Participants in clinical studies have reported lower levels of pain with this device compared to collecting blood with a finger stick or standard veinous blood draw.
Once delivered to the lab, it may take 3-5 business days for results to process.
Tasso’s innovative sample collection devices (available with Premium Sample Collection version) have made collecting a blood sample seamless, virtually painless & convenient with a comfortable experience being pivitol for the service.
Once your sample reaches the lab, results typically take about five business days to process. In the meantime, we’ll send you a link to schedule your 30-minute clinician visit. During this virtual appointment, a licensed clinician will review your lab results with you, discuss your symptoms and goals, and create a personalized treatment plan tailored to your unique needs.
The button sticks to the skin with a light adhesive. When the button is pressed, a vacuum forms and a lancet pricks the surface of the skin. The vacuum draws blood out of the capillaries and into a compatible container attached to the bottom of the device.
Some people refer to this devices as a needle-free system since it does not use a hollow venipuncture needle to enter a vein.
Each device is used one time to collect a sample and is then discarded.
