Wearable sensors assist ladies analyse menstrual blood for inexpensive, non-invasive well being monitoring.
Each month, round 1.8 billion folks menstruate, producing a largely ignored supply of well being info: menstrual blood. Like venous blood, which is routinely utilized in medical diagnostics, menstrual blood is wealthy in proteins and different biomarkers, but its use has been principally restricted to fertility and menstruation monitoring.
Recognising this untapped useful resource, Inge Herrmann and colleagues at ETH Zurich have developed a wearable sensor embedded into a normal sanitary pad that may accumulate and analyse key illness biomarkers.
The microfluidic platform, named “MenstruAI”, is a paper-based lateral movement assay with colorimetric take a look at zones. The take a look at zones home antibody-functionalized gold nanoparticles linked to completely different pathologies comparable to most cancers, endometriosis, or infections. When in touch with menstrual blood, these nanoparticles generate seen color adjustments that may be seen with the bare eye.
To simplify interpretation, the team also developed a smartphone app. The app guides the person by means of the method and analyses the outcomes utilizing machine studying skilled on lots of of take a look at strip pictures.
A significant benefit of MenstruAI is that, not like most blood sampling and evaluation strategies, it requires no pre- or post-processing. Because the authors spotlight, the platform was designed to be “accessible, inexpensive, reproducible, [and] non-invasive”. This makes it particularly related for settings the place ladies haven’t any entry to common medical check-ups and preventive testing is proscribed by financial constraints.
Following this profitable proof-of-concept, the crew hopes that their findings will encourage bigger subject trials to discover biomarker variability throughout people and assess real-world usability. Moreover, the platform might be prolonged to detect biomarkers for sexually transmitted ailments or different well being indicators.
Whereas the authors stress that MenstruAI shouldn’t be meant to exchange scientific diagnostics, it affords an inexpensive well being monitoring instrument that might operate as an early warning system.
By turning menstrual blood from “waste” right into a worthwhile well being useful resource, MenstruAI presents an inexpensive, barrier-free strategy to ladies’s well being monitoring that helps democratize healthcare.
