Reference ranges are population averages. Being within range doesn't mean a value is optimal for you — especially when symptoms are present.
Ferritin vs serum iron, free T3 and T4 vs TSH alone, fasting insulin, cortisol pattern, vitamin D, B12 — tests that are frequently missed.
A single result tells you where you are. A trend tells you which direction you're moving. Most patients have never seen their results interpreted over time.
Thyroid, iron, B12, vitamin D, cortisol, sleep apnoea, insulin resistance, and low testosterone or oestrogen — the clinical checklist for unexplained fatigue.
What the evidence says about thyroid function, inflammation markers, blood sugar variability, and sleep quality as contributors.
Which investigations are genuinely worth pursuing and what a clinical review can clarify.
