirling the spatula vigorously 10 times. Discard the spatula.

Interpretive

Reference Range:

Negative or abnormal cells consistent with neoplasia, dysplasia, or inflammation.

Note: Inflammatory reaction may preclude hormonal evaluation. Occasional aggressive lesions of squamous epithelium of cervix can be missed, especially if patient has only single examination. Maturation index results are reported in percentages, i.e., 0/70/30, indicating 0 parabasal, 70 intermediate, and 30 superficial cells. Interpretation depends upon individual clinical situation. An interpretive report with follow-up recommendations may be rendered by the pathologist.
