I've never heard of jumping to a biopsy right after 1 abnormal cell test. Usually they just do another test to see if the results are the same first. Its the most coservative, least invasive and least expensive route. There are many reasons why they can come back normal and the majority are benign. I would insist on another pap smear just to rule out any mistake on the previous test. I've had two in my lifetime come back "abnormal" and my GYN did another test and it came back normal.
