Does making a professional-use assay available directly to consumers automatically make it a self-test?

Yes, in regulatory terms. If the device's intended purpose or labelling supports use by a lay person rather than exclusively by a trained professional, it falls under the Article 2(5) self-test definition and generally requires reclassification and additional usability evidence, not simply a repackaged instructions-for-use insert.

What extra evidence does a self-test typically require compared to the professional-use version?

Self-test devices attract heightened usability engineering scrutiny under IEC 62366-1 and Annex I Section 19 information-for-use requirements, and instructions must be understandable to a lay person at the education level of the intended user population, which usually means dedicated usability validation studies with representative lay users. This is in addition to, not a substitute for, the standard analytical and clinical performance evidence.

Do self-test devices usually end up in a higher IVDR risk class than equivalent professional-use devices?

In most cases, yes. IVDR classification rules generally place self-test devices in a higher risk class than the same analyte tested by a trained professional, reflecting the greater risk of misinterpretation or misuse without professional oversight. Manufacturers should confirm classification under Annex VIII rather than assuming parity with the professional-use version.

Self-Test and Near-Patient Testing (IVDR)

IVDR categories for devices intended for use by lay persons (self-test) or outside a laboratory environment by healthcare professionals (near-patient).

Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed July 25, 2026

Definition

Article 2(5) defines a device for self-testing as an IVD intended to be used by lay persons, including in home settings. Article 2(6) defines a device for near-patient testing as intended for testing performed outside a laboratory environment, generally near to or at the side of the patient, by a health professional. Classification rules and usability requirements differ, and Annex I Section 19 sets out specific information-for-use requirements.

What the regulation says

Regulation (EU) 2017/746 on in vitro diagnostic medical devices (IVDR), adopted on 5 April 2017 and applicable from 26 May 2022, distinguishes these devices by their intended users and settings. Article 2(5) defines self-testing devices as intended for use by lay persons, including in home settings. Article 2(6) defines near-patient testing devices as not intended for self-testing, but intended for testing outside a laboratory environment, generally near or beside the patient, by a health professional. These definitions guide MedTech manufacturers when establishing intended purpose and applicable requirements. Classification follows Annex VIII, including Rule 4. Self-testing devices are generally class C, with specified exceptions in class B, including pregnancy and fertility tests. Near-patient testing devices are classified in their own right under the applicable rules, rather than assigned a single class solely because of their setting. Annex I, Section 19 addresses design requirements for both categories, including intended users’ skills, foreseeable variations in technique and environment, and reducing handling and result-interpretation errors. The detailed labelling and instructions-for-use requirements are in Annex I, Section 20, including additional provisions for self-testing devices. Section 19 should therefore be read alongside Section 20.

What this means in practice

Self-test devices attract additional usability engineering scrutiny under IEC 62366-1 and, in most cases, a higher risk class than the equivalent professional-use device. Instructions for use must be understandable by a lay person with the education level of the intended user.

Examples

A rapid antigen test for COVID-19 purchased at a pharmacy for at-home use by an individual is a self-test device.
A blood glucose meter used by a nurse during a home visit to check a patient's sugar levels is a near-patient testing device.
A urine dipstick test kit used in a general practitioner's office to quickly screen for infections during a consultation is another example of near-patient testing.

Common pitfalls

•Assuming similar regulatory pathways for professional-use and self-test devices; self-tests generally face stricter scrutiny due to the lay user base.
•Underestimating the complexity of usability engineering for self-test devices, failing to meet the high standards required for lay person comprehension and safe use.
•Neglecting the specific information-for-use requirements in Annex I Section 19 of the IVDR, which mandates clear, understandable instructions for both categories but especially for self-tests.

Frequently asked questions

Article 2(5) defines a self-test as an IVD intended for use by lay persons, including in the home, while Article 2(6) defines near-patient testing as testing performed outside a laboratory environment, generally at or near the patient, by a health professional. The two categories carry different classification and usability expectations because the intended operator's competence differs.
