"A regular sanitary pad topped with a blood sample strip can pick up human papillomavirus (HPV), which causes most cases of cervical cancer, and could be used by women at home, the results of a study indicate. Currently, most women undergo cervical screening under the care of a medic, who collects a sample via a brush inserted into the vagina. But millions of women invited for screening do not attend."
"Each provided three samples for testing: a menstrual blood sample collected using a sanitary pad and strip, a cervical sample collected by a clinician, and an extra sample collected by a health worker for processing in a lab. The samples collected from pads showed a sensitivity of 94.7% for detecting CIN2, which was comparable to clinician-collected samples (92.1%), the study found."
A sanitary pad fitted with a blood sample strip can detect human papillomavirus (HPV) from menstrual blood and may be used by women at home. Diagnostic comparison involved 3,068 women aged 20–54 in Hubei, China, each providing a pad-strip menstrual sample, a clinician-collected cervical sample, and an additional lab-processed sample. Pad samples demonstrated 94.7% sensitivity for detecting CIN2, comparable to 92.1% sensitivity from clinician-collected samples. Pad testing showed lower specificity, but negative predictive values and referral rates for further testing were similar. Minipad-collected menstrual blood offers a standardised, non-invasive alternative for HPV testing and cervical cancer screening.
