This advanced Energy Test investigates the most common nutritional, hormonal, and metabolic imbalances that cause fatigue, low motivation, brain fog, and poor physical performance. 

The easy at-home finger-prick blood test for low energy Levels helps identify potential causes of constant lethargy and lack of concentration. It provides information about the levels of Iron, Vitamin D, Blood Sugar, and Thyroid Hormone in the body.

Why Get an Energy Blood Test?

Feeling tired all the time or lacking energy? It may not always be due to a busy lifestyle. Low energy can be caused by poor diet, vitamin deficiency, lack of daily activity, or hormonal imbalance.

What This Energy Test Measures

Thyroid Function
  • TSH, FT3 & FT4 regulate metabolism and energy. Imbalances can lead to chronic fatigue, weight changes, and mood shifts.
Blood Sugar Control

HbA1c shows how your body handles glucose over time. Poor control can cause crashes, fogginess, or low energy.

Iron Levels
  • Iron is essential for transporting oxygen in the blood. Low levels can result in anaemia, weakness, and mental fatigue.
Hormone Health
  • Testosterone supports mood, endurance, strength, and vitality — in both men and women
Vitamin D
  • A vital nutrient for energy regulation, immunity, and mood stability — especially important for those in low-sunlight regions.
