What’s included in this test

White blood cells 6 markers
White Blood Cells (WBC)
WBC count indicates immune system activity. Elevated levels can suggest infection or inflammation, while low levels may reflect bone marrow suppression or immune deficiency.
Red blood cells 7 markers
Red Blood Cells (RBC)
RBC count measures the number of red blood cells in your blood. It's key to assessing oxygen-carrying capacity and diagnosing anaemia or bone marrow issues.
Haemoglobin (Hb)
Haemoglobin carries oxygen from your lungs to the rest of your body. Low levels may indicate anaemia, while high levels could signal dehydration or other blood disorders.
Haematocrit (HCT)
HCT shows the percentage of blood made up of red blood cells. It helps assess anaemia, dehydration, and overall blood volume status.
Mean Corpuscular Volume (MCV)
MCV reflects the average size of your red blood cells. It helps classify types of anaemia — whether cells are too large, too small, or just right in size.
Mean Corpuscular Haemoglobin (MCH)
MCH indicates the average amount of haemoglobin in each red blood cell. Abnormal levels help identify different forms of anaemia.
Mean Corpuscular Haemoglobin Concentration (MCHC)
MCHC shows the concentration of haemoglobin in your red blood cells. It's useful in evaluating anaemia types and red cell colour (hypochromia).
Red Cell Distribution Width (RDW)
RDW measures the variation in size of your red blood cells. It helps identify types of anaemia and can indicate nutrient deficiencies such as iron, B12, or folate.
Clotting status 2 markers
Platelets (PLT)
Platelets are responsible for blood clotting. Low levels may lead to bleeding, while high levels can increase the risk of thrombosis.
Mean Platelet Volume (MPV)
MPV reflects the average size of your platelets. It provides insight into platelet production and activity, and can help assess risk of clotting or bleeding disorders.
White blood cells 6 markers
Lymphocytes (Ly)
Lymphocytes help fight viral infections and are vital to your immune memory. Abnormal levels can be seen in viral illnesses or immune disorders.
Monocytes (Mo)
Monocytes assist in clearing infections and dead cells. Elevated levels may indicate chronic inflammation or certain infections.
Neutrophils (Ne)
Neutrophils are your body’s first line of defense against infection. High levels usually indicate bacterial infections or inflammation.
Eosinophils (Eo)
Eosinophils are a type of white blood cell involved in allergic reactions and fighting parasites. Elevated levels may suggest allergy, asthma, or parasitic infection.
Basophils (Ba)
Basophils are white blood cells that release histamine during allergic responses. They are rarely elevated but may increase in certain chronic inflammatory conditions.
Electrolytes 3 markers
Sodium
Sodium is critical for fluid balance, nerve function, and blood pressure regulation. Abnormal levels can point to kidney, adrenal, or hydration issues.
Liver health 8 markers
Total protein
Total protein includes albumin and globulin. It's used to assess liver function, kidney health, and nutritional status.
Kidney health 3 markers
Creatinine
Creatinine is a waste product filtered by your kidneys. Measuring creatinine helps assess kidney function and detect early signs of kidney disease.
eGFR (estimated Glomerular Filtration Rate)
eGFR estimates how well your kidneys are filtering waste from your blood. It's a key indicator of kidney function and is especially useful for early detection of chronic kidney disease (CKD).
Urea
Urea is a byproduct of protein metabolism, filtered by the kidneys. High levels may indicate impaired kidney function or dehydration.
Liver health 8 markers
Globulin
Globulin is a group of proteins involved in liver function, immune response, and blood clotting. Abnormal levels can point to infections, liver disease, or immune system disorders.
Albumin
Albumin is a major protein in the blood, essential for maintaining fluid balance and transporting nutrients. Low levels can signal liver or kidney disease.
Bilirubin (Total)
Total bilirubin helps assess liver function and red blood cell breakdown. High levels can cause jaundice and indicate liver or gallbladder issues.
Alanine Aminotransferase (ALT)
Alanine Aminotransferase (ALT) is an enzyme mainly found in the liver. Elevated levels can indicate liver damage from conditions like hepatitis or fatty liver disease.
Gamma-Glutamyl transpeptidase (GGT)
GGT is an enzyme found in the liver and bile ducts. It's commonly tested to evaluate liver function and detect bile duct obstructions or alcohol-related liver damage.
Alkaline phosphatase (ALP)
ALP is an enzyme related to the liver, bones, and bile ducts. It's often tested to investigate liver function or bone disorders.
Aspartate Aminotransferase (AST) (SGOT)
AST is an enzyme found in the liver and muscles. Elevated levels can indicate liver damage, muscle injury, or other underlying conditions.
Minerals 2 markers
Calcium
Calcium is crucial for bones, muscle contraction, and nerve transmission. This test helps diagnose parathyroid issues or monitor supplementation and diet.
Corrected Calcium
Corrected calcium accounts for albumin levels in your blood to give a more accurate reading of biologically active calcium. It’s essential for evaluating bone health, muscle function, and parathyroid activity, especially in individuals with abnormal protein levels or chronic illness.
Electrolytes 3 markers
Potassium
Potassium is an essential electrolyte for heart rhythm, muscle contractions, and nerve signals. Imbalances can lead to serious health issues.
Chloride
Chloride helps regulate fluid balance, blood pressure, and pH levels. It's usually measured with other electrolytes to assess hydration and kidney function.
Inflammation 1 marker
C Reactive Protein (CRP)
CRP is a marker of inflammation in the body. Elevated CRP may indicate infection, autoimmune disorders, or increased cardiovascular risk.
Immunoglobulins 3 markers
Immunoglobulin G (IgG)
IgG is the most abundant antibody class and reflects long-term immune responses.
Immunoglobulin M (IgM)
IgM is the first antibody produced in response to a new infection.
Immunoglobulin A (IgA)
IgA is the antibody found in mucosal surfaces and blood; it is measured alongside coeliac and immune screens.

Common questions 16 questions
Where are you located?
Our flagship clinic and laboratory are at 41–42 Foley Street, Fitzrovia, London W1W 7TS, a few minutes' walk from Oxford Circus (Central, Victoria and Bakerloo lines), Warren Street (Victoria and Northern), Goodge Street (Northern), Tottenham Court Road (Central and Elizabeth) and Great Portland Street (Circle, Metropolitan and Hammersmith & City).
How will I receive my results?
All results will be sent out by email. Please ensure you have provided us with the best email to reach you on.
How do I prepare for my test?
In most cases, there is no preparation needed. With particular tests, we recommend fasting for 8-10 hours ahead. These tests include glucose, cholesterol/lipid profile and homocysteine. In the event that it is difficult for you to fast, this will be noted by the phlebotomist, and where applicable adjusted reference ranges applied. If you are unsure whether you need to fast, please confirm.
How can I contact Clinilabs?
For all patient enquiries you can contact the reception by phone/whatsapp on 020 4525 8805 or via email: info@clinilabs.co.uk. For careers at Clinilabs please email careers@clinilabs.co.uk
Do you work with the NHS?
We are a private laboratory, and do not currently offer NHS services.
Can I speak with a doctor about my results?
We can provide written clinical interpretations and/or virtual/in person consultations for your results. These are additional services and are not included in the price of your tests. Please enquire if you are interested in these services. The price of the tests includes a report that you will receive by email which includes your results as well as (where applicable) reference ranges and indications whether you fall outside of these.
How long will my results take?
At Clinilabs we do our best to give your results to you as soon as possible. Each test has an estimated turnaround time which can be found on each test’s page on our website. Please note that these are estimates and whilst we typically provide results sooner than advertised, we may in some cases require more time. If you are unsure about the turnaround time of your specific test and or require tests urgently, please confirm ahead of your visit.
Do you accept insurance?
We do partner with medical insurance providers such as Bupa UK, Bupa Global, Allianz, Cigna, WPA, Vitality. Please note that pre-authorisation is required for payment by insurance. We will also require payment card details to be kept on file; which will only be used in the event your insurance company does not cover your treatment. Please note that prices can vary greatly between insurance companies, and promotional online-only prices may not reflect prices charged if direct billing is being undertaken.
What is a panel/profile?
A panel (or profile) is a group of single tests chosen together to answer one question, such as iron status, thyroid function or a general health check. Booking the panel is cheaper than booking each marker separately, and the markers are reported together so they can be read in context. Each panel's page lists exactly what it includes.
I'm not sure which test I need?
If you are unsure which test you need, we recommend taking a look at some of our packages. Our website is divided by section and our clinical team have designed a number of panels to suit the most common requests. If still unsure, pleas feel free to contact us by whatsapp/phone/email for guidance. Ultimately, while our team may advise on our offerings, we recommend checking with your doctor as the ultimate responsibility is on the customer to select their tests.
Do I need to fast before my test?
Some blood tests require fasting, but many do not. For example, glucose, cholesterol/lipid profile and homocysteine are among some of the tests needed to fast between 8 - 12 hours. If fasting is required, we recommend doing so overnight and scheduling your appointment for the morning. This helps minimise discomfort from going without food. During the fasting period, you should stay well-hydrated, water is ideal, and you may also have clear, calorie-free fluids such as black tea or black coffee (without milk or sugar). If you are on medication, please check with your referring doctor if you need to fast. If you are self-referring, then you can call us to find out our recommendation. Please note: If you are unable to fast, this will be noted and adjusted reference ranges applied.
Why are my Clinilabs blood test results different from my other blood test results?
It’s completely normal to see slight differences in blood test results between different laboratories. These variations can occur for several reasons: Analytical variation: Even when the same sample is tested multiple times on the same machine, small differences can occur. This is called analytical variation and is measured using the coefficient of variation (CV). For example, total cholesterol has a typical CV of around 3% at a level of 5.0 mmol/L, meaning results between 4.85 and 5.15 mmol/L are entirely expected and not clinically significant. Test-specific variability: Some tests, especially hormone tests, naturally show more variation. These tests can have CVs ranging from 3% to 10%, so minor result changes are common and generally not a cause for concern. Laboratory differences: Each lab may use different analysers, reference ranges, or testing methods. Even factors like sample type, collection time, and processing date can lead to slight result differences. Biological variation: Your body’s own levels can fluctuate throughout the day due to stress, sleep, meals, or hormonal cycles. These natural changes can influence your test results as well.
Can I collect my blood sample at home?

A home finger-prick kit may be self-collected where the selected blood test is suitable for capillary sampling. Follow the kit instructions carefully, because not every test can use a finger-prick sample.

A venous blood draw must not be self-collected: it must be performed by a qualified healthcare professional who is trained and competent in phlebotomy. You can arrange this at a Clinilabs partner clinic or, where offered, as a home visit.

Can my child come to Clinilabs?
At this point in time you must be over 16 to attend Clinilabs. We may however be able to arrange pediatric home visits for children. This is subject to availability. Please enquire with reception if you are interested in this.
Do I need a doctor's referral?
For the majority of tests you do not need to have a referral, but you do need to know which test or set of tests you will need to have. Whilst we can (when possible) help to explain tests available, it is the patient’s responsibility to select the correct test/s, if requested by their doctor. For some specialist tests, you may require a doctors referral. This will be communicated to you upon enquiry.
How do I book an appointment at a partner clinic?
Order your test online and choose the partner clinic option at checkout. We then post you a collection kit, and inside it is a unique booking code. Once the kit has arrived, go to clinics.clinilabs.co.uk, enter the code and choose a clinic and time that suit you. You cannot book before the kit arrives, because the code is needed to make the booking. Take the kit with you to the appointment. After your sample is taken, you post it back to our laboratory yourself using the pre-paid label in the kit.

Most private blood test providers in London send your blood elsewhere. We are the laboratory.
