Final answer:
In a cervical biopsy using acetic acid, abnormal cervical tissue will turn white, which allows for identification of areas that may require further analysis.
Step-by-step explanation:
When using acetic acid during a cervical biopsy, the abnormal cervical tissue will turn white. This reaction is commonly referred to as an acetowhite reaction and is used as a diagnostic tool to highlight areas of abnormal tissue growth that may require further examination. By applying acetic acid to the cervix, areas with abnormal cell growth or pre-cancerous conditions may become visible to the healthcare provider, who can then take a targeted biopsy for more definitive analysis.
