FDA clearance and FDA approval are different regulatory decisions for laboratory tests—not interchangeable labels or guarantees that a test is right for every patient. In the United States, “cleared” usually refers to a 510(k) decision based on substantial equivalence to a legally marketed predicate; “approved” usually refers to a PMA decision based on an independent demonstration of safety and effectiveness. Other tests may be classified through De Novo or authorized for emergency use, while some laboratory-developed tests (LDTs) are offered without FDA premarket review. The meaning for a particular test depends on its exact intended use, claims, specimen, and labeling.
For patients, clinicians, and anyone reading a test report, the practical question is not simply whether a product has an FDA-related label. It is what decision FDA made, what specific test and use that decision covers, and whether those conditions match the test being considered. A status attached to one assay, specimen type, or intended use should not be assumed to cover every test from the same company or every use of a testing platform.
What does “FDA cleared” mean for a laboratory test?
“FDA cleared” generally means FDA granted a 510(k) submission after determining that the device is substantially equivalent to a legally marketed predicate that is not subject to premarket approval. FDA describes this as a comparative review, not the same standard used for PMA approval.
A 510(k) submission is intended to show that the device to be marketed is at least as safe and effective as its predicate for the relevant intended use. For an in vitro diagnostic (IVD)—a test performed on samples such as blood or tissue—FDA evaluates relevant analytical performance in relation to that predicate. The predicate is a legally marketed device used as the comparison point; it is not necessarily the first test of its kind.

Substantial equivalence is not a declaration that the new test is identical to the predicate. Nor does clearance mean that every possible application, patient group, sample, or claim is covered. The relevant FDA record and labeling define the scope. A useful starting point is FDA’s explanation of the 510(k) clearance process and its overview of IVD regulation.
What does “FDA approved” mean for a laboratory test?
“FDA approved” usually means FDA authorized a device through the premarket approval (PMA) pathway. PMA is generally for Class III devices, and FDA’s standard is an independent demonstration of safety and effectiveness—not substantial equivalence to a predicate.
That distinction matters for diagnostic tests because a result can affect a person’s care. A false negative or false positive may lead to different decisions, so the test’s evidence and the population and use it is intended for matter. Approval does not mean that a test is infallible, appropriate for every person, or validated for uses beyond its approved labeling. Read the specific indication and instructions rather than treating “approved” as a universal endorsement.
FDA describes PMA as a scientific and regulatory review. Its PMA overview explains the pathway; the IVD regulation overview places it alongside other diagnostic-device routes.

How do clearance and approval differ from De Novo and EUA?
De Novo classification and Emergency Use Authorization (EUA) are separate routes, not alternate names for clearance or approval. Each has its own criteria and limits.
- De Novo: A risk-based route for certain novel devices with no legally marketed predicate. FDA may classify a qualifying device when general controls alone, or general and special controls, can provide reasonable assurance of safety and effectiveness for its intended use. A De Novo-classified device may later serve as a predicate for a 510(k) submission.
- EUA: An emergency access mechanism available under specified emergency circumstances and criteria. FDA notes that an EUA may be based on less data than would be required for PMA, 510(k), or De Novo. Use must remain within the authorization letter and manufacturer instructions, including limitations on specimens and use.
Neither status should be casually translated into “FDA approved.” For an EUA test, check the current authorization terms and instructions, rather than assuming ordinary premarket review took place. FDA’s information for laboratories implementing IVD tests under EUA explains the importance of following those conditions.
What should I check in the FDA record for a specific test?
Look up the exact product and intended use; a company’s general claim that it has an FDA-cleared or approved product does not establish that every assay, sample, or claim is covered. FDA directs readers to its device databases, including 510(k), PMA, and De Novo records, and to the EUA list when relevant.

- Identify the precise test. Record the product or assay name, manufacturer, and, when available, product code. A product code can help locate a device in FDA databases.
- Find the applicable record. Search the relevant 510(k), PMA, or De Novo database; check the EUA list if the test is described as authorized for emergency use. Do not treat a company’s broad description of a platform as the record for a particular test.
- Read the intended use and indications. Confirm what the test claims to detect or measure and the purpose for which FDA reviewed or authorized it.
- Compare the specimen and population. Check which sample types and tested populations are covered. A record for one specimen or population does not, by itself, establish coverage of another.
- Read the instructions and any authorization limits. For an EUA, follow the authorization letter and manufacturer instructions. For other pathways, use the relevant labeling to understand the test’s stated scope.
This is more useful than asking only whether “the company” or “the lab” is FDA-cleared. A device status is tied to the particular product and claims in its record. If a test is being considered for a use not described there, ask the ordering clinician or laboratory how that use is supported.

How should patients interpret test performance claims?
FDA’s consumer-test guidance distinguishes analytical validity from clinical validity. Analytical validity concerns whether the test accurately and reliably measures what it claims to measure; clinical validity concerns whether that measurement predicts or indicates a health state. A test can measure something reliably without that measurement answering every clinical question a patient might have.
For consumer-facing tests, FDA also considers the claims made, whether sample-collection instructions can be understood without a healthcare provider, and whether result reports are understandable. These are practical questions for patients to raise before relying on a report: What exactly does this result measure? What does it predict? What limitations apply to the sample or the intended population? What should happen next if the result is unexpected?
A status alone cannot interpret an individual result or tell a patient what action to take. Discuss the result and its clinical meaning with a qualified clinician; for a genetic test, a genetic counselor may also help explain what the result does—and does not—say. FDA’s guidance on direct-to-consumer tests describes these performance and communication considerations.

What are laboratory-developed tests, and what is their current FDA status?
FDA describes an LDT as an IVD intended for clinical use and designed, manufactured, and used within a single qualifying clinical laboratory certified under CLIA and meeting CLIA high-complexity requirements. The regulatory position around LDTs changed in 2025, so older descriptions of a phaseout schedule should not be treated as current deadlines.

A federal district court vacated FDA’s May 2024 LDT final rule on March 31, 2025. On September 19, 2025, FDA issued a final rule reverting the regulatory text to the version in place before the 2024 rule. As of the research current date, November 13, 2026, the stage dates previously announced under the 2024 rule are not operative current deadlines. FDA’s LDT page reports this federal regulatory history.
This change in federal rules does not determine whether any particular laboratory test is analytically or clinically sound. FDA says it generally does not review some LDTs created and performed in one laboratory when offered only on prescription. Such tests typically do not have FDA’s independent assurance of analytical validity, clinical validity, or clear communication of results. The qualification matters: this description should not be generalized to every laboratory test or used to conclude that a specific test is inaccurate.
CLIA certification of a laboratory is not the same thing as FDA approval of an individual test. A laboratory’s certification and a test’s regulatory status answer different questions; patients should ask the ordering clinician or laboratory what evidence supports the test and how its limitations affect interpretation. FDA’s definitions and general oversight FAQs provide FDA’s LDT description and discussion of the scope of its oversight.

- Clearance: Ask what predicate and intended use the 510(k) record addresses. Do not infer a PMA-style independent demonstration from the word “cleared.”
- Approval: Confirm the PMA indication and labeling. Do not assume approval covers a different use or that results are error-free.
- De Novo: Confirm the classified device and intended use. Its lack of a predicate is part of why this pathway exists, not evidence that it has no regulatory review.
- EUA: Check authorization terms, specimen limits, and instructions. Emergency authorization has criteria and conditions distinct from ordinary premarket pathways.
- LDT: Ask what the lab’s test is intended to do and what validation or evidence supports it. The absence of FDA review does not by itself prove inaccuracy, and CLIA status does not equal FDA clearance or approval.
The most reliable interpretation is specific: identify the exact test, match its record to the specimen and intended use, and then discuss what the result means for the person being tested. For the current LDT framework in particular, consult FDA’s current page rather than relying on older summaries of the vacated rule.
Frequently Asked Questions
Does FDA clearance mean a test is 100% accurate?
No regulatory label should be read as a promise that every result will be correct. Ask what the test measures, what performance evidence applies to its intended use, and how the result should be interpreted alongside clinical information.
What is a predicate device in a 510(k) review?
It is a legally marketed device used as the comparison point for FDA’s substantial-equivalence determination. The predicate helps define the basis of the review, but it does not mean the new test is identical to it.
Recommended Free Tools
Can an FDA-cleared test be used on a different kind of sample?
Do not assume so. Check the specific record and labeling for the specimen types covered, and ask the laboratory or clinician how a different sample type is supported before relying on the result.
Where can I find the latest information about LDT rules?
FDA’s Laboratory Developed Tests page is the most direct source for the agency’s current framework and updates. Because the federal policy changed after the 2024 rule, older articles may describe deadlines that are no longer operative.
