Part Descriptions

LP15677-5   Iron
Iron homeostasis diseases are common and may be attributed to iron deficiency or iron overload. Iron deficiency may be due to increased loss or inadequate absorption. Iron overload occurs when the erythropoiesis is normal, but the iron exceeds the iron binding capacity of transferrin. Iron overload may also occur when catabolism of red cells occurs. Iron levels are used to help diagnose specific types of anemia. Iron levels are low in iron deficiency anemia and anemia of chronic disease. Iron levels are normal to increased in sideroblastic anemia and increased in hemolytic anemias,hemochromatosis, and acute liver disease. Normal to decreased iron levels are seen with protein depletion. Other tests used as iron status indicators include ferritin, transferrin, TIBC, and iron saturation.(Jacobs and DeMott Laboratory Test Handbook, 5th edition, DS Jacobs, WR DeMott and DK Oxley, 2001.)

In veterinary toxicology, one of the best known types of iron poisoning is in young piglets infected with an iron dextran preparation for the prevention of postnatal anemia. However, iron intoxication can also occur in other animal species. Source: Regenstrief LOINC

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
