Every month, the body delivers a sample no needle can reach.
Menstrual blood is three samples in one: systemic blood, vaginal fluid and tissue from the lining of the uterus. A new sample type with unique access, not a replacement for every test.
Where each part comes from: the uterine lining, the circulation, and the cervix and vagina.
Three samples in one
01
Systemic blood
For validated analytes, menstrual blood reads like a venous draw, without the needle. HbA1c monitoring is FDA cleared.
r = 0.949HbA1c, menstrual versus venous, in 172 women. BMJ SRH 2022 →
r = 0.91–0.96HbA1c, TSH, AMH, FSH and LH in 152 women. F&S Reports 2024 →
