Levitas Diagnostics | London (Mayfair, Knightsbridge, Kensington) & Surrey (Guildford, Esher)
Feeling constantly tired is one of the most common yet most misunderstood symptoms in modern healthcare.
At Levitas Diagnostics, we see patients daily who have been told:
“Your blood tests are normal.”
- PPersistent fatigue
- PBrain fog
- PLow motivation
- PPoor recovery
The reality is simple:
Standard testing often misses the root cause.
If you’re searching for answers through blood tests for fatigue, this guide will show you how advanced fatigue testing in the UK can uncover what conventional medicine overlooks.
Why Am I Always Tired? The Real Causes
Fatigue is rarely caused by one issue alone. It is usually a combination of:
Mitochondrial dysfunction
Nutrient deficiencies
Hormonal imbalance
Chronic inflammation
Neurotransmitter disruption
At Levitas, we approach fatigue as a multi-system imbalance, not just a symptom.
The Problem with Standard Testing
Basic NHS or routine panels often include:
- Full blood count
- Thyroid (limited markers)
- Basic iron levels
While useful, they do not assess:
- Cellular energy production
- Micronutrient status
- Neurotransmitter balance
- Functional deficiencies
This is why many patients with chronic fatigue are left without answers.
Key Blood Tests for Fatigue (Advanced Approach)
Micronutrient Test for Low Energy
Your body depends on vitamins and minerals to produce energy.
Key Nutrients Assessed
- B vitamins (especially B12, B6, folate)
- Magnesium
- Zinc
- Vitamin D
Why It Matters
Even mild deficiencies can lead to:
- Fatigue
- Brain fog
- Poor recovery
At Levitas, we use advanced micronutrient testing to assess intracellular levels—not just serum values.
Essential Minerals Blood Test
Minerals are the electrical conductors of the body.
Low levels can disrupt
- Muscle function
- Nerve signalling
- Energy production
Common Symptoms
- Fatigue
- Weakness
- Poor sleep
- Muscle tension
Iron Support Test for Tiredness
Iron is critical for oxygen transport.
Beyond Basic Iron
We assess
- Ferritin (storage iron)
- Transferrin saturation
- Total iron-binding capacity
Why It Matters
Low iron—even within “normal” ranges—can cause:
- Chronic tiredness
- Breathlessness
- Reduced stamina
CoQ10 Test for Fatigue
CoQ10 is essential for mitochondrial energy production.
Think of CoQ10 as
The spark plug of your cellular engine
Low levels can result in
- Severe fatigue
- Muscle weakness
- Poor endurance
This is particularly relevant for
- Patients on statins
- Individuals with chronic fatigue syndromes
Neurotransmitter Test for Fatigue
Energy is not just physical—it is neurological.
Key Neurotransmitters
- Dopamine (motivation)
- Serotonin (mood)
- GABA (calmness)
Symptoms of Imbalance
- Low motivation
- Mental fatigue
- Poor focus
At Levitas Diagnostics, we explore brain chemistry as part of fatigue assessment.
Hormonal and Metabolic Testing
Fatigue is often linked to hormonal imbalance.
Key Areas
- Thyroid (full panel, not just TSH)
- Cortisol (stress hormone)
- Testosterone / DHEA
Why It Matters
Hormonal dysregulation can:
- Drain energy
- Disrupt sleep
- Affect mood and drive
Chronic Fatigue Diagnosis: A New Perspective
Chronic fatigue is not a single disease—it is a signal.
At Levitas, we redefine chronic fatigue diagnosis as:
“Understanding where the system has lost efficiency.”
This includes:
- Energy production
- Nutrient availability
- Hormonal balance
- Detox pathways

FAQs: Blood Tests for Fatigue
1. What are the best blood tests for fatigue?
A combination of micronutrient, iron, hormonal, and mitochondrial markers provides the most insight.
2. Why do I feel tired even if my blood tests are normal?
Standard tests often miss functional deficiencies and cellular imbalances.
3. What is advanced fatigue testing in the UK?
It includes deeper analysis of nutrients, hormones, and cellular energy markers.
4. Can a micronutrient test help low energy?
Yes, deficiencies in vitamins and minerals are a common cause of fatigue.
5. What is a CoQ10 test for fatigue?
It measures levels of a key molecule involved in energy production within cells.
6. How does iron affect tiredness?
Low iron reduces oxygen delivery, leading to fatigue and low stamina.
7. What is included in an essential minerals blood test?
Magnesium, zinc, and other key minerals that support energy and nerve function.
8. Can neurotransmitter testing explain fatigue?
Yes, imbalances can affect motivation, focus, and mental energy.
9. Is fatigue linked to hormones?
Absolutely—thyroid, cortisol, and testosterone all play key roles.
10. How accurate are fatigue blood tests?
Advanced testing provides a much clearer picture than standard panels.
