No, Guardant Reveal is not FDA approved at this time.
Guardant Reveal is a specialized blood test developed by Guardant Health. Its primary purpose is to detect circulating tumor DNA (ctDNA) in the bloodstream, which can indicate the presence of residual or recurrent colorectal cancer after surgery. While it offers valuable insights for clinicians and patients, the test has not received full approval from the U.S. Food and Drug Administration (FDA) for market use as a regulated in vitro diagnostic device.
Understanding Guardant Reveal
Guardant Reveal is a liquid biopsy test designed to monitor patients for colorectal cancer recurrence. It provides a non-invasive method to detect microscopic residual disease that may not be visible through imaging scans.
Key aspects of Guardant Reveal:
- Technology: Utilizes advanced genomic sequencing to identify specific DNA fragments shed by cancer cells into the bloodstream.
- Purpose: Primarily used for surveillance after curative-intent surgery for colorectal cancer to detect molecular residual disease (MRD) or early recurrence.
- Developer: Guardant Health, a leading precision oncology company focusing on liquid biopsy technologies.
- Availability: While not FDA-approved, tests like Guardant Reveal are often offered as Laboratory Developed Tests (LDTs), which are regulated by the Centers for Medicare & Medicaid Services (CMS) under the Clinical Laboratory Improvement Amendments (CLIA) to ensure laboratory quality and accuracy.

The Significance of FDA Approval for Medical Tests
FDA approval is a rigorous process that ensures a medical device or diagnostic test is both safe and effective for its intended use. For an in vitro diagnostic (IVD) test, FDA approval typically means:
- Clinical Validity: The test accurately measures what it's supposed to measure.
- Clinical Utility: The test results are useful for patient management decisions and lead to improved health outcomes.
- Manufacturing Quality: The test is consistently produced to high standards.
Medical tests that are not FDA-approved may still be available to patients as LDTs. While LDTs must comply with CLIA regulations, which focus on laboratory quality, they do not undergo the same extensive pre-market review by the FDA regarding clinical validity and utility as FDA-approved IVD products.
Current Status Overview
| Feature | Description |
|---|---|
| FDA Approval | Not FDA approved at this time. |
| Test Type | Liquid Biopsy, Laboratory Developed Test (LDT) |
| Purpose | Detection of circulating tumor DNA (ctDNA) for colorectal cancer recurrence. |
| Regulation Basis | CLIA (Clinical Laboratory Improvement Amendments) for laboratory operations. |
While Guardant Reveal plays a role in advanced cancer monitoring, its current status means it falls under a different regulatory pathway than fully FDA-approved diagnostics. Understanding this distinction is important for both healthcare providers and patients considering the test. You can learn more about how the FDA regulates laboratory-developed tests on the FDA's official website.
