Preventive examinations – which ones should be done regularly?

Introduction
Alongside a balanced diet, regular exercise and appropriate supplementation, preventive screening is a core pillar of health. Carrying out routine checks helps identify changes before they become bigger problems.

Leading medical societies recommend a set of periodic tests which, used strategically, can save lives.

  1. Full blood count with differential – first-line screening
    A basic, low-cost test that provides essential information about overall status, including anaemia, infections, allergic reactions and immune function. Experts highlight the value of assessing neutrophils, eosinophils and lymphocytes.

  2. Ferritin – iron stores and gut health
    Ferritin is a key marker of iron reserves. Low values (<50 ng/mL) may indicate weakness, hormonal imbalance or chronic fatigue, as well as digestive issues such as leaky gut, intolerances or infections.

  3. CRP – a detector of chronic inflammation
    Raised C-reactive protein (CRP) without obvious symptoms can point to hidden inflammation. Experts recommend including it in comprehensive reviews, since conditions like dental disease can significantly impact overall health.

  4. Insulin, glucose and HOMA – for everyone
    Insulin resistance can develop silently. The HOMA index should be below 1.5; higher values increase the risk of type 2 diabetes, obesity and hormonal disorders. Physical activity, diet, sleep and stress management are essential to keep it in check.

  5. Lipid profile – not just LDL
    Specialists note that high triglycerides (>150 mg/dL) and the triglyceride/HDL ratio are more informative than LDL in isolation. Cutting sugar and trans fats is key to improving these markers.

  6. Liver tests – ALT and AST
    Values that are “within range” but elevated can still mask problems. Readings above 25 U/L may indicate fatty liver, often linked to poor dietary habits and chronic stress.

  7. Thyroid – more than TSH
    A complete assessment should include fT3, fT4, anti-TPO and anti-TG antibodies, plus a thyroid ultrasound. This integrated approach helps prevent hormonal imbalances that affect weight, energy, mood and immunity.

  8. Vitamin D3 – the “hormone of life”
    Vitamin D3 is crucial for bone, immune and hormonal health. Experts suggest optimal levels above 50 ng/mL, with testing of 25(OH)D3 to tailor supplementation.

  9. Homocysteine, B12 and iron – heart protection
    Elevated homocysteine (>10 µmol/L) is a cardiovascular risk factor. Measuring it alongside B12 and ferritin provides a fuller picture of cardiac and metabolic health.

  10. Ultrasound and imaging studies
    Imaging complements blood tests. Abdominal, thyroid, breast or prostate ultrasounds can detect early changes, even before symptoms. Many experts recommend performing them every two years.

Summary
Prevention through regular medical screening is an investment in health. Acting before symptoms appear allows for simpler, more effective treatment. Building these tests into a comprehensive health plan supports early detection and a better quality of life.
