Each transferrin molecule has two iron-binding sites (N-terminal and C-terminal) and can therefore transport two iron ions simultaneously - it normally circulates charged to 20-45 % of its total capacity (normal saturation), with most of its sites remaining available to capture any additional iron absorbed or released. Hepatic transferrin synthesis is regulated inversely to iron stores: when iron stores decrease \u2192 the liver increases transferrin production (to maximize capture of the little iron available) \u2192 high transferrin + low saturation + and conversely when iron stores are high \u2192 reduced transferrin production \u2192 low or normal transferrin + high saturation. This inverse relationship between iron stores and transferrin is central to the interpretation of martial status. Transferrin is also a negative acute-phase reactant (like albumin): it decreases in chronic inflammatory states + liver disease + malnutrition + independently of iron status - which can complicate the interpretation of the martial status in contexts of chronic inflammation. Transferrin saturation (ratio of serum iron to CTF \u00d7 100) is the most important calculated parameter of martial status, as it directly reflects the availability of iron to tissues.\n <\/div>\n\n <h2>Martial Balance Settings and Their Relationships<\/h2>\n <ul class=\"co-list\">\n <li><strong>Serum iron (sideremia):<\/strong> transferrin-bound circulating iron concentration + normal: 10\u201330 \u00b5mol\/L + highly variable depending on meals + stress + time of collection (significant circadian variations \u2014 maximum in the morning) \u2192 collect in the morning after fasting + unreliable marker on its own<\/li>\n <li><strong>Serum transferrin<\/strong> Transferrin concentration + normal: 2.0\u20133.5 g\/L + increased in iron deficiency + decreased in inflammation + liver disease + malnutrition + iron overload<\/li>\n <li><strong>TIBC (Total Iron-Binding Capacity):<\/strong> CTF = maximum iron binding capacity + calculated or measured + CTF = transferrin (g\/L) x 25 (approximately) + normal: 45-70 \u00b5mol\/L + increased if transferrin is high (iron deficiency) + decreased if transferrin is low (inflammation + liver disease)<\/li>\n <li><strong>Transferrin saturation (Tsat):<\/strong> Tsat = (serum iron \/ TIBC) \u00d7 100 + normal: 20\u201345 %+ low (45\u201350 % ) = iron overload (hemochromatosis) + the most informative parameter of the iron panel<\/li>\n <li><strong>Serum ferritin:<\/strong> reflects the iron reserves of the reticuloendothelial system + normal: 15\u2013300 \u00b5g\/L + low (300\u2013400 \u00b5g\/L) = overload + or inflammation + or liver disease + or metabolic syndrome + ferritin is a positive acute phase reactant \u2192 can be falsely normal or elevated despite deficiency if there is concomitant inflammation<\/li>\n <\/ul>\n\n <h2>Combined interpretation \u2014 common diagnostics<\/h2>\n\n <table class=\"co-table\">\n <thead>\n <tr>\n <th>Diagnosis<\/th>\n <th>Ferritin<\/th>\n <th>Serum iron<\/th>\n <th>Transferrin \/ CTF<\/th>\n <th>Saturation Temperature<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Iron deficiency (iron-deficiency anemia)<\/td>\n <td>Low (<15 \u00b5g\/L)<\/td>\n <td>Low<\/td>\n <td>Elevated (hepatic compensation)<\/td>\n <td>Low (<20 %)<\/td>\n <\/tr>\n <tr>\n <td>Anemia of chronic disease (ACD)<\/td>\n <td>Normal or high (acute phase reactant)<\/td>\n <td>Low<\/td>\n <td>Low or normal (negative reactant)<\/td>\n <td>Low or normal low<\/td>\n <\/tr>\n <tr>\n <td>Deficiency + concomitant inflammation<\/td>\n <td>Variable (can be normal despite deficiency)<\/td>\n <td>Low<\/td>\n <td>Variable<\/td>\n <td>Low (<20 %)<\/td>\n <\/tr>\n <tr>\n <td>Hereditary hemochromatosis (HFE)<\/td>\n <td>Very high (>300\u20131000 \u00b5g\/L)<\/td>\n <td>Raised<\/td>\n <td>Low or normal<\/td>\n <td>Very high (>45\u201360 %)<\/td>\n <\/tr>\n <tr>\n <td>Iron overload<\/td>\n <td>Very high<\/td>\n <td>Raised<\/td>\n <td>Low<\/td>\n <td>Very high<\/td>\n <\/tr>\n <tr>\n <td>Liver disease (cirrhosis)<\/td>\n <td>Variable (elevated by cytolysis)<\/td>\n <td>Variable<\/td>\n <td>Basse (reduced hepatic synthesis)<\/td>\n <td>Elevated (low transferrin \u2192 falsely high saturation)<\/td>\n <\/tr>\n <tr>\n <td>Pregnancy (2nd\u20133rd trimester)<\/td>\n <td>Bass (increased needs)<\/td>\n <td>Low<\/td>\n <td>Elevated (increased needs)<\/td>\n <td>Low<\/td>\n <\/tr>\n <tr>\n <td>Normal<\/td>\n <td>15\u2013300 \u00b5g\/L<\/td>\n <td>10\u201330 micromoles per liter<\/td>\n <td>2.0\u20133.5 g\/L (CTF 45\u201370 \u00b5mol\/L)<\/td>\n <td>20\u201345 %<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n\n <h2>Transferrin and hereditary hemochromatosis<\/h2>\n <ul class=\"co-list\">\n <li><strong>Hemochromatosis screening:<\/strong> saturation de la transferrine \u00e0 jeun > 45 % (femme) ou > 50 % (homme) = seuil d'alerte \u2192 indication de test g\u00e9n\u00e9tique HFE (mutations C282Y + H63D) \u2192 si C282Y homozygote confirm\u00e9 \u2192 ferritine pour \u00e9valuer le degr\u00e9 de surcharge \u2192 biopsie h\u00e9patique si ferritine > 1 000 \u00b5g\/L ou transaminases \u00e9lev\u00e9es (\u00e9valuation de la fibrose)<\/li>\n <li><strong>Meaning of a high Tsat:<\/strong> transferrin saturation is the most sensitive screening test for hemochromatosis (sensitivity 90-95%%if Tsat > 45%%) + but false positives are possible (alcoholic liver disease + MASLD + hemolytic anemia + postprandial sample)<\/li>\n <li><strong>Treatment of hemochromatosis:<\/strong> therapeutic phlebotomy (bloodletting) \u2192 target ferritin < 50 \u00b5g\/L + transferrin saturation < 50% % \u2192 follow-up with ferritin + CBC + Tsat every 2\u20134 months<\/li>\n <\/ul>\n\n <h2>Transferrin and Anemia of Chronic Disease (ACD) vs Iron Deficiency<\/h2>\n <ul class=\"co-list\">\n <li><strong>Common clinical problem:<\/strong> Distinguishing true iron deficiency from anemia of chronic disease (in the context of chronic inflammation -

Each transferrin molecule has two iron-binding sites (N-terminal and C-terminal) and can therefore transport two iron ions simultaneously - it normally circulates charged to 20-45 % of its total capacity (normal saturation), with most of its sites remaining available to capture any additional iron absorbed or released. Hepatic transferrin synthesis is regulated inversely to iron stores: when iron stores decrease \u2192 the liver increases transferrin production (to maximize capture of the little iron available) \u2192 high transferrin + low saturation + and conversely when iron stores are high \u2192 reduced transferrin production \u2192 low or normal transferrin + high saturation. This inverse relationship between iron stores and transferrin is central to the interpretation of martial status. Transferrin is also a negative acute-phase reactant (like albumin): it decreases in chronic inflammatory states + liver disease + malnutrition + independently of iron status - which can complicate the interpretation of the martial status in contexts of chronic inflammation. Transferrin saturation (ratio of serum iron to CTF \u00d7 100) is the most important calculated parameter of martial status, as it directly reflects the availability of iron to tissues.\n <\/div>\n\n <h2>Martial Balance Settings and Their Relationships<\/h2>\n <ul class=\"co-list\">\n <li><strong>Serum iron (sideremia):<\/strong> transferrin-bound circulating iron concentration + normal: 10\u201330 \u00b5mol\/L + highly variable depending on meals + stress + time of collection (significant circadian variations \u2014 maximum in the morning) \u2192 collect in the morning after fasting + unreliable marker on its own<\/li>\n <li><strong>Serum transferrin<\/strong> Transferrin concentration + normal: 2.0\u20133.5 g\/L + increased in iron deficiency + decreased in inflammation + liver disease + malnutrition + iron overload<\/li>\n <li><strong>TIBC (Total Iron-Binding Capacity):<\/strong> CTF = maximum iron binding capacity + calculated or measured + CTF = transferrin (g\/L) x 25 (approximately) + normal: 45-70 \u00b5mol\/L + increased if transferrin is high (iron deficiency) + decreased if transferrin is low (inflammation + liver disease)<\/li>\n <li><strong>Transferrin saturation (Tsat):<\/strong> Tsat = (serum iron \/ TIBC) \u00d7 100 + normal: 20\u201345 %+ low (45\u201350 % ) = iron overload (hemochromatosis) + the most informative parameter of the iron panel<\/li>\n <li><strong>Serum ferritin:<\/strong> reflects the iron reserves of the reticuloendothelial system + normal: 15\u2013300 \u00b5g\/L + low (300\u2013400 \u00b5g\/L) = overload + or inflammation + or liver disease + or metabolic syndrome + ferritin is a positive acute phase reactant \u2192 can be falsely normal or elevated despite deficiency if there is concomitant inflammation<\/li>\n <\/ul>\n\n <h2>Combined interpretation \u2014 common diagnostics<\/h2>\n\n <table class=\"co-table\">\n <thead>\n <tr>\n <th>Diagnosis<\/th>\n <th>Ferritin<\/th>\n <th>Serum iron<\/th>\n <th>Transferrin \/ CTF<\/th>\n <th>Saturation Temperature<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Iron deficiency (iron-deficiency anemia)<\/td>\n <td>Low (<15 \u00b5g\/L)<\/td>\n <td>Low<\/td>\n <td>Elevated (hepatic compensation)<\/td>\n <td>Low (<20 %)<\/td>\n <\/tr>\n <tr>\n <td>Anemia of chronic disease (ACD)<\/td>\n <td>Normal or high (acute phase reactant)<\/td>\n <td>Low<\/td>\n <td>Low or normal (negative reactant)<\/td>\n <td>Low or normal low<\/td>\n <\/tr>\n <tr>\n <td>Deficiency + concomitant inflammation<\/td>\n <td>Variable (can be normal despite deficiency)<\/td>\n <td>Low<\/td>\n <td>Variable<\/td>\n <td>Low (<20 %)<\/td>\n <\/tr>\n <tr>\n <td>Hereditary hemochromatosis (HFE)<\/td>\n <td>Very high (>300\u20131000 \u00b5g\/L)<\/td>\n <td>Raised<\/td>\n <td>Low or normal<\/td>\n <td>Very high (>45\u201360 %)<\/td>\n <\/tr>\n <tr>\n <td>Iron overload<\/td>\n <td>Very high<\/td>\n <td>Raised<\/td>\n <td>Low<\/td>\n <td>Very high<\/td>\n <\/tr>\n <tr>\n <td>Liver disease (cirrhosis)<\/td>\n <td>Variable (elevated by cytolysis)<\/td>\n <td>Variable<\/td>\n <td>Basse (reduced hepatic synthesis)<\/td>\n <td>Elevated (low transferrin \u2192 falsely high saturation)<\/td>\n <\/tr>\n <tr>\n <td>Pregnancy (2nd\u20133rd trimester)<\/td>\n <td>Bass (increased needs)<\/td>\n <td>Low<\/td>\n <td>Elevated (increased needs)<\/td>\n <td>Low<\/td>\n <\/tr>\n <tr>\n <td>Normal<\/td>\n <td>15\u2013300 \u00b5g\/L<\/td>\n <td>10\u201330 micromoles per liter<\/td>\n <td>2.0\u20133.5 g\/L (CTF 45\u201370 \u00b5mol\/L)<\/td>\n <td>20\u201345 %<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n\n <h2>Transferrin and hereditary hemochromatosis<\/h2>\n <ul class=\"co-list\">\n <li><strong>Hemochromatosis screening:<\/strong> saturation de la transferrine \u00e0 jeun > 45 % (femme) ou > 50 % (homme) = seuil d'alerte \u2192 indication de test g\u00e9n\u00e9tique HFE (mutations C282Y + H63D) \u2192 si C282Y homozygote confirm\u00e9 \u2192 ferritine pour \u00e9valuer le degr\u00e9 de surcharge \u2192 biopsie h\u00e9patique si ferritine > 1 000 \u00b5g\/L ou transaminases \u00e9lev\u00e9es (\u00e9valuation de la fibrose)<\/li>\n <li><strong>Meaning of a high Tsat:<\/strong> transferrin saturation is the most sensitive screening test for hemochromatosis (sensitivity 90-95%%if Tsat > 45%%) + but false positives are possible (alcoholic liver disease + MASLD + hemolytic anemia + postprandial sample)<\/li>\n <li><strong>Treatment of hemochromatosis:<\/strong> therapeutic phlebotomy (bloodletting) \u2192 target ferritin < 50 \u00b5g\/L + transferrin saturation < 50% % \u2192 follow-up with ferritin + CBC + Tsat every 2\u20134 months<\/li>\n <\/ul>\n\n <h2>Transferrin and Anemia of Chronic Disease (ACD) vs Iron Deficiency<\/h2>\n <ul class=\"co-list\">\n <li><strong>Common clinical problem:<\/strong> Distinguishing true iron deficiency from anemia of chronic disease (in the context of chronic inflammation -
