Each TruAge test kit comes with detailed instructions, as well as all necessary medical tools needed to safely and comfortably complete an at-home blood collection sample. Several lancets (a small finger-pricking tool) are included in each TruAge kit. However, patients who are squeamish or uncomfortable with that extraction option can purchase a Tasso+ device, which attaches to the bicep-facing, upper section of the arm for minimal patient involvement in the blood collection process.
