Lantern has a prescreening section that helps organise the information you've recorded — your notes, your questionnaire answers, and any measurements — into a form a clinician can review efficiently.

It's important to be precise about what this is, and what it isn't.

What prescreening is

  • A way to organise information. It gathers what you've already recorded and lays it out so a clinician can take it in quickly.
  • A prompt for a conversation. It helps make sure the things you've noticed are in front of the clinician, rather than lost in a short appointment.
  • Clinician-facing and early-stage. The prescreening tooling is designed to be read and acted on by a clinician, and it is at an early stage of development.

What prescreening is not

  • It is not a diagnosis. It never names a condition to you.
  • It is not a screen result. It does not give a "positive" or "negative," and it does not pass or fail you.
  • It is not a likelihood, risk, or probability. It does not tell you how likely anything is, and it shows no percentage or score.
  • It is not a decision. It does not decide anything about your care.

Who interprets what

The clinician interprets. Always. Prescreening organises your information; it does not draw conclusions from it for you. On your side, you only ever see your own information, organised — a calm summary to take to an appointment. Any provisional signal for a clinician to weigh is shown to the clinician, not to you, and the clinician decides whether to confirm, investigate, or set it aside.

An honest note on its stage

The prescreening tooling is experimental and early. Its underlying logic is a transparent, own-authored set of rules that has not been validated as a screening instrument, and it is not a cleared or approved medical device. It is not intended to drive a clinical decision on its own, and it stays behind an evaluation process before it could ever do so. We say this plainly because it matters.



How prescreening organises your information

Prescreening takes the information you've already recorded in Lantern and arranges it so a clinician can review it efficiently. Here's what it draws on, and how it stays honest.

What it draws on

  • Your own words — the notes and observations you've written.
  • Your questionnaire answers — the original question sets you chose to complete, kept verbatim.
  • Any measurements — the neutral measurements from check-in tasks you decided to record.

How it keeps things honest

  • Everything is traceable. Each piece of information carries a clear record of where it came from — what you recorded, when, in what setting, and whether you or a carer entered it. A clinician can follow any item back to its source.
  • Nothing is invented or interpreted. Prescreening organises what's there. It does not add conclusions, guesses shown to you, or meanings of its own.
  • No numbers that imply certainty. It shows no probability, percentage, risk figure, or score, because it has no validated basis to calculate one.

What happens with it

The organised information is prepared for a clinician to review. If the tooling surfaces anything for a clinician to weigh, that is shown to the clinician — with the reasoning laid out plainly so they can judge it — and the clinician decides whether to confirm, investigate, or set it aside. You are never handed a conclusion by the app.

Its stage, plainly

The logic that organises and surfaces information is a transparent, own-authored set of rules. It is a placeholder that has not been validated, and it is not a cleared or approved medical device. It is not designed to make a decision on its own, and it stays behind an evaluation process before it could inform real clinical decisions.


What you see vs. what a clinician sees

Prescreening deliberately shows two different views to two different audiences. This is a design choice, made for honesty.

What you see

A calm summary of your own information — your notes, your questionnaire answers, and any measurements, laid out clearly so you can bring them to an appointment.

You will not see:

  • A candidate condition or any named diagnosis.
  • A flag, tier, or "result."
  • A likelihood, probability, percentage, or risk figure.
  • A pass/fail, positive/negative, or normal/abnormal.

This isn't information being withheld from you for its own sake — it's that these things would imply a judgement the app is not able to make. What's yours to see is your own information, organised.

What a clinician sees

A clinician reviewing your record sees the same organised information, plus — where the tooling surfaces it — a provisional signal for them to weigh, clearly marked as experimental and not a validated screen. Crucially, it's explainable: every part of it can be traced back to the specific things you recorded, so the clinician can judge it rather than take it on trust. Their options are to confirm, investigate, or dismiss — the decision is theirs.

Why it's split this way

An app is not the right place to tell someone they might have a serious condition, or to reassure them that they don't. Both can be wrong, and both can cause harm. So Lantern gives you a clear record to talk through, and gives the clinician the material and the decision. The clinician interprets; the app organises.
