Why we do this

Bringing molecular testing closer to where care happens.

Molecular testing is typically performed in central laboratories, which makes it harder to act on results during the same visit. AscellaOne is a compact platform designed to make nucleic acid testing practical close to the point of care.

Core technology

Four technology building blocks.

Isothermal amplification

A single reaction temperature with no thermal cycling, suited to compact instruments.

Freeze-dried reagents

Reagent formulations designed for storage and distribution without a cold chain.

Handheld reader + app

A compact reader operated through a smartphone or tablet app.

Rapid assay design

A proprietary primer design pipeline to add new targets efficiently.

Intended settings

Designed with healthcare settings in mind.

Clinics

Clinics

Primary care and outpatient settings.

Hospital wards

Hospital wards

Wards, ICUs and emergency departments.

Long-term care

Long-term care

Care facilities, with testing performed by healthcare professionals.

Field response
