Study teams, physicians and patients order kits through our APIs. Every order names the receiver, the address and the panels.
The most overlooked sample in medicine.
Menstrual blood. We built everything it takes to use it in diagnostics: collection, logistics, lab software and science, in one regulated system.
The Q-Pad · Simple and comfortable
Wear it like any pad. Mail back a lab-grade sample.
The Q-Pad collects menstrual blood on a removable Q-Strip while it is worn. The Q-Strip dries into a stable sample that goes back to the lab by ordinary mail.
Why menstrual blood
An information-rich sample, delivered every month.
Systemic blood
Whole blood from the body’s circulation, with its cells, proteins, hormones and metabolites. For validated analytes such as HbA1c and several hormones, levels track closely with a venous blood draw, without the needle.
Vaginal fluid
Vaginal fluid, and the microbes and viral DNA it carries, picked up as the blood leaves the body. It makes it possible to look for high-risk HPV and sexually transmitted infections, without a speculum or a swab.
Endometrial tissue
The shed lining of the uterus: endometrial cells, tissue fragments, immune cells and the molecules they release. Collected every month, it offers a repeatable view of tissue that otherwise takes a biopsy to reach.
