Private FBC Blood Test

Blood tests play a crucial role in monitoring your health and diagnosing potential medical conditions. One such test that provides valuable insights into your overall well-being is the Full Blood Count (FBC).

We, at City Walk-In Clinic London, provide a full blood count as part of our popular Silver Blood Profile. At just £59, it is great value and provides all relevant information about your full blood count and much more. After all, knowing you have a clean bill of health is priceless.

Full Blood Count Blood Test Overview

A Full Blood Count (FBC) test, also known as a Complete Blood Count (CBC), is a common blood test that assesses the three main types of blood cells: red blood cells (RBCs), white blood cells (WBCs), and platelets.

This test provides valuable information about various health conditions, including anaemia, infections, and certain blood disorders. If your doctor has recommended a full blood count, or if you have questions about your health, please call us today or book online, and let us assist you.

Parameters Measured

Red Blood Cell (RBC) Count: This parameter measures the number of red blood cells in a given volume of blood. It helps determine if there is a deficiency or excess of RBCs, which may indicate conditions such as anaemia or polycythaemia.

Haemoglobin (Hb) Levels: Haemoglobin is the protein in RBCs responsible for transporting oxygen throughout the body. Haemoglobin levels help evaluate oxygen-carrying capacity and can indicate aneamia or other blood disorders.

Haematocrit (Hct) Levels: Haematocrit measures the percentage of the blood volume occupied by red blood cells. Abnormal levels may indicate dehydration, anaemia, or other underlying conditions.

White Blood Cell (WBC) Count: WBCs are crucial for our immune system and help fight off infections. A WBC count determines the number of white blood cells in a given volume of blood, aiding in the diagnosis of infections, autoimmune disorders, or leukaemia.

Platelet Count: Platelets are responsible for blood clotting, preventing excessive bleeding. Platelet counts help assess the risk of bleeding or clotting disorders.

Typical Full Blood Count Results

Understanding full blood count test results requires the expertise of a healthcare professional. They will consider various factors such as your age, gender, medical history, and symptoms. Here are a few general full blood count blood result interpretations:

Normal Range: Values within the reference range indicate that blood cell counts are within the expected healthy range.
Low Counts: Lower than normal counts may suggest conditions like anaemia (low RBCs or haemoglobin), infections (low WBCs), or thrombocytopenia (low platelets).
High Counts: Elevated counts could indicate conditions like polycythaemia (high RBCs), infection or inflammation (high WBCs), or thrombocytosis (high platelets).

Possible Test Outcomes Explained

Always consult with a healthcare professional for proper diagnosis and treatment recommendations based on your specific test results.

Red Blood Cells:

A low red blood cell count may indicate anaemia or bleeding.
A high red blood cell could suggest dehydration or certain lung diseases.

Platelets:

A low platelet count may indicate bleeding disorders or conditions affecting platelet production.
A high platelet count could suggest inflammation or a response to injury.

White Blood Cells:

High levels of white blood cells may indicate infection, inflammation, or stress.
Low levels of white blood cells could indicate certain viral infections or bone marrow issues.
High or low levels of specific white blood cell types can indicate different infections, immune disorders, or leukemia.

I had a fantastic experience at the Harley Street clinic. Staff were very welcoming and professional and booked my second blood test here also.

Truman Packard

The service was efficient, personable and very complete. The doctor who saw me was very good, patient and sensitive. I’ll be going back.

Sue Heald

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.

Mary Anne

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.

Can anything affect the accuracy of the Full Blood Count test?

Dehydration can concentrate your blood and falsely raise cell counts. Recent infections, medications (such as chemotherapy or steroids), or chronic diseases can also alter blood counts. And physical activity before the test or even stress may impact some components. That is why it is vital to inform your healthcare provider about any medications, illnesses, or unusual activity or symptoms before testing.

Can a Full Blood Count (FBC) blood test diagnose specific medical conditions?

While a Full Blood Count (FBC) blood test can provide valuable information about your overall health, it is not typically used to diagnose specific medical conditions on its own. However, abnormal results from an FBC test may prompt further testing or investigation to determine the underlying cause of any abnormalities.

Is a Full Blood Count (FBC) blood test covered by insurance?

Whether a Full Blood Count (FBC) blood test is covered by insurance depends on your specific insurance plan and the reason for the test. Some insurance plans may cover the cost of an FBC test as part of routine preventive care or to evaluate specific symptoms or medical conditions. It’s important to check with your insurance provider to understand your coverage and any potential out-of-pocket costs.

Can a Full Blood Count detect cancer?

While an FBC test cannot definitively diagnose cancer, it can provide important clues. For example, abnormal white blood cell counts or the presence of immature blood cells can suggest blood cancers like leukemia or lymphoma. If the FBC results are suspicious, your doctor may recommend more specific tests to confirm a diagnosis.
