At-Home Blood Test for Preeclampsia Risk: A Breakthrough in Pregnancy Care

Preeclampsia, a potentially life-threatening condition during pregnancy, has long been a clinical challenge due to its unpredictable nature. Now, a revolutionary solution has arrived: an at-home blood test developed by Mirvie is transforming the way we predict and manage this condition.

This test, called Encompass, is a game-changer in personalized prenatal care, offering early detection months before symptoms develop. Let's explore how this innovation is reshaping maternal health.

💡 What Is Preeclampsia?

Preeclampsia is a hypertensive disorder that typically occurs after 20 weeks of pregnancy, affecting both maternal and fetal health. It is characterized by:

• Elevated blood pressure (≥140/90 mmHg)

• Proteinuria (protein in urine)

• Organ dysfunction (kidney, liver, brain)

• Fetal growth restriction in severe cases

Potential Complications:

• Eclampsia (seizures)

• Placental abruption

• Preterm delivery

• Maternal and neonatal mortality

🧪 The Science Behind the Encompass Test

Encompass by Mirvie is the first RNA-based blood test designed to predict preeclampsia before clinical signs emerge. Here’s how it works:

🔬 What It Analyzes:

• Gene expression profiles from the mother

• RNA signatures from the placenta

• Signals from the developing fetus

📆 When It's Done:

• Between 18 and 22 weeks of gestation

📈 How It Helps:

• Identifies biological markers and risk signatures

• Detects molecular changes months before symptoms

• Classifies risk levels using advanced machine learning algorithms

✅ Benefits of Early Detection

Detecting preeclampsia risk early allows for proactive interventions that significantly improve outcomes.

🩺 Clinical Actions Include:

• Low-dose aspirin (81 mg/day): Reduces risk by up to 60% when started before 16–20 weeks

• Frequent blood pressure monitoring

• Nutritional counseling

• Close fetal growth surveillance

👩‍⚕️ Benefits for Patients:

• Empowered decision-making

• Reduced emergency interventions

• Better birth outcomes

• Peace of mind for expectant parents

📊 Evidence-Based Results

Mirvie’s clinical trials have shown promising accuracy in identifying preeclampsia risks. The test boasts:

• High sensitivity for early-onset and late-onset preeclampsia

• Non-invasive sample collection at home

• Potential for scalable, accessible care globally

“By identifying women at risk early in their pregnancy, we can personalize prenatal care like never before,” says Mirvie's medical research team.

🏠 How to Take the Test at Home

The test is designed for convenience and safety. Here’s how it works:

1. Order the kit online via a healthcare provider

2. Collect a small blood sample using a finger prick

3. Mail the sample to the lab using prepaid packaging

4. Receive results securely within a few days

5. Discuss the personalized plan with your OB-GYN

🌍 A Step Toward Personalized Prenatal Medicine

This innovation marks a shift from reactive to preventive maternal healthcare. Rather than waiting for symptoms, clinicians and patients can now:

• Stratify risk early

• Tailor monitoring and treatment

• Reduce complications and hospitalizations

It’s a major stride in achieving equity in maternal health, especially for populations with limited access to prenatal diagnostics.
