Red blood cells in IDA are usually described as being microcytic (i.e., mean corpuscular volume less than 80 um<sup>3<\/sup> [80 fL]) and hypochromic, however the manifestation of iron deficiency occurs in several stages.<br \/>\n<!--more--><br \/>\nPatients with a serum ferritin concentration less than 25 ng per mL (25 mcg per L) have a very high probability of being iron deficient. The most accurate initial diagnostic test for IDA is the serum ferritin measurement. Serum ferritin values greater than 100 ng per mL (100 mcg per L) indicate adequate iron stores and a low likelihood of IDA. In some populations, such as those with inflammatory disease or cirrhosis, these tests must be interpreted slightly differently because ferritin is an acute-phase reactant. Cutoffs for abnormality in these patients generally are higher.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Diagnosis of Iron Deficiency<\/strong><\/p>\n<table style=\"border-collapse: collapse; width: 100%;\" border=\"1\">\n<tbody>\n<tr>\n<td colspan=\"2\"><strong> Adults with anemia*<\/strong><\/td>\n<td colspan=\"2\"><strong> Adults older than 65<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Test<\/td>\n<td align=\"center\">Likeli-<br \/>\nhood<br \/>\nratio<\/td>\n<td>Test<\/td>\n<td align=\"center\">Likeli-<br \/>\nhood<br \/>\nratio<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\"><strong> Mean corpuscular volume<\/strong><\/td>\n<td colspan=\"2\"><strong> Mean corpuscular volume<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Less than 70 um3 (70 fL)<br \/>\n70 to 74 um3 (74 fL)<br \/>\n75 to 79 um3 (75 to 79 fL)<br \/>\n80 to 84 um3 (80 to 84 fL)<br \/>\n85 to 89 um3 (85 to 89 fL)<br \/>\n90 ?m3 (90 fL) or more<\/td>\n<td align=\"center\">12.5<br \/>\n3.3<br \/>\n1.0<br \/>\n0.91<br \/>\n0.76<br \/>\n0.29<\/td>\n<td>Less than 75 um3<br \/>\n75 to 85 um3<br \/>\n86 to 91 um3 (86 to 91 fL)<br \/>\n92 to 95 um3 (92 to 95 fL)<br \/>\nMore than 95 fL<\/td>\n<td align=\"center\">8.82<br \/>\n1.35<br \/>\n0.64<br \/>\n0.34<br \/>\n0.11<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\"><strong> Ferritin<\/strong><\/td>\n<td colspan=\"2\"><strong> Ferritin<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Less than 15 ng\/mL (15 mcg\/L)<br \/>\n15 to 24 ng\/mL (15 to 24 mcg\/L)<br \/>\n25 to 34 ng\/mL (25 to 34 mcg\/L)<br \/>\n35 to 44 ng\/mL (35 to 44 mcg\/L)<br \/>\n45 to 100 ng\/mL (45 to 100 mcg\/L)<br \/>\nMore than 100 ng\/mL<\/td>\n<td align=\"center\">51.8<br \/>\n8.8<br \/>\n2.5<br \/>\n1.8<br \/>\n0.54<br \/>\n0.08<\/td>\n<td>Less than 19 ng\/mL (19 mcg\/L)<br \/>\n19 to 45 ng\/mL (19 to 45 mcg\/L)<br \/>\n46 to 100 ng\/mL (46 to 100 mcg\/L)<br \/>\nMore than 100 ng\/mL<\/td>\n<td align=\"center\">41.0<br \/>\n3.1<br \/>\n0.46<br \/>\n0.13<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\"><strong> Transferrin saturation<\/strong><\/td>\n<td colspan=\"2\"><strong> Transferrin saturation<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Less than 5 percent<br \/>\n5 to 9 percent<br \/>\n10 to 19 percent<br \/>\n20 to 29 percent<br \/>\n30 to 49 percent<br \/>\n50 percent or more<\/td>\n<td align=\"center\">10.5<br \/>\n2.5<br \/>\n0.81<br \/>\n0.52<br \/>\n0.43<br \/>\n0.15<\/td>\n<td>Less than 5 percent<br \/>\n5 to 8 percent<br \/>\n8 to 21 percent<br \/>\nMore than 21 percent<\/td>\n<td align=\"center\">16.51<br \/>\n1.43<br \/>\n0.57<br \/>\n0.28<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>*Hemoglobin less than 13 g per dL [130 g per L] for men and less than 12 g per dL [120 g per L] for women<\/p>\n<p>&nbsp;<\/p>\n<p><strong>References:<\/strong><\/p>\n<ol>\n<li>Killip S, Bennett JM, Chambers MD.
