Gynecologic Cytology Outcomes: Biopsy Correlation Performance QT5
The correlation of cervicovaginal cytology (Pap test) findings with cervical biopsy results is a staple in the cytopathology laboratory’s quality assurance program. By monitoring this correlation, the laboratory can identify potential problems requiring improvement, thereby ensuring better patient results.
Quantify the correlation between the findings of cervicovaginal cytology and corresponding histologic material.
Participants are asked to record information on true-positive, false-positive,
and false-negative cytology-biopsy correlations on a monthly basis. False-negative
correlations will be separated into four error categories on a monthly basis. Participants
will also record the biopsy diagnoses for Pap tests with an interpretation of atypical
squamous cells (ASC-US and ASC-H) or atypical glandular cells (AGC). This
monitor includes patients for whom a cervical biopsy specimen is submitted to
the laboratory and for whom a satisfactory or satisfactory but limited Pap test
has been submitted within three months previous to the biopsy or at the time
of the biopsy.
- Predictive Value of a Positive Cytology (%)
- Sensitivity (%)
- Screening/Interpretive Sensitivity (%)
- Sampling Sensitivity (%)
- Percent Positive for ASC-US Interpretations
- Percent Positive for ASC-H Interpretations
- Percent Positive for AGC Interpretations
Input forms for quarterly data will be sent to participants approximately three weeks prior to the quarter.
