Research use only [RUO]

Laboratory research only. Not for human, veterinary or clinical use. No blanket legal exemption.

GlossaryUpdated 2026-09-24
01

Laboratory purpose

RUO describes a research purpose, not diagnosis, treatment or personal administration.

02

Conduct must match

Labels, marketing, buyers and actual sales practices matter together.

03

No legal exemption

The wording does not authorize an otherwise prohibited product or replace specific legal review.

The short answer

Research use only, or RUO, means a product is supplied for laboratory research rather than human, veterinary or clinical use.

An RUO label is not a legal exemption. The material, marketing, buyers and actual sales practices still matter.

What the designation means

The product's stated purpose is laboratory research, not diagnosis, treatment or personal administration. Labels and surrounding marketing should describe that purpose accurately.

A disclaimer is not the whole business

Regulators can assess intended use from advertising, website statements and the circumstances of sale. Research wording does not override human-use marketing or authorize an otherwise prohibited product.

Frequently asked questions

Does an RUO label protect me legally?

Not on its own. The label does not create a legal exemption. Marketing, product-specific requirements and actual sales practices need review.

Can RUO product be sold to individuals?

An individual's attestation alone does not establish that a sale is lawful or genuinely for research. Scale serves businesses and research buyers, not personal-use consumers.
