    Journal: J Reprod Med; 1991 Aug; 36(8):581-6. PubMed ID: 1941800.
    Abstract:
    A study was designed to test specimen adequacy and the detection of disease using two new cervical cytologic sampling devices, the Cervex-Brush and Cytobrush plus a modified Ayre spatula. Two clinicians used each device at random. The laboratory was blind to the sampling method, and the results were compared with those from control samples (Ayre spatula with cotton swab or alone). The 567 test samples were compared with 569 age-matched control samples. The Cervex-Brush and Cytobrush plus spatula were comparable in detecting disease, and both were improvements over the control method. Both the Cervex-Brush and Cytobrush plus spatula produced more consistent good smear quality across the age range studied than did the control method, which resulted in a lower percentage of good-quality smears in older women. Use of the Cytobrush plus spatula and the control method produced smear results the quality of which varied considerably with each clinician.
