We are currently seeking patients with scleroderma to donate a small sample of blood from the comfort of their own home.

The goal of this study is to identify biomarkers in the blood of scleroderma patients that may be used to develop better diagnostics and treatments for scleroderma .

The Moral Behind Our Story

We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We believe it should be easy for patients to contribute to the advancement of research for medical conditions that matter most to them, regardless of their location or ability to travel.

Our mobile staff covers the US, Canada and parts of Europe. Each staff member is trained on study specific protocols and carries the credentials necessary to conduct clinical trial procedures in the patient’s home.

The Key to Success is Swiftness

Once you sign up, we will review your health profile and contact you if you might qualify for a research study. If you may qualify for a study, a clinical research coordinator will contact you within 48 hours to confirm your health information and tell you more about what is required to participate in a certain study.

When you are ready to be scheduled, your clinical research coordinator will work with you to schedule an at­-home visit. One of Sanguine’s mobile health staff members will meet you in the privacy and comfort of your home to explain the research study and perform the blood collection.
