I cannot speak on behalf of all women, but I can speak on behalf of my own personal experience...it was less invasive than putting on my eyeliner, and I would certainly think it would be much less invasive than sticking my finger with a needle, getting a blood draw, having my breast compressed between two metal sheets of machine, losing a breast, going through breast reconstruction, enduring months of chemotherapy, and enduring the tragedy of losing my life....:)
The sample strip is a thin piece of filter paper that is commonly used to test for dry eye. Typically, once the strip begins to get wet, the slight irritation goes away. In a survey conducted with over 400 individuals, the average reported pain score after using the sample strip was 1.4 out of 10, with 0 being no pain/discomfort and 10 being intense pain/discomfort.
