Test Tubes Icon

Q: When should I use it instead of a similar icon?

Use it for lab results in a patient portal, listing blood work and panels by collection date; sample tracking rows in a lab or biobank tool, 1 row per tube with its status and location; and blood and urine test bookings in a clinic flow, chosen before the visit is confirmed. For experimental features on a Labs page, or the test runner panel of a code editor, use the Flask icon. For case counts and positivity rates on a public health dashboard, use the Virus icon.

Two upright test tubes side by side with different liquid levels, for lab tests, samples and research. Available in 4 styles (outline, solid, duotone and filled) as a React component you install with the shadcn CLI.

Test Tubes icon FAQ

What does this icon show?

Two upright test tubes side by side with different liquid levels, for lab tests, samples and research. Typical uses: lab test results panel, clinical sample tracker and medical research section.

When should I use it instead of a similar icon?

Use it for:

Lab results in a patient portal, listing blood work and panels by collection date
Sample tracking rows in a lab or biobank tool, 1 row per tube with its status and location
Blood and urine test bookings in a clinic flow, chosen before the visit is confirmed

For experimental features on a Labs page, or the test runner panel of a code editor, use the Flask icon. For case counts and positivity rates on a public health dashboard, use the Virus icon.

Which styles does it come in?

4 styles: Outline, Solid, Duotone and Filled. Every style is drawn on the same 24 by 24 grid and installs as its own file, so you can switch styles without touching the layout.

How do I install it with the shadcn CLI?

Copy the install command from the panel above, in the style you want, and run it in your project. The shadcn CLI adds the icon as a React component that you import and render like any other. It draws in the current text color, so your text color and size classes style it. Icon installs need a ReUI Ultimate license.

What icons go well with it?

Capsule and Syringe sit beside it in the same toolbar or menu. More from the same family and the Health set: Bandage, First Aid Kit, Flask and Mask.

When was it added?

It joined the ReUI icon library on June 30, 2026.
