Deep Sleep & Fatigue Investigation Panel

The Nuvivo Deep Sleep & Fatigue Investigation Panel is designed to uncover hidden factors that may be affecting your ability to rest, recharge, and stay energised throughout the day. This panel investigates key hormones, vitamins, and metabolic markers that influence sleep quality, mood, and overall energy. Whether you're feeling persistently tired, struggling to fall asleep, or waking up unrefreshed, this test provides insight into the root causes.

Who is this test for?

• Individuals experiencing chronic fatigue, poor sleep, or frequent low energy

• People struggling with brain fog, mood changes, or low motivation

• Those with suspected nutrient deficiencies or hormonal imbalances

• Anyone looking to improve sleep patterns, reduce stress, and support daily energy

What’s tested?

Hormonal & Sleep Regulation:

• Thyroid Function (TSH, Free T4):
  Assesses thyroid hormone levels that support metabolism, energy regulation, and restful sleep

• Cortisol:
  The body’s main stress hormone, influencing the sleep-wake cycle, energy levels, and recovery

Nutrient & Energy Markers:

• Iron Studies (Iron, Ferritin, TIBC):
  Evaluates iron status, essential for oxygen transport, energy production, and mental clarity

• Vitamin D:
  Supports immune function, mood stability, and sleep quality

• Vitamin B12:
  Important for red blood cell formation and nervous system function — impacting focus, energy, and mood

Blood Sugar & Metabolic Health:

• HbA1c (Glycated Haemoglobin):
  Reflects long-term blood sugar control, which can influence energy fluctuations and overall metabolic health
