A small retrospective analysis of HD patients found providing iron to patients to target TSAT > 30% unless ferritin levels were > 1,200 ng/ml decreased ESA requirements but did not significantly increase infectious complications. 19 A number of new studies have been published since the KDIGO guidelines were developed. 18 In the CHOIR study the patients treated to a target Hb level of 13.5 g/dL had a higher risk of adverse events with no improvement in quality of life. 7 In the study, TSAT, ferritin, sTfR, and CRP were not good predictors of response to anemia treatment. The Dialysis Patients' Response to IV Iron with Elevated Ferritin (DRIVE) study found that providing IV iron with a concomitant increase in ESA dose to patients with high ferritin (500-1,200 ng/ml) and low TSAT levels (≤ 25%) increased hemoglobin levels in the short term. At that time, they found insufficient evidence to recommend IV iron when ferritin > 500 ng/mL. Patients with absolute iron deficiency have insufficient iron stores to meet the erythropoietic demand, commonly defined as serum ferritin 200 ng/mL and TSAT > 20%. But increasingly, we face the clinical scenario of high serum ferritin > 800 ng/ml, implying iron overload and low TSAT 800 ng/ml. We have relied on the use of serum ferritin and transferrin saturation (TSAT) to guide iron therapy. Further, once the results of the tests are received, what level constitutes iron deficiency in patients with end-stage renal disease and indicates a need for an adjustment in treatment? But which of these tests are most useful? Both the presence of storage iron and the availability of iron to support ongoing erythropoiesis must be determined. Iron status can be assessed by a wide range of tests, blood tests and more invasive procedures. If you continue to have this issue please contact to HealioĪccurate assessment of iron status is critical to prescribing treatments for anemia in chronic kidney disease and assessing the effectiveness of those treatments. Ordered by any health professional during this period.We were unable to process your request. Data obtained from the Laboratory claims collection. The percentage of ferritin only and iron studies tests performed nationally and at sample Of ferritin only and iron studies tests that were performed nationally and for your practice population over the lastįigure 1. Figure 1 below shows the breakdown of anaemia testing as a percentage Proportion of these that are ferritin only tests has increased from 53% in 2010 to 68% of tests in 2013. Although the total number of tests to investigate anaemia have risen in New Zealand over the last four years, the.Testing for iron deficiency anaemia – Encouraging results! If serumįerritin is increased (iron deficiency is unlikely with ferritin levels over 100 micrograms/L), iron studies may be requested Iron studies may be indicated if iron overload is suspected, or other comorbidities are known or suspected.(serum iron, iron binding capacity and serum transferrin) should not be ordered as initial first-line tests. Serum ferritin alone is a highly sensitive test of iron deficiency in patients with otherwise good health.Patients with uncomplicated iron deficiency can be given a trial treatment with oral iron supplementation to correctĪnaemia and replenish physiological storesįerritin should be used to investigate suspected iron deficiency anaemia 3.Review and correct any dietary factors patients diagnosed with coeliac disease should begin a gluten free diet.If appropriate, prevent further blood loss by treating the underlying cause, e.g.Gastric erosions/ulcerations and those that interfere with coagulation/platelet function, dietary deficiency (e.g. menorrhagia or pregnancy), gastrointestinal bleeding, malabsorption (e.g. The cause of iron deficiency anaemia always needs to be investigated, some of the primary causes are: obstetric/gynaecological.The most frequent cause of microcytic anaemia in New Zealand is iron deficiency.Microcytic anaemia is defined as a mean cell volume In this article View / Download pdf version of this article Practical tips and information for investigating iron deficiency anaemia 1,2 Testing for iron deficiency anaemia – Encouraging results!.Ferritin should be used to investigate suspected iron deficiency anaemia.Practical tips and information for investigating iron deficiency anaemia.
