Basal Index

The basal index (BI) is an indicator that is used to assess the condition of the cervix and vagina. It is determined by counting the number of basal and parabasal cells in a smear from a vaginal scraping.

Basal cells are the deepest cells of the cervical epithelium. They are responsible for producing mucus that protects the cervix from infections and other damage. Parabasal cells are located just above the basal cells and are also involved in mucus production.

An increase in the number of basal cells may indicate infection or inflammation in the cervix. This may be due to bacterial vaginosis, candidiasis, gonorrhea or other infectious diseases.

A decrease in the number of basal cells can also indicate health problems. This may occur due to hormonal changes such as menopause or taking hormonal contraceptives. It may also be due to stress or overwork.

To determine the basal index, it is necessary to analyze a vaginal smear. The gynecologist will take a tissue sample from the cervix and determine the percentage of basal and parabasal cells. If the test results show an increase or decrease in the number of these cells, this may indicate possible health problems and requires additional examination.

Assessing the basal index can help the gynecologist determine the cause of changes in the cervical epithelium and prescribe appropriate treatment.

The basal index is a colpocytology indicator that determines the percentage of basal and parabasal cells in a woman’s vaginal smear. These cells are the first decidual cells to appear in the first trimester of pregnancy, and they mediate trophoblastic growth in the uterus.
