研究组 & 干预措施
BD HPV assay on Viper LT
The BD HPV specimen will be tested with the BD HPV assay on the Viper LT instrument. The results will be compared to adjudicated histology. A portion of the specimens will be compared to a composite comparator generated by results of both Digene HPV and a polymerase chain reaction (PCR) sequencing test.
Device: BD HPV assay on Viper LT The BD HPV specimen will be tested with the BD HPV assay on the Viper LT instrument. The results will be compared to adjudicated histology. A portion of the specimens will be compared to a composite comparator generated by results of both Digene HPV and a polymerase chain reaction (PCR) sequencing test. Colposcopy/biopsy will be performed on all subjects.

结局指标
主要结局
Sensitivity
时间窗: 18 months
Sensitivity of the BD HPV Assay for the detection of cervical disease as defined by Cervical Intraepithelial Neoplasia (CIN). Sensitivity is calculated: Number of subjects with a positive BD HPV test with adjudicated histology results of CIN2 or greater divided by the total number of subjects with adjudicated histology results of CIN2 or greater. Similar for CIN3 or greater.
Specificity
时间窗: 18 months
Specificity of the BD HPV Assay for detecting cervical disease as defined by Cervical Intraepithelial Neoplasia (CIN). Specificity is calculated: Number of subjects with a negative BD HPV test with adjudicated histology results of less than CIN2 divided by the total number of subjects with adjudicated histology results of less than CIN2. Similar for CIN3 or greater.
PositivePredictive Value
时间窗: 18 months
Positive Predictive Value (PPV) of the BD HPV Assay for detecting cervical disease as defined by Cervical Intraepithelial Neoplasia (CIN). Positive Predictive Value is calculated: Number of subjects with a positive result for the BD HPV test and adjudicated histology results of CIN2 or greater divided by the total number of subjects with positive result for the BD HPV test. Similar for CIN3 or greater.
Negative Predictive Value
时间窗: 18 Months
Negative Predictive Value (NPV) of the BD HPV Assay for detecting cervical disease as defined by Cervical Intraepithelial Neoplasia (CIN). Negative Predictive Value is calculated: Number of subjects with a negative result for the BD HPV test and histology results less than CIN2 divided by the total number of subjects with negative results for the BD HPV test. Similar for CIN3 or greater.
Likelyhood ratio
时间窗: 18 months
Likelihood ratio for the detection of cervical disease as defined by cervical intraepithelial neoplasia (CIN). The likelihood ratio for each BD HPV test outcome summarizes how many times more (or less) likely subjects with the disease (e.g. CIN2 or greater and CIN3 or greater) are to have that particular HPV test outcome than subjects without the disease.
Absolute Risk
时间窗: 18 Months
Absolute risk for the detection of cervical disease as defined by cervical intraepithelial neoplasia (CIN). The Absolute Risk (AR) of the disease(e.g., CIN2 or greater and CIN3 or greater) for each BD HPV test outcome is the probability of the disease for that particular BD HPV test outcome.
Relative Risk
时间窗: 18 Months
Relative Risk of the detection of cervical disease as defined by cervical intraepithelial neoplasia (CIN). Relative Risk is the ratio between two different absolute risks. The relative risk of having a disease (e.g., CIN2 or greater and CIN3 or greater), will be evaluated to compare two different BD HPV Assay test outcomes.
Positive Percent Agreement
时间窗: 18 Months
Positive percent agreement of the BD HPV Assay as compared to a composite HPV comparator incorporating results for the Digene Hybrid Capture 2 (HC2) HPV test and PCR/Sequencing on both strands of the PCR amplicon (bidirectional sequencing). Positive percent agreement is calculated: Number of subjects with a positive BD HPV test with composite comparator positive divided by the total number of subjects with composite comparator positive.
Negative PercentAgreement
时间窗: 18 months
Negative percent agreement of the BD HPV Assay as compared to a composite HPV comparator incorporating results for the Digene HC2 HPV test and Polymerase Chain Reaction (PCR)/Sequencing on both strands of the PCR amplicon (bidirectional sequencing). Negative percent agreement is calculated: Number of subjects with a negative BD HPV test with composite comparator negative divided by the total number of subjects with composite comparator negative.
Non reportable rate
时间窗: 18 months
.Non-reportable rate of BD HPV test. Non-reportable rate is calculated as the number of non-reportable BD HPV test results divided by the total number of BD HPV test results
