There are over 150 different strains of HPV – some are low risk and others are high risk. The high risk strains, particularly strains 16 and 18, are responsible for about 70% of cases of cervical cancer. For most people, the virus clears on its own without any treatment. In some cases, an HPV infection with a high risk stain can potentially lead to cancer.
The test kit screens for 14 high-risk strains of the virus: HPV16 and HPV18, which cause the vast majority of cervical cancer cases – and 12 additional high risk types.
