In response to our recent post, so many of you shared your experiences with blood clotting disorder testing — also called thrombophilia testing — and no two stories were the same.

➡️ One person learned she had a prothrombin gene mutation after five miscarriages and was later diagnosed with antiphospholipid syndrome.

➡️ Another experienced a clot during military training that was initially dismissed as a muscle strain. Testing later showed she is positive for factor V Leiden.

➡️ Some learned about their inherited risk after multiple pulmonary emboli and now worry about whether their children could have inherited the same condition.

➡️ Others have faced repeated clots without a clear answer despite extensive testing.

These stories show just how complex thrombophilia testing can be and why communication, timing, and access to care are so important.

Join us for our next PEP Talk, Thrombophilia Testing While on Blood Thinners, on Tuesday, November 11 at 7 p.m. ET to learn more about who should get tested, when, and why. Plus, your rights and options if you’re interested in testing that isn’t routinely recommended.

Thinking about thrombophilia testing while taking

Thinking about thrombophilia testing while taking a blood thinner? You’re not alone. It’s one of the most common questions patients ask.

Join us for our next PEP Talk to learn what thrombophilia testing really means and how timing, medication, and results can shape your care. Our medical expert, Dr. Dana Angelini, will cover:

✅ Who might be tested: Factors your healthcare provider may consider
✅ When testing is done: Certain blood thinners can affect results, so timing matters
✅ Why testing is ordered: To understand inherited risks and guide prevention or treatment decisions
✅ How results may impact care: From medication choices to long-term management plans

We’ll also discuss how to protect yourself and your family if you’ve tested positive, what to know about your rights and options if you’re interested in testing that isn’t routinely recommended, and hear from patients about their experiences.

Understanding thrombophilia testing isn’t just about lab work — it’s about making informed choices for your long-term care and peace of mind.

🩸 Thinking about thrombophilia testing while on

🩸 Thinking about thrombophilia testing while on a blood thinner? It’s not always straightforward.

Testing can offer valuable insights into long-term clotting risk, help identify inherited conditions that may affect family members, and guide future care decisions, such as how long to stay on anticoagulation or how to manage pregnancy or surgery.

But timing matters. Results are often less accurate while on blood thinners, and for many people, testing won’t change their treatment plan. It can also cause unnecessary worry or add unexpected costs.

We hope you’ll join us for our November PEP Talk to learn when thrombophilia testing is useful and when it may not be.

“I’m a 63-year-old man and have experienced tw

“I’m a 63-year-old man and have experienced two instances of blood clots (deep vein thrombosis, or DVTs) in my left calf. The first happened in 2018, shortly after being diagnosed with stage one lung cancer. I had surgery to remove the lower part of my left lung and followed regular scans for five years before being declared cancer-free.

For a while, I was in great shape and exercised regularly. But over the past few years, life got busy — I was working a lot, earning my master’s degree in Information Systems Management, and teaching my first class on Microsoft Apps. During that time, I gained about 50 pounds.

Earlier this year, I started swimming again, about 1.5 miles three times a week, to safely lose weight. I had dropped 10 pounds when I noticed pain in my calf. I assumed it was a muscle strain from swimming, but the swelling got worse. I was admitted to the hospital and treated for another DVT. I spent four days on a blood thinner while doctors monitored me for potential clots in my heart or lungs.

A CT scan showed some enlarged lymph nodes in my chest, so I followed up with both oncology and cardiology. Thankfully, my PET scan came back negative, and a later scan showed the lymph nodes were normal, so I canceled the biopsy. I’ll continue to get yearly CT scans because of mild emphysema and a small lung nodule my doctors are watching.

Now, I’m back to exercising and focusing on my health again. I still have some swelling in my lower leg, but it’s improving. I have a cardiac angiogram scheduled soon, and I’m continuing on apixaban permanently. I actually discovered this group while watching a YouTube video about blood clots, and I’m grateful to have found a community that understands what this journey is like.”

🎃 This Halloween, here are five truly frightening facts about blood clots. They’re more common and deadly than most people realize:

1️⃣ 900,000 Americans are diagnosed every year

2️⃣ Blood clots kill more than HIV, breast cancer and car accidents combined

3️⃣ Fewer than 6% of Americans know what blood clots are

4️⃣ One person dies of a blood clot every six minutes in the U.S.

5️⃣ Blood clots kill 100,000 people in the U.S. every year

Knowledge saves lives. Don’t just share ghost stories today, share awareness. 🩸

💪🩸 "Two weeks after a 68-mile bike ride, I couldn’t straighten my leg, and my veins bulged.

The ER dismissed it as a bruise. I explained that it wasn’t a bruise, that I’d already seen multiple professionals, and that the pain was worsening. My vitals looked fine, but I told the doctor I was on estrogen-based birth control and needed a scan.

He ordered one and when the diagnosis came, I cried. The next day, the hospital called to check on me. I mentioned recent shortness of breath and they told me to return right away. That’s when they found a bilateral pulmonary embolism.

The diagnosis and blood thinners felt like a death sentence. I didn’t know how long I’d be on medication or if I’d ever get back to what I loved most: ski mountaineering, climbing, and ultramarathon running—the moments where body, mind, and mountain align.

I had a mix of risk factors: a healing leg injury, estrogen-based pills, the Factor V Leiden mutation, dehydration, and long hours of repetitive cycling.

I read everything I could about blood clots and returning to endurance sports. There’s a major gap in research about young, athletic people with clots. NBCA was incredibly supportive, as were survivors in the climbing community.

Still, I had many questions about high altitude and ultramarathon running after clots. Over time, I connected with other active survivors and met a high-altitude pulmonologist who gave me hope.

With help from a therapist, I began to trust my body again and manage my fear of recurrence. I listened closely to what my body was telling me. I started with hiking, then trail running, then mountain sports.

After three months, I was off blood thinners and entered the gray zone. What could my body do now? What couldn’t it? There was only one way to find out.

I set a big goal: skiing Denali, the tallest mountain in North America. Gradually, I got stronger. I made it to 14,000 feet on Denali before turning around due to weather—and I learned to love my body again."

🚗 As thousands head to New York City for the @nycmarathon on Sunday, one mother’s message is lighting up highways across the state: pause the ride, take a stride.

After losing her 19-year-old son, Paul Jr., to a pulmonary embolism in 2013, Denise Englert of Clarence Center, NY, turned her grief into action. Partnering with Lamar Advertising, she helped secure donated digital billboards that remind travelers to move their legs, stretch, and take breaks to prevent dangerous blood clots.

Whether you’re driving long hours or flying in for race weekend, extended travel can raise your risk for deep vein thrombosis (DVT), especially if you’ve had a blood clot before. Stay safe on your trip to NYC with these simple tips:

🔹 Get up and move every hour

🔹 Do gentle leg and foot stretches while seated

🔹 Stay hydrated and limit caffeine and alcohol

🔹 Avoid crossing your legs

🔹 Wear loose clothing and a medical ID if you take an anticoagulant

🔹 Know the signs of a blood clot and seek care if symptoms appear

Thanks to Denise’s advocacy, travelers across New York are seeing these lifesaving reminders on the road, a powerful tribute to her son and a message that could save lives.

🩺 The road to thrombophilia testing isn’t the same for everyone.

In a 2022 NBCA webinar, Dr. Caroline Cromwell and Dr. Peter Kouides — both members of our Medical and Scientific Advisory Board — and a thrombophilia patient discussed how experiences can vary widely, from the decision to test, to the challenges of timing, to understanding what results mean.

As we prepare for our November PEP Talk, Thrombophilia Testing While on Blood Thinners (Tuesday, Nov. 11 at 7 p.m. ET), this conversation is a reminder of why patient education and communication matter so much.

🌻 In loving memory of Kelley Syron 🌻

On a sunny morning in Palm City, FL, friends and family came together for the annual walk honoring Kelley Syron — a vibrant, compassionate young woman whose life was tragically cut short at age 34 by a pulmonary embolism following a routine surgery.

Kelley dedicated her career to helping children and families through her work at The Children’s Therapy Center, where she was known for her kindness, empathy, and unwavering commitment to others. Her legacy of care and compassion continues to inspire everyone who knew her.

This year’s walk, organized by her mother Suzan Syron-Singh, brought together twice as many participants as last year and raised more than $6,100 for the National Blood Clot Alliance! Participants wore yellow shirts with sunflowers — Kelley’s signature flower — symbolizing her warmth, optimism, and the light she continues to bring to others.

In Florida, where Kelley’s family and friends continue to honor her memory, the passage of the Emily Adkins Family Protection Act this summer represents hope and progress.

Like Kelley, Emily died of a preventable blood clot after a routine procedure. This landmark law will help hospitals and clinicians better identify, prevent, and report dangerous blood clots so more families don’t have to experience the same loss.

Thank you to Suzan and everyone who helped make this beautiful event possible, celebrating Kelley’s memory and helping raise awareness about life-threatening blood clots. 💛
