How it works

Four steps.
A few minutes.

No clinic visit, no waiting for a callback. Just a fingerstick, a drop of blood, and the phone that's already in your hand.

01

Prick finger

Use the Thyra lancet device for a small, single-drop fingerstick sample.

Apply blood

Place one drop onto the cassette's sample well — no measuring, no mixing.

Clip-on light

A small ring-shaped light clips around your phone's camera to read the cassette's fluorescence.
