About this study

Official title: A Multi-site Clinical Evaluation of Capillary Blood Samples Collected Using the Tasso+SST Device for Downstream Analyte Testing.

This is a prospective, multi-center study within the U.S. Study participants will take part in two study visits a minimum of 14 days apart. During each visit, participants will self-collect capillary blood samples. Additionally, a healthcare provide will obtain capillary and venous serum samples. All capillary samples will be collected from the upper arm using the Tasso+ device paired with a commercially-available serum separator gel microtainer. The samples will be shipped to a clinical laboratory and tested for various analytes. Expected analyte values for each participant will be based on their venous sample results which will be compared to Tasso sample results

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number participants for which there is statistical concordance between serum biomarker results obtained from capillary blood vs. venous blood

    To establish the clinical performance of the Tasso+SST device for lay user self-collection and for trained healthcare provider (HCP) collection of capillary blood samples for downstream analyte testing at a clinical laboratory.

    Measured: 2 Weeks

Secondary outcomes (4)
  1. Number of lay users in a simulated home setting for with statistical concordance between serum biomarker results obtained from capillary blood vs. venous blood

    To evaluate the performance of Tasso+SST capillary samples collected by lay users in a simulated home environment

    Measured: 1 Day

  2. Number of observed device usability issues observed in lay users and HCP populations, i.e., deviations from the instructions for use.

    To demonstrate usability of the Tasso+SST device in naive lay users and in trained HCP populations

    Measured: 2 Weeks

  3. Number participants for which there is statistical concordance between serum biomarker results obtained from Tasso+ capillary blood by two different HCPs

    To demonstrate HCP inter-operator precision of Tasso+SST samples

    Measured: 2 weeks

  4. Number participants for which there is statistical concordance between serum biomarker results obtained from Tasso+ capillary blood by the same lay user

    To demonstrate lay user intra-operator precision of Tasso+SST samples

    Measured: 2 Weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Serum Analytes, run by Tasso Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number participants for which there is statistical concordance between serum biomarker results obtained from capillary blood vs. venous blood (time frame: 2 Weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2026.
