My letter says that I am HPV negative, but you have not checked my cells for changes. Why haven't you looked at my cells?

Cell changes are caused by HPV. If there is no HPV detected on your test we do not need to look at the cells. If  HPV is not found we do not need to examine your cells as your risk of developing cell changes is extremely low. We know that some individuals find this worrying, but a test showing no HPV is more reliable than finding normal cells.
