Understanding Diagnostic Blood Tests: Insights from a London Medical Practitioner

As experienced medical practitioners operating a clinic in the heart of London, we encounter numerous patients who are curious or even apprehensive about diagnostic blood tests. It’s completely natural to have questions or concerns about these tests, which play a crucial role in modern wellbeing.

In this blog, we aim to demystify the process and importance of blood tests, covering various types, from hormone and vitamin levels to early detection of health issues.

The Importance of Diagnostic Blood Tests

Blood tests are an integral part of modern care, offering invaluable insights into the state of your body’s health. As a seasoned practitioner in London, I’ve seen firsthand the critical role these tests play in diagnosing and managing various health conditions.

Firstly, these tests provide a window into your body’s complex systems. They can reveal how well your organs, such as the liver and kidneys, function, which is essential for detecting diseases early. For example, a liver function test can detect liver damage before symptoms appear, allowing for timely intervention.

Moreover, blood tests are crucial in identifying infections, inflammations, and autoimmune disorders. By measuring markers like white blood cell count and C-reactive protein, we can detect infections and inflammations even before they manifest significant symptoms. This early detection is key to starting treatments that can prevent complications.

In managing chronic diseases like diabetes and high cholesterol, regular blood tests are indispensable. They help monitor the effectiveness of treatments and make necessary adjustments. For diabetic patients, regular blood glucose testing is vital to keep their condition under control and to prevent serious complications. Blood tests are also pivotal in assessing heart health. By measuring cholesterol and triglyceride levels, we can gauge your risk of heart disease and stroke, enabling us to advise on lifestyle changes to lower that risk.

In the realm of preventive care, blood tests offer a proactive approach to managing your health. By identifying risk factors and early signs of disease, these tests enable individuals to make informed lifestyle changes or seek early treatment, potentially averting serious health issues down the line.

Types of Available Blood Tests

Vitamin Levels

Altered vitamin levels can lead to fatigue/weakness/skin problems/reduced energy levels etc. We can check the levels of specific vitamins in your blood and replace them if necessary. One of the most common deficiencies is Vitamin B12, which we regularly replace with injections.

Hormone Levels & Imbalances

As we age, our hormone levels can change, causing many unexpected symptoms. We work closely with a hormone specialist and can refer you as appropriate. These tests are essential for women who are potentially peri/menopausal and can be crucial for men, to measure testosterone and prostate levels.

Early Detection of Health Issues

We offer specific blood tests to determine the risks of patients developing several cancers and possibly even disorders of the brain, such as dementia. Early detection is often crucial in managing and mitigating the impact of various diseases.

Preventative Health Measures

These tests provide a proactive approach to healthcare, enabling individuals to identify and address potential risk factors before they manifest into severe conditions.

Monitor Chronic Health Conditions

For individuals with chronic conditions, regular blood tests are crucial for monitoring disease progression, adjusting treatment plans, and maintaining overall health and quality of life.

Assess Organ Functions

Blood tests provide insights into the functioning of vital organs such as the liver, kidneys, and thyroid. This information is essential for understanding the overall health of these organs and identifying any potential issues.

Nutritional Insights

One of the most common blood tests performed for people is to assess nutrient levels in the body. This can help individuals and healthcare professionals understand any deficiencies or excesses. This information is valuable for crafting nutrition plans that support overall well-being.

Objective Health Tracking

Regular blood tests provide quantifiable data for tracking health changes over time. This objective information facilitates a more accurate evaluation of the effectiveness of lifestyle modifications, medications, or other interventions.

Metabolic Age

By doing a very advanced/new blood test, we can accurately work out a person’s metabolic age. Metabolic age is considered our true age at a cellular level. We can then review the results and implement necessary changes in lifestyle/diet/exercise, etc, to improve this. You can then re-test the metabolic age to ascertain the improvement.

Dermal Filler Allergy Testing (Exclusive to Dr Parikh)

Our exclusive test includes a genetic test using a mouth swab to check for any possible allergic reactions to dermal fillers. It can also ascertain if patients who have autoimmune diseases, such as Rheumatoid Arthritis, could have these injections safely.

Preparing for a Blood Test and what to expect

Blood tests are a very simple, easy and comfortable procedure, however for those who have not had them before there can be some uncertainty about what to expect.

Preparation can vary depending on the type of test. Some require fasting, while others do not. Your practitioner will provide specific instructions prior to your testing to ensure accurate results.

At our London clinic, we ensure that blood tests are as comfortable and stress-free as possible. The process typically involves drawing a small amount of blood from a vein, usually in your arm, and it only takes around 5 minutes in total. Blood tests can easily be factored into a busy lifestyle, and can be performed on a lunchtime or whenever you have a spare 10 minutes, without impacting your day. 

Interpreting your Results

Interpreting the results of blood tests is a critical and nuanced aspect of wellbeing, one that requires expertise and a comprehensive understanding of your health history. In our London clinic, we prioritise not just conducting these tests, but also ensuring that you fully understand what the results mean for your health.

When you receive your blood test results, they will typically come in the form of numbers, often compared against a ‘normal’ range. These ranges are established based on average values obtained from the general population. However, it’s crucial to understand that ‘normal’ can vary significantly between individuals. Factors such as age, gender, ethnicity, and overall health can influence these ranges.

For instance, if a blood test shows a high level of a certain enzyme, it might suggest liver inflammation. However, without considering the context – such as recent medication, alcohol consumption, or even a strenuous workout prior to the test – the result might be misleading. That’s where the role of a professional becomes essential. We interpret these results in the context of your entire health profile.

Results at our clinic in London are typically returned within 48 hours.
