Are high levels of CRP dangerous?

High levels of CRP can be considered dangerous depending on your medical history and the underlying cause of the raised levels. HS-CRP can be an indicator of long-term inflammation – which can impact immune system functionality and cause other health issues – and can indicate possible ongoing atherosclerosis (thickening and hardening of the arteries).

What causes inflammation in the body?

Inflammation is normally caused by a cut or injury (acute inflammation), where the body sends out inflammatory cells and cytokines (that stimulate inflammatory cells) to kill off invading microorganisms and heal tissue. Inflammation can also be caused by chronic inflammation where the body does not stop the inflammatory response even though there is no need for your body’s defences to be heightened.

How soon will the test arrive?

If you order your test before midday on a Monday to Friday then your kit will be dispatched the same day. All our kits are sent out via Royal Mail first class post, so it should be with you within 1-2 working days.

How secure is my data?

We have strict processes in place to ensure the protection of your data. Following GDPR the company also operates under tight legal rules about the sharing of data which ensures that data is only shared if it is crucial to the delivery of our service. For example, our doctors see customer results at the time of review, however, after review, access to results is withdrawn.

How do I find out my results are ready?

We keep you updated throughout the process by email and text message. We will let you know when your blood sample has arrived at our lab. Once the blood sample has been analysed one of our doctors will review your results. Once your results are ready, we will email you and send you a text message to let you know your results are ready for you to view in your health dashboard.

How do I take my blood sample

It’s easy to take a finger prick blood sample, but we know for some this can be a bit nerve-wracking, especially if you haven’t done it before. So, we’ve created a how-to video to help you collect a successful sample. But don’t worry if you don’t manage to get it right first time, just contact our customer support team at help@forthsupport.co.uk to request a replacement kit.

Can I have someone take my blood for me?

Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service. A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample. The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

Does a doctor review my results?

We have a team of doctors and nurses who look at all results and will comment on any results that are outside of the normal range for your age.

Can I download the results to share with my GP?

Yes, you can download your results from your health dashboard as a PDF to share with your GP.

What is a hs-CRP blood test?

This high sensitivity CRP test (hs-CRP) is for anyone concerned that their lifestyle might be increasing their risk of inflammation within the body. This could be due to a poor diet, inactive lifestyle, smoking or even intense exercise.

How to test hs-CRP at home

Checking your inflammation levels at home is easy with our hs-CRP finger prick blood test. The kit includes everything you need to collect a small sample of blood at home and post it back to our labs for analysis. You’ll get the results sent back to you via our app within 2 days of our lab receiving your sample, along with comments from our medical team to help you understand them.

What is a normal range of hs-CRP?

We work with NHS labs to measure hs-CRP levels, and the normal range (reference range) for adults is 0-5 mg/L.

High levels of hs-CRP (above 5mg/L) can be caused by illness, infections and autoimmune diseases. Pregnancy and obesity can also cause slightly elevated levels of hs-CRP.

CRP levels above 50mg/L are considered severely elevated^[1] and are often associated with acute bacterial infections.

"C-reactive protein (CRP) is a protein made by the liver, levels increase when there is a inflammation somewhere in the body. The "hs" on the test we offer refers to High Sensitivity which means the test is able to pick up much lower levels of the protein in your blood. Higher levels are linked to increased risk of cardiovascular disease, but can also indicate effects of training impact and spot autoimmune and infective disease."

We’re changing people’s lives

I really like Forth and you probably saved my life because your lab discovered my critically low cortisol which was subsequently diagnosed as adrenal insufficiency by a hospital endocrinologist.

Maria

I find Forth professional and forward-thinking with a bigger range of tests than more traditional healthcare providers in the UK. I think it is closer to what you can get from US providers.

Richard C

I wanted to get more information about my own health instead of using the NHS who just test for a specific reason. I also wanted better historical data to view changes over time as the NHS systems aren’t very good for that.

James W

Finding out what is going on inside your body is key, especially now that the NHS is in crisis. If we can take control of our wellness (and flag up potential problems early) that has got to be a good thing.

Vannesa C

I am very satisfied with your excellent service and I have recommended you to all my friends who are also very interested in your products.
