The Heat Pack

The click-to-heat sodium acetate pack warms your upper arm before collection. Warming causes local vasodilation, increasing superficial blood flow which means more reliable capillary filling, more efficient device performance, less hemolysis, and a more comfortable experience.

The Alcohol Wipe

The alcohol wipe reduces microbial load, removes oils and topical residues, and improves how well the Tasso+ adheres. That adhesion directly affects the vacuum seal the device relies on. Let the alcohol dry completely before collecting your sample. This helps prevent stinging, ensures the first microvolume of blood isn’t diluted, improves adhesion, and reduces the risk of contamination.

The Tasso+ and the Tube

Press the button for a virtually painless blood draw; gentle negative pressure draws blood into the attached lithium heparin tube. No manual pressure on the tissue means minimal interstitial-fluid dilution, less hemolysis, and a controlled anticoagulant ratio. After collection, cap the tube and gently invert it about ten times so the anticoagulant distributes fully.

Gauze and Bandage

Brief pressure with gauze helps stop any bleeding at the tiny puncture site, while the bandage protects the area from friction, sweat, and contamination as it heals.The small puncture site typically heals quickly.

The Bottom Line

Warm, clean, collect, cap, protect, ship. With validated assays and proper pre-analytical handling behind it, this carefully engineered sequence is how a home collection produces laboratory-quality results.
