Finding kidney disease sooner in communities most at risk

Chronic kidney disease (CKD) is a common condition that can develop silently over time. People of Black African or Caribbean heritage face a higher risk of kidney problems, but early signs are often missed because symptoms usually do not appear until later stages. This study, run by researchers at King's College Hospital, is testing a new way to reach people. Trained community workers offer simple, friendly kidney checks at local faith centres and neighbourhood venues. Participants can choose from three simple tests: a quick urine check on the day, a home urine kit using a smartphone app, or a tiny finger-prick blood test. You can even take part without giving your name. If your results show potential kidney strain, the team will guide you on how to follow up with your GP to protect your long-term health.

Chronic Kidney Disease

What is this study about?

Our kidneys do the vital job of filtering waste and extra fluid from our blood. When kidney damage happens slowly over time, doctors call it chronic kidney disease. In the early stages, most people feel completely well. Unfortunately, people from Black African and Caribbean backgrounds are more likely to develop kidney problems and are at higher risk of developing kidney failure. Catching kidney strain early is crucial because simple lifestyle changes and everyday medications can protect your kidneys and keep you healthy for longer.

The HIDDEN CKD study aims to bring health checks directly to the heart of the community. Rather than asking people to visit a hospital or clinic, researchers have teamed up with local community groups, including the Africa Advocacy Foundation. Together, they are setting up friendly health check events in familiar places such as churches, mosques, and community halls.

At these events, trained community educators provide information, answer questions, and offer fast, painless testing options. By seeing how well these community events work, the study hopes to create a blueprint for the NHS to reach people who might otherwise miss out on early health checks.

Key takeaways

Offers free, quick kidney health checks in local community spaces.
Aimed at adults aged 18 and over, focusing on people of African heritage.
Tests include simple urine checks and a quick finger-prick blood test.
You can take part anonymously without giving your name.
Helps spot kidney problems early when they are easiest to manage.

Who may be eligible?

This study is open to adults aged 18 and over who would like a free, simple check of their kidney health. It is particularly designed for people of African ancestry, who are known to have a higher risk of kidney disease, but community members wanting to check their kidneys are welcomed.

You do not need to have any known health problems or symptoms to take part. The events are designed to be easy to access and informal.

You cannot take part if you are unable to carry out the basic testing steps or if you are unable to give your own informed consent to participate.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

I am aged 18 or older.
I would like to check my kidney health.
I am able to attend a community health check event.
I am able to give informed consent to be tested.

Answer every question to see your result.

What does participation involve?

Taking part involves visiting a local community event. You will meet trained peer educators who will talk you through your options. You can choose one or more simple tests: a quick urine test done on the spot, a take-home urine test that uses a free smartphone app, or a simple finger-prick blood test to check how well your kidneys filter waste.

You can remain completely anonymous if you wish. You will also be invited to fill out a short, anonymous feedback form to share your thoughts about the event. There are no study medications to take.

If you choose to leave your contact details and a test suggests possible kidney strain, a member of the research team will call or email you 4 to 6 weeks later to see how you are doing and advise you to see your GP. A small group of participants will also be invited to take part in a short 30-minute chat about their experience to help improve future events.

Potential risks and benefits

The main benefit of joining is finding out about your kidney health and learning how to protect it. If early kidney changes are found, you can take action with your GP to prevent further damage. The physical risks are very low: the finger-prick test may cause brief discomfort or a small bruise. Some people might feel anxious if their test suggests a potential problem, but the team will provide clear, reassuring guidance. Your participation is entirely voluntary, and you can change your mind and stop at any time.

Common questions

Do I have to give my name and contact details to get tested?

No. You can have your kidney health check completely anonymously if you prefer.

Does the finger-prick test hurt?

It feels like a tiny pinprick and only takes a few seconds. It might cause mild, temporary soreness or a small bruise.

What happens if my test shows an unusual result?

The team will explain what the result means in plain English and advise you to book an appointment with your GP for formal follow-up tests.

Do I need to take any new medicines as part of this study?

No. This study only provides health checks and advice; it does not test any new drugs or treatments.

Does this replace my usual GP appointments?

No. This check is an extra screening tool. You should continue seeing your GP for your routine health checks and prescriptions.
