At Home Self-Collection Safety Lab Panel

Self-Collection Safety Liver Panel

Improving the study participant and investigator experience while contributing to the success of decentralized clinical trials.

At Home Self-CollectionClinical trials are becoming increasingly decentralized, and Q2 Solutions is committed to discovering new and innovative ways to improve the participant and investigator experience.


Today, clinical study participants in the United States can collect a blood specimen for a safety lab test in the comfort of their own home using the Tasso+ device, eliminating the need to travel to an investigator site or have a healthcare professional visit their home.


The initial self-collection service is specifically a liver function panel designed to help diagnose and monitor liver disease or damage by measuring the levels of select enzymes, proteins, and compounds in the blood. The panel includes tests for ALT (alanine transaminase), AST (aspartate aminotransferase), ALP (alkaline phosphatase), total bilirubin, direct bilirubin, total protein, and albumin.

The process is simple:


  1. Self-collection kits are sent directly to participants from Tasso, Inc. The kit include a pre-labeled NanoCool™ Shuttle return shipper.
  2. Participant performs self-collection with the Tasso+ device.
    Watch video for more details on self-collection. 

  3. Participant prepares shipment in the pre-labeled NanoCool™ Shuttle return shipper and ships the specimen directly to Q2 Solutions clinical laboratory for testing.  
  4. Q2 Solutions performs laboratory testing and remotely sends laboratory reports directly to the investigator. 


Enhancing the participant and investigator experience

We are contributing to the success of decentralized clinical trials by reaching study participants where they live to perform remote safety laboratory tests. Our self-collection safety liver panel was designed with the study participant and trial investigator in mind. We aim to improve participant convenience and deliver a better experience, as well as support investigators by reducing their workload.


Enhancing the experience of participants by reducing their burden has secondary advantages as well.  Because it is more convenient for participants to collect their own specimens, self-collection has the potential to increase trial enrollment by broadening access to a larger number of participants and perhaps even a more diverse pool.

Frequently Asked Questions

What is the Tasso+ device?

A liquid blood collection device that allows for volumes 300-600 µL



Where does collection take place?
Collection can be performed at home or at the investigator site.
How does the collection process work?

The participant places the device on his/her shoulder (after cleansing the area with an alcohol pad) and presses the red button to start the blood collection. A lancet is released and pricks the skin, a vacuum is created, and capillary blood is collected into the attached SST tube. See video for more details.

How long does it take to receive a kit?
Orders are processed and shipped within one business day.  Delivery times are dependent upon courier services and participant location.
What is the volume required?
The minimum volume required is 200 µL of whole blood and the Tasso+ device enables ~600 µL whole blood in five minutes.
Is refrigerated shipping required?
Yes. A NanoCool™ Shuttle will be provided to the patient, which is activated by simply pressing a button. The shuttle will keep the sample between 2-8°C for 42 hours.
