Developing diagnostics for women.

Rea is developing a self-test to help assess the risk of preterm birth in symptomatic pregnant women from week 22.^*

Our approach

§01 · The problem

Preterm birth is the leading cause of death in children under five.

Every year, one million babies die from complications of preterm birth. Behind each of those numbers is a family that didn't know in time. Those who survive carry consequences that often last a lifetime.

According to the World Health Organization, 75% of these deaths are preventable — if the risk is identified early enough for clinicians to act.

Today, it rarely is. For many women presenting with symptoms, that means no rapid test at all.

§02 · Our work

We are developing an at-home self-test for preterm birth risk.

Rea Diagnostics is building a simple, self-collected test that a woman can use at home — without a clinician, without a clinic visit, and without specialized equipment.

The test is designed to indicate whether she is at elevated risk of preterm delivery, to inform the next clinical conversation with her doctor.

The principle

i. A self-collected vaginal swab, taken at home.
ii. A paper-strip immunoassay. No reader, no electronics.
iii. A result in minutes — to inform the next clinical conversation.
