A single ferritin blood test checking iron stores, aimed at people with symptoms of tiredness or at higher risk of iron deficiency, such as those on plant-based diets or with heavy periods.
1 biomarker as listed by Selph.
The Iron Deficiency Blood Test measures ferritin, the body's iron storage protein, which is the standard first test for iron deficiency. A low ferritin result generally indicates depleted iron stores, though Selph's Advanced Iron Test adds three further markers if you need help interpreting a borderline result.
Against the five ferritin tests we track, its £49 price is about 15% above the £42.63 median. Medichecks' Ferritin Blood Test (£39) and Forth's Ferritin Home Blood Test Kit (£41) cover the same single marker for less, and MyHealthChecked's rapid ferritin test costs just £8, though as a rapid-format test it differs from a lab-processed sample.
value for money is correspondingly modest, while Collection Convenience and Trust Signals score highly, reflecting the choice of finger-prick, Tasso EasyDraw, clinic or nurse draw and doctor review of every result within 1 to 2 days.
This suits you if you want a quick, lab-based ferritin check with flexible collection options, for example if you are on a plant-based diet or have heavy periods. If price is the priority, Medichecks' Ferritin Blood Test (£39) or Forth's Ferritin Home Blood Test Kit (£41) test the same marker for less, and if you need more detail on a low result, Selph's own Advanced Iron Test adds three further markers for £55.
You can collect a sample at home with a finger-prick kit included in the price, or pay more for the Tasso EasyDraw device, a clinic visit or a nurse draw at home or work; a self-arranged venous draw is also included. A Selph doctor reviews your ferritin result and provides a written report, typically within 1 to 2 days.
This ferritin test costs £49, about 15% above the £42.63 median for the five ferritin tests we track. Medichecks' Ferritin Blood Test (£39) and Forth's Ferritin Home Blood Test Kit (£41) test the same single marker for less, while MyHealthChecked's rapid ferritin test costs just £8. The main advantage of this version is the choice of four collection methods and a 1 to 2 day turnaround.

Ferritin test priced within 4% of the market rate
A single blood test measuring ferritin, the protein that reflects how much iron your body has stored. It suits people checking for possible iron deficiency or iron overload rather than needing a full health screen.
Mid-priced ferritin test, not the cheapest available
A single-marker finger-prick test measuring ferritin, commonly used to assess the body's iron stores, suited to anyone with symptoms of possible iron deficiency such as fatigue or hair loss.
Cheapest ferritin test in its group, by far
A rapid finger-prick test for ferritin (iron stores), giving a result in minutes to flag possible iron deficiency. Suits anyone with symptoms like fatigue or breathlessness who wants a quick first check.
Priciest ferritin test among the peers we compare it with
A single ferritin blood test used to check the body's iron stores, relevant to fatigue, anaemia and general iron balance.
Iron Self-Test is an easy-to-use ferritin at-home test. Ferritin is a blood protein that stores iron within the cells. Ferritin tests are commonly used by doctors to understand how much iron your body stores.
