Determining Menstrual Blood Loss from Feminine Hygiene Products

I need assistance with collecting female hygiene products to perform the alkaline hematin method to determine menstrual blood loss. Our study, if funded, would involve 20 women,10 with normal vaginal bleeding and 10 with heavy vaginal bleeding. The type of hygiene products used for extraction, their storage and shipping, and the costs of analysis are all required for this grant proposal.
