Diagnostic

The diagnostic icon represents a diagnostic tool or analysis feature. This icon is often used to indicate that a diagnostic test or analysis is being performed.

In software and technology, diagnostic tools are used to identify and troubleshoot issues or errors. For example, in computer systems, diagnostic tools can be used to analyze system performance, detect errors, or troubleshoot connectivity issues. Similarly, in medical devices, diagnostic tools can be used to analyze patient data, detect health issues, or monitor treatment progress.

From a UX perspective, the diagnostic icon communicates the presence of a diagnostic tool or analysis feature. It helps users understand that they can use the tool to analyze data, detect issues, or troubleshoot problems.

Diagnostic is one of 1,735 icons in Fluent UI MDL2, made by Microsoft Corporation and released under MIT. It is drawn on a 2048 × 2048 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds DiagnosticIcon to components/icons/fluent-mdl2-diagnostic.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed DiagnosticIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Diagnostic icon, or any of 1,735 Fluent UI MDL2 icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 2048 × 2048 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Diagnostic", so screen readers say what it does.

Yes. DiagnosticIcon passes every SVG prop to the svg element, so <DiagnosticIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Fluent UI MDL2, Microsoft Corporation and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are error, analysis, report, issue, troubleshooting and diagnostic. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Diagnostic in another set.

Fluent UI MDL2 draws many icons in several styles: Solid next to the default. Open the library and pick a style above the grid to see Diagnostic's siblings in it.
