Tiredness Screening Blood Test
Check key blood biomarkers to determine the cause of fatigue and tiredness.
What is this test?
Persistent fatigue can have many causes - lifestyle, medical, emotional, or psychological. Though tiredness may signal an underlying health issue, symptoms alone cannot diagnose. A tiredness screening blood test checks key blood biomarkers to help determine the cause of chronic fatigue or tiredness.
- Lack of energy and constant fatigue not relieved by rest
- Mental exhaustion, difficulty concentrating and remembering
- Physical weakness, heavy limbs, reduced activity tolerance
- Sleep disturbances and non-refreshing sleep
- Decreased motivation and interest in activities
- Slowed reflexes and reaction time
- Muscle aches, joint pain and body discomfort
- Mood changes like irritability, anxiety and depression
- Increased sensitivity to stress and feeling easily overwhelmed
- Frequent illnesses and infections due to weakened immunity
How long does it take?
The test turnaround is 48 hours.

What is included in this test
Full blood count (FBC)
Measures the number and type of cells in your blood, such as red blood cells, white blood cells, and platelets and it provides important insights into overall health by evaluating blood components essential for oxygen transport, immunity, and clotting. It can help to detect anaemia, infections, bleeding disorders, and other abnormalities.
Anaemia Markers represent essential indicators to diagnose and monitor anaemia. These markers can provide insights into iron storage and utilisation within the body, helping to determine potential deficiencies or imbalances.
Erythrocyte Sedimentation Rate (ESR) provides insights into ongoing inflammatory processes.
Free Thyroxine (FT4) and Thyroid Stimulating Hormone (TSH) are important health markers for evaluating thyroid function. Their measurements offer insights into the thyroid gland's function and help diagnose conditions like hyperthyroidism or hypothyroidism.
Vitamin B12, folate, and vitamin D are essential vitamins that play important roles in many bodily functions. Low levels of these vitamins can lead to a variety of symptoms, including fatigue, weakness, pale skin, tingling or numbness in the hands and feet, and shortness of breath.

Rule out underlying medical conditions
Fatigue can be a symptom of various underlying medical conditions, such as anaemia, thyroid disorders, diabetes, chronic infections, autoimmune diseases, or hormonal imbalances. A blood test can help identify or rule out these conditions by evaluating specific markers related to tiredness.
Fatigue can be associated with deficiencies in vital nutrients, such as iron, vitamin D, vitamin B12, or folate. Blood tests can assess the levels of these nutrients and determine if supplementation or dietary changes are necessary.
Hormonal imbalances, such as thyroid hormones can contribute to persistent fatigue and tiredness. Blood tests can help assess hormone levels and guide appropriate treatment or management strategies.
Chronic inflammation in the body can cause fatigue. Blood tests that measure markers of inflammation, such as erythrocyte sedimentation rate (ESR), can help identify the presence of underlying inflammatory conditions that may contribute to your tiredness.
