Nava Seewald

Are you Nava's lifesaving match? Order your swab kit and find out if you are her hero! 

Nava is a bright, bubbly 8-year-old who lights up every room she walks into. She loves gymnastics, art, singing, dancing, and spending time with her friends and family. Nava is kind, caring, and full of joy — but right now, she’s facing a big challenge.

Nava has been diagnosed with leukemia. Her family has learned that to defeat this cancer and recover her health, she needs a peripheral blood stem cell (PBSC) or marrow transplant.

That’s where you come in! You could be Nava's lifesaving hero without even knowing it. All it takes is a swab of your cheek to find out if you are a match for her or another patient in need. 

What you can do to help

  • Join the registry! Click on the blue "Join Registry" button. 
    • Donors in general good health between 18 and 35 years old may join the registry. Donors over the age of 35 can also join, but we ask that you to please donate $60 to offset the lab fees – Click here to learn why.  
    • Ninety percent of donors requested by transplant centers are 18 to 35 years old for medical reasons – Click here to learn why Age Matters.
    • Donors can remain in the registry until their 61st birthday – Click here to learn why the registry has an Age Limit.
    • Certain medical conditions may mean you are not able to join the registry or donate – Click here to check the Conditions List. If you're not sure, a health history questionnaire is part of the registration process.
  • Sponsor a swab kit. Click on the orange "Give to My Circle" button. Lab processing of every kit costs $60. Your contribution will help add new donors to the registry, who may be a match for Nava or another patient. 
  • Spread the word. Use the social media links to the right to share Nava's story in your Facebook and Twitter account. The more people who order a swab kit and join the registry, the faster she will find a donor.
