Weavr Health

Weavr Health, formerly Boston Microfluidics, is a private medical device company focused on blood collection beyond the point of care, including self-collection in patients' homes. The company develops microfluidic, needle-free or simplified blood collection and sample processing devices intended to make laboratory-quality testing more accessible without requiring a phlebotomist. Publicly described products include Velvet, an at-home blood collection device, and Silk, a COVID-19 rapid antibody test. The company serves diagnostic testing workflows rather than developing therapeutics, positioning it closer to diagnostics and sample-collection hardware than to a traditional drug-development biotech. Its core value proposition is enabling consumer-driven, remote sampling for healthcare providers, labs, and telehealth-enabled care models.
