Symptom Checker (‘Triage’) - Instructions for Use

Last updated - 04 February, 2022 - ID/Version TR.IFU.2557_v1.0 (EN_UK).

This is an Instructions for Use manual for Babylon’s symptom checker, which is available as part of the Babylon app and on the website. The registered name for the symptom checker is Triage. This is what we call it in this manual.

This manual explains how to use Triage, who can and cannot use it, and what to do if you have a problem using it.

What is Triage?

Triage is a digital symptom assessment service. It is driven by a computer program, built with doctors. Users report symptoms and personal health information and answer related questions. The computer program suggests what level of care to get, and when to seek it. Sometimes, it also provides general self-care advice and a list of possible conditions.

What does Triage do?

Triage is designed to give general information about the level and timescale for seeking care. It is for non-emergency situations. It gives information for symptoms commonly seen in a primary care setting.

Who is Triage for?

Triage is intended to be used by lay users. The service provides information for people with symptoms that are common in primary care.

How to use Triage

1. Login

expand iconshrink icon

Log in to your Babylon account to start checking symptoms.

2. Select user

expand iconshrink icon

When you use Triage for the first time, it will ask you to choose whether you want to check your own symptoms, or someone else’s.

If you select someone else, you can set up a profile for them. You’ll need to add their sex at birth, and their date of birth.

Triage gives information for all ages. So you can use it on behalf of a child.

We’ll also ask if you want to share your data to help with public health research or clinical trials. We’ll remove your personal details such as your name and date of birth. This is completely optional.

Next time you open Triage, you will only need to select whether you’re using it for yourself or someone else.

3. Read disclaimer

expand iconshrink icon

Please read the disclaimer carefully before you use the Triage symptom checker. It contains important information about the service.

Once you have read the disclaimer, you can start checking symptoms.

4. Add your main symptom

expand iconshrink icon

Use the search box to search for a symptom. Or select one from the common symptoms on the screen.

A list of symptoms will appear in the box. Select the one that best matches your main symptom.

If you have more than one symptom, search for the one that’s bothering you most. You can only enter one symptom at this stage. You’ll be able to add more details later.

When you search for a symptom, make sure you enter words that describe what you’re experiencing (for example, fever or sneezing). Don’t enter words that describe a condition (for example, flu).

5. Answer questions

expand iconshrink icon

Answer the questions as they best describe your symptoms. Or answer on behalf of someone else.

Some questions are more complex. For these, you can find out more information by selecting the ‘?’ icon.

If you want to change any of your previous answers, select the ‘’ icon.

6. See results

  • Find your nearest care
  • Book an appointment

What do your results mean?

You may see your results at the end of the questions. Or you may need to select ‘View results’.

It’s important that you read the disclaimer. This is so you can understand your results.

Your results will include triage information. They may also include information on possible conditions.

Triage information

Triage information suggests what level of treatment your symptoms might need, and when.

It's based on the next steps that someone with your symptoms may take.

It’s important to talk to a healthcare professional if:

  • This is what your results recommend
  • You have any questions or concerns

You should also talk to a healthcare professional about non-serious conditions, even when the information says that people may manage these conditions at home.

Possible conditions

You may also see a list of possible conditions. This covers the types of conditions that people with similar symptoms to yours may have.

Triage does not give a medical diagnosis. Medical diagnosis usually needs a full assessment by a healthcare professional. This may include medical history, physical examination and tests.

The conditions are not listed in any particular order.

You should always speak to a healthcare professional if you have questions or concerns.

You can select a condition to find out more. This will give a short description and common treatments. It will explain why Triage listed the condition as a possible cause of your symptoms.

What are the limits for Triage?

Triage has the following limits to its intended outcomes:

  • Triage should not be used in place of talking to a healthcare professional
  • Triage does not give a medical diagnosis. Medical diagnosis usually needs a full assessment by a healthcare professional. This may include medical history, physical examination and tests
  • Sometimes, Triage gives information about how conditions may be treated. This is general information, not specific to the user or their medical concerns. It is not treatment advice. Users should not do or stop doing anything (such as taking medicines) based on this information
  • Healthcare professionals should not use Triage as a diagnostic or triage aid

Who cannot use Triage?

Triage must not be used in these situations:

  • In an emergency
  • For life-threatening symptoms such as (but not limited to):
    • Symptoms of a heart attack, including severe chest pain, which may spread to other parts of the body. The pain may be associated with sweating, shortness of breath or nausea
    • Symptoms of a stroke, including facial weakness, loss of arm movement or difficulty speaking
    • Severe breathing problems

Triage must not be used by:

  • Anyone under the age of 16. People over 16 can use it for children under 16
  • Anyone who does not have the capacity to decide on their own actions

Triage must not be used to check symptoms for:

  • People who are pregnant
  • Anyone whose gender identity does not match their sex at birth

This is because pregnancy and sex at birth can impact a range of health conditions that Triage is still learning about.

Triage must not be used outside of the region which the product version was designed for. These users should follow local or national guidelines.

Your supported region is in the Product specifications section of this manual.

What are the clinical benefits of Triage?

Clinical benefits of Triage include:

  • Providing triage information that is:
    • Safe and appropriate
    • Available in an average of less than 6 minutes
