Smear Test

A smear test, also known as cervical screening (previously known as Pap smear / Pap test), is a screening procedure used to detect the presence of human papilloma virus on the cervix and abnormal cells in the cervix, which is the lower part of the uterus that opens into the vagina. The test helps in the early detection of cervical cancer or pre-cancerous changes, allowing for timely intervention and treatment.  During a smear test, a healthcare provider will gently insert a speculum into the vagina to visualize the cervix. They will then use a small brush to collect a sample of cells from the cervix. The collected cells are then sent to a laboratory for analysis. Here are some key points to know about smear tests:


The primary purpose of a smear test is to detect early signs of cervical cancer or pre-cancerous changes. Detecting and treating these changes early can significantly reduce the risk of developing cervical cancer.

Recommended Age and Frequency

The age at which smear tests are recommended may vary depending on the country and guidelines. In many countries, screening typically starts at around age 21 or when a woman becomes sexually active. The NHS does not start offering smear tests to women until the age of 25. The frequency of smear tests also varies, but generally, it is recommended every three to five years for most women. However, the recommended frequency may change based on individual risk factors or if abnormalities are found in previous tests.

HPV Testing

A smear test also includes testing for the presence of high-risk types of the human papillomavirus (HPV). HPV is a sexually transmitted infection that is the leading cause of cervical cancer. Combined testing for HPV and abnormal cells can provide a more comprehensive assessment of cervical health.


To ensure accurate results, it is generally recommended to avoid sexual intercourse, using vaginal creams, douching, or using tampons for at least 24 hours before a smear test. It is also important to schedule the test when you are not on your period.

Discomfort and Side Effects

The smear test itself may cause some mild discomfort or pressure, but it is usually not painful. Some women may experience slight spotting or mild cramping afterward, but these symptoms typically subside quickly.


If the results of a smear test indicate abnormal cells or the presence of HPV, further diagnostic procedures or follow-up tests may be recommended. These may include colposcopy (an examination of the cervix using a magnifying instrument) or a biopsy to obtain a more detailed evaluation of the cervical tissue.

It is important to have regular smear tests as recommended by your healthcare provider to ensure early detection and appropriate management of any cervical abnormalities. Discussing the specific screening recommendations and schedule with your healthcare provider is crucial to tailor the screening plan to your individual needs and circumstances.
