Three cervical samples will be collected at entry (one dry and two liquid-based). Sample retaining or discharge will depend on HPV test (done in first liquid sample) results. If HPV positive (and 2% of HPV negatives): 1) the dry sample will be used for the E6 protein strip test, 2) the first liquid sample remains will be used for liquid-based cytology and the p16/ki67 test and, 3) 10 aliquots from the second liquid sample will be stored. If HPV negative: 1) the dry sample will be stored for the E6 strip test until the end of the study. Testing will be done based on evidence towards usefulness in primary screening, 2) two aliquots from the first liquid sample will be stored and, 3) the second liquid sample will be discharged. At initial colposcopy, a cervical sample (6 aliquots) and a 10mL blood sample (serum, plasma and buffy-coat) will be collected and stored. All stored samples will be used for testing of triage techniques, either currently available or develop in the near future.
