Key Diagnostic For Organ Health

A Comprehensive Metabolic Panel (CMP) is an important diagnostic test that helps identify several different conditions, monitors chronic diseases, and ensures organs are functioning correctly.

Our test, conducted at our clinics in London, consists of a group of blood tests that help outline the body’s overall chemical balance and metabolism to assess the functioning of the liver and kidneys.

Doctor considering blood test options

What Does A CMP Blood Test Measure?

A CMP typically screens about 14 different elements within the blood, all performed using a single sample. It tests for:

  • Sodium
  • Glucose
  • Calcium
  • Bilirubin
  • Albumin
  • Potassium
  • Creatinine
  • Total Protein
  • Blood Urea Nitrogen (BUN)
  • Alkaline Phosphatase (ALP)
  • Alanine Aminotransferase (ALT)
  • Aspartate Aminotransferase (AST)

Here Is Why This Test Is Essential

A CMP plays an important role in the diagnosis and follow-up of patients with many disease states. It provides information on the following:

  • One may have impaired kidney function if one’s creatinine or BUN levels are very high.
  • Increased ALT, AST, bilirubin, or ALP may denote liver disease or damage.
  • Monitoring and managing diabetes-glucose is an important test in the diagnosis and assessment of diabetes.
  • Dehydration, heart conditions, or kidney problems can be indicated by an imbalance of electrolytes, including sodium, potassium, and chloride.

Is It Time For A CMP?

If you are experiencing unexplained symptoms like fatigue, nausea, or swelling or a condition like diabetes or high blood pressure that requires ongoing monitoring, your doctor may recommend a CMP blood test.

Comprehensive Metabolic Panels are also useful before surgeries or as part of routine health check-ups. Remember, approximately 14 million adults in the UK have high blood pressure (hypertension), with about 5 million of these individuals remaining undiagnosed, as the condition often presents no symptoms. Similarly, as of early 2025, around 4.6 million people in the UK have been diagnosed with diabetes, marking an all-time high. Plus, an estimated 1.3 million individuals are living with undiagnosed type 2 diabetes, and about 6.3 million have prediabetes.

Benefits Of Getting A CMP Blood Test

A Comprehensive Metabolic Panel can help:

  • Assess Overall Health
  • Detect Liver Problems
  • Monitor Kidney Function
  • Track Blood Sugar Levels
  • Assess Electrolyte Balance
  • Evaluate Nutritional Status
  • Detect Early Signs Of Disease
  • Aid In Diagnosing Hormonal Imbalances
  • Help Diagnose Metabolic DisordersMonitors Medication Effects

preparing for appointment

Preparing for test

You may be asked to not eat or drink (except water) anything for 8 to 12 hours before the test. Check with your doctor about specific instructions on fasting. Be prepared to give your medical history, including what health problems you have now or have had, what medicines you use, and if you have had a recent illness or surgery.

during the appointment

During the test

To perform the test, blood is drawn most frequently from a vein in your arm. The skin is first cleaned with an antiseptic. Then, a small needle is inserted into the vein, which allows the blood to flow into one or more vials. The entire process typically takes only a few minutes.

post appointment

Test results are usually available in a few days. The provider will discuss the test results with you and tell you what they mean for your health. If an abnormality is seen, you might need additional testing or treatment.

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.

What do abnormal CMP results mean?
Abnormal test results can mean there is a problem with your health. For example, high blood sugar might mean you have diabetes or are at risk of getting it. If your liver enzymes are high, it could be a sign of liver damage or inflammation, etc. Therefore, your doctor will look at your test results along with your symptoms and medical history to decide what to do next.
Can a CMP be used to monitor on-going health conditions?
Yes, through a Comprehensive Metabolic Panel, a number of chronic health conditions, including diabetes and kidney disease, may be monitored. Since the CMP gives a snapshot of metabolic function and organs, healthcare providers may use it to assess how well a patient’s condition is being managed and whether treatments are effective. It can also help in early detection of any complication or alteration in the health status through periodic CMP testing, thus helping in reassessing and readjustments of treatment plans accordingly.
What should I discuss with my healthcare provider about CMP results?
As you go through the CMP results with your health professional, point out any of your concerns based on the values reported. Discuss possible follow-up tests you might need for further evaluation or clarification of abnormal findings. Also, you might want to know about the available treatments based on your results, or if there are any life changes you would want to make, such as dietary or exercise-wise, that would be beneficial to help you with bettering your overall health and well-being. This discussion will, in turn, provide you with the chances of being in a position to play an active role in your health management.
Can I take a CMP test if I’m feeling well, or is it only for people with symptoms?
Yes, a CMP is commonly used as part of routine health screenings, even if you feel perfectly fine. Remember, many early signs of chronic conditions like kidney disease, liver issues, or diabetes do not cause noticeable symptoms until the condition has progressed. That is why this test is invaluable, as a CMP can catch imbalances early, allowing for timely treatment or lifestyle changes that prevent further complications.
