Iron Profile Test vs Ferritin Test

Understanding Your True Iron Status Book an Iron Assessment

Feeling Tired, Breathless or Struggling to Concentrate?

Feeling tired, breathless, struggling to concentrate, or noticing hair thinning?Many people assume they simply need more iron, but the reality is often more complex.A standard ferritin blood test provides useful information, but it only tells part of the story. To truly understand your iron status, a comprehensive iron profile test is often required.At Levitas DX, we regularly see patients who have normal ferritin levels yet continue to experience symptoms of iron deficiency.

Why Iron Alone Isn’t Always Enough

Ferritin is a protein that stores iron within the body. A ferritin blood test measures these stored reserves and is often the first investigation requested when iron deficiency is suspected.However, ferritin is also an inflammatory marker.

Important: Ferritin can appear normal or elevated even when functional iron deficiency exists.

  • Chronic inflammation
  • Infection
  • Metabolic dysfunction
  • Autoimmune conditions
  • Long-term health issues

What Does a Full Iron Panel Measure?

Ferritin

Measures stored iron reserves.

Serum Iron

Measures circulating iron in the bloodstream.

Transferrin

Iron transport protein.

TSAT

Measures percentage of transferrin carrying iron.

TIBC

Measures iron binding capacity.

Why Accurate Iron Testing Matters

Iron deficiency is one of the most common nutritional deficiencies worldwide, yet it remains frequently overlooked or incompletely assessed.Understanding your ferritin level is important, but understanding how your body stores, transports, and utilises iron provides a much clearer picture of your health. A complete iron profile test, including a TIBC test, can help identify issues earlier and guide more personalised treatment strategies.

Bone Profile Blood Test in London, Surrey & UK-Wide: Spot the Silent Risk Early Levitas Group | MSK & Diagnostics

Bones rarely complain until something breaks. Osteoporosis and osteopaenia are silent — no symptoms, just gradual loss of strength. A simple bone profile blood test, with bone density scanning where needed, is one of the most useful checks you can do to stay ahead. A small blood panel covering calcium, phosphate, alkaline phosphatase, albumin, vitamin D, and parathyroid hormone (PTH). Together they show whether bone is being built, broken down, or under stress from vitamin D deficiency, hormone changes, or an overactive parathyroid gland. Picks up early osteopaenia and osteoporosis, before a fracture Safely monitors high-dose vitamin D so you’re optimised, not over-corrected Checks parathyroid activity, which can quietly drain calcium from bone Flags hormone links — menopause, low testosterone, and thyroid all influence boneBeyond the blood test, we offer DXA bone density and fragility scanning, near-patient testing for same-day results, remote blood testing UK-wide, and hormone and metabolic review. Our clinicians treat the whole person — history, hormones, movement, goals — not a number on a page.A private bone profile blood test in London typically starts from around £60–£90.
