The Department of Health today reminded the public that there is currently insufficient scientific evidence to confirm the reliability of using menstrual blood for cervical screening.

It made the statement in response to claims by businesses that menstrual blood can be collected using sanitary pads, then self-sampled and mailed to a laboratory for Human Papillomavirus (HPV) testing.

Regarding self-collected menstrual blood or urine samples, the department said there is currently insufficient scientific evidence in Hong Kong or internationally to demonstrate the feasibility and reliability of such a cervical screening method, adding that it will continue to review the latest scientific evidence in this field.

However, the department noted that in addition to healthcare professionals collecting cervical samples for cytology or HPV testing, the World Health Organization recommended that vaginal self-sampling for HPV testing as another reliable method for cervical screening.

Therefore, from June 2024, the department launched a Pilot Scheme on HPV Testing of Self-collected Samples at 11 Maternal & Child Health Centres (MCHCs) that provide family planning services in order to explore the feasibility and acceptability of vaginal HPV self-sampling.

The department said women aged 25 to 64 who have had sexual experience should consult healthcare professionals to select and undergo appropriate cervical screening methods regularly.

Women planning to receive cervical screening at any of the MCHCs may make an appointment via the 24-hour hotline at 3166 6631.
