Routine blood tests are one of the simplest ways to gain insight into your health.
Many conditions develop gradually and may not cause noticeable symptoms in the early stages. Regular blood tests can help identify changes before they become more serious, allowing early treatment or lifestyle adjustments.
At Fleet Street Clinic, we often recommend a core group of blood tests that provide a useful overview of your metabolic health, organ function and long-term risk factors.
These tests aren’t about looking for problems unnecessarily. They’re about understanding how your body is functioning and identifying anything that may benefit from attention.
Here are six blood tests that are commonly included in an annual health review:
1. Full Blood Count (FBC)
A full blood count provides a broad overview of your general health.
It measures the levels of red blood cells, white blood cells and platelets in your blood. Changes in these levels can sometimes indicate conditions such as anaemia, infection, inflammation or problems affecting the immune system.
Many people discover issues such as iron deficiency through routine blood testing, often before symptoms become significant.
2. Lipid Profile (Cholesterol Test)
A lipid profile measures different types of cholesterol in the blood, including LDL (“bad” cholesterol), HDL (“good” cholesterol) and triglycerides.
These levels are important indicators of cardiovascular risk. Elevated cholesterol often develops silently and may not cause symptoms until significant disease has developed.
Monitoring cholesterol levels allows early lifestyle changes or treatment to reduce the risk of heart disease and stroke.
3. HbA1c (Blood Sugar Control)
HbA1c measures average blood glucose levels over the previous two to three months.
It is widely used to diagnose and monitor diabetes and pre-diabetes. Many people are unaware that their blood sugar levels are rising until it is identified during routine screening.
Detecting early changes allows patients to address diet, weight, exercise and metabolic health before diabetes develops.
4. Liver Function Tests (LFTs)
Liver function tests assess enzymes and proteins that reflect how well the liver is working. The liver plays a vital role in metabolism, detoxification and digestion. Abnormal liver tests may be linked to alcohol intake, medications, fatty liver disease or viral infections. Early detection allows doctors to investigate further and prevent progression.
5. Thyroid Function Tests
The thyroid gland regulates metabolism, energy levels and hormone balance.
An underactive thyroid (hypothyroidism) can cause fatigue, weight gain, dry skin and low mood, while an overactive thyroid (hyperthyroidism) may cause anxiety, palpitations and weight loss.
Thyroid disorders are relatively common and can often be detected easily through blood tests.
6. Vitamin D Levels
Vitamin D plays an important role in bone health, immune function and muscle strength.
Low levels are very common in the UK, particularly during the winter months when sunlight exposure is limited. Symptoms of deficiency can include fatigue, muscle aches and low mood.
Identifying deficiency allows appropriate supplementation and monitoring.
Blood tests provide a valuable snapshot of your health. They can help identify early warning signs of conditions such as diabetes, cardiovascular disease, anaemia or thyroid disorders often before symptoms become noticeable.
Regular monitoring also allows changes to be tracked over time, which can be particularly helpful in understanding long-term health trends.
Whilst these 6 tests provide a useful starting point, the most appropriate screening tests will depend on your age, medical history and individual risk factors.
At Fleet Street Clinic, our doctors take a personalised approach to preventive health. Blood tests are reviewed alongside lifestyle, symptoms and medical history to ensure results are interpreted in the right context.
