home?\u003c\/summary\u003e\n\u003cp\u003eYes. This kit uses a capillary blood sample collected at home and returned for laboratory analysis. It measures five iron related markers rather than providing an instant home reading.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does a full iron profile blood test check?\u003c\/summary\u003e\n\u003cp\u003eThis panel checks ferritin, serum iron, transferrin, total iron binding capacity and transferrin saturation.

The profile can support assessment of iron status but cannot diagnose anaemia by itself.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between iron and ferritin?\u003c\/summary\u003e\n\u003cp\u003eSerum iron measures iron circulating at the time of collection and can vary with meals and time of day. Ferritin is the main marker used to estimate stored iron, although inflammation and liver conditions can raise it.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat ferritin level suggests iron deficiency in the UK?\u003c\/summary\u003e\n\u003cp\u003eNICE guidance states that ferritin below 30 micrograms per litre confirms iron deficiency in adults. A higher ferritin does not always exclude deficiency where inflammation or chronic illness is present.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is transferrin saturation?\u003c\/summary\u003e\n\u003cp\u003eTransferrin saturation estimates the percentage of transferrin iron binding sites that are occupied. It is calculated from serum iron and TIBC and can help assess possible deficiency or iron overload.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is transferrin?\u003c\/summary\u003e\n\u003cp\u003eTransferrin is the main protein that transports iron through the blood. It may rise when iron stores are low and may fall with inflammation, liver disease, poor nutrition or iron overload.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is TIBC?\u003c\/summary\u003e\n\u003cp\u003eTotal iron binding capacity estimates the total amount of iron that blood proteins could bind and transport. TIBC is often higher in iron deficiency and lower or normal in inflammation or iron overload.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is UIBC?\u003c\/summary\u003e\n\u003cp\u003eUnsaturated iron binding capacity estimates the unused iron binding capacity. Some laboratories calculate TIBC from serum iron plus UIBC, but UIBC may not be reported separately on every result.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need to fast for an iron blood test?\u003c\/summary\u003e\n\u003cp\u003eFollow the kit instruction to fast for 12 hours with plain water only. Serum iron and transferrin saturation can vary with meals and time of day, so a morning fasting sample improves consistency.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eShould I stop iron supplements before testing?\u003c\/summary\u003e\n\u003cp\u003eFollow the kit instruction for non prescribed iron products. Do not stop prescribed iron, injections or infusions without medical advice. Record the dose and timing because supplementation can affect the result.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan biotin affect an iron test?\u003c\/summary\u003e\n\u003cp\u003eHigh dose biotin, which is vitamin B7, can interfere with some laboratory immunoassays. Follow the kit guidance and ask a clinician before stopping prescribed biotin.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan the contraceptive pill affect iron results?\u003c\/summary\u003e\n\u003cp\u003eOestrogen containing contraception can alter transferrin and iron binding capacity. Record the exact contraceptive or hormone treatment so the result can be interpreted in context.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan inflammation affect ferritin?\u003c\/summary\u003e\n\u003cp\u003eYes. Ferritin is an acute phase protein and may rise with infection, inflammation, liver disease, obesity or other conditions. A normal or high ferritin can therefore sometimes mask iron deficiency.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan a high ferritin result mean haemochromatosis?\u003c\/summary\u003e\n\u003cp\u003ePossibly, but high ferritin alone does not diagnose iron overload. Persistent raised transferrin saturation together with raised ferritin may prompt liver tests, repeat fasting iron studies and HFE genetic testing.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan a normal serum iron result rule out iron deficiency?\u003c\/summary\u003e\n\u003cp\u003eNo. Serum iron changes during the day and after meals and does not reflect stored iron reliably. Ferritin and the complete pattern are more informative.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWho may be at risk of low iron stores?\u003c\/summary\u003e\n\u003cp\u003eRisk can be higher with heavy menstrual bleeding, pregnancy, blood donation, gastrointestinal blood loss, restrictive diets, malabsorption, bariatric surgery, inflammatory disease and increased physiological requirements.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat symptoms can occur with low iron or anaemia?\u003c\/summary\u003e\n\u003cp\u003ePossible symptoms include tiredness, weakness, breathlessness, palpitations, headaches, pale skin, reduced exercise tolerance and restless legs.
