Transferrin is a protein that transports iron in the bloodstream and delivers it to cells. Ferritin, on the other hand, is a protein that stores iron in cells, particularly in the liver, spleen, and bone marrow. Essentially, transferrin helps transport iron while ferritin helps store it.

What color tube do I use for transferrin saturation?
You would typically use a lavender-top tube for transferrin saturation testing. This tube contains the anticoagulant EDTA, which is suitable for testing iron-related parameters like transferrin saturation.
Where is ferritin and hemosiderin stored?
Ferritin and hemosiderin are stored in the liver, spleen, and bone marrow. They are primarily stored in the form of ferritin, a complex of iron and protein, with hemosiderin being a breakdown product of ferritin storage.
What is Ferric Pyrophosphate?
Ferric pyrophosphate is a form of iron that is commonly used as a food additive to fortify food products with iron. It is often added to food items like breakfast cereals and infant formula to help address iron deficiency. Consuming ferric pyrophosphate can help improve iron levels in the body and prevent anemia.
What color test tube for ferritin?
A gold or yellow test tube is commonly used for ferritin testing.
What color of tube is used for ferritin?
The color of tube used for ferritin is typically gold or red/gray.
Are transferrin and ferritin stored in bone marrow?
yes
Which of these proteins functions to store or transport iron?
Ferritin is a protein that functions to store iron in the body. Transferrin is a protein that transports iron in the blood.
What tests are used to measure the body's iron levels and storage?
Tests such as serum iron, ferritin, transferrin saturation, and total iron-binding capacity (TIBC) are commonly used to measure the body's iron levels and storage. These tests help diagnose conditions like iron deficiency anemia or iron overload.
What is the transferrin test?
The transferrin test is a direct measurement of transferrin--which is also called siderophilin--levels in the blood.
Do you have to fast for an iron test?
When having a Total iron-binding capacity (TIBC) or transferrin, than it is necessary to avoid eating or drinking for 8 hours before the blood test. It is not necessary to fast when having a ferritin blood test.
What is the medical term meaning iron test?
Typically, measuring the blood iron content would be an iron level. TIBC (total iron binding capacity), transferrin, and ferritin are related tests that are sometimes done when iron levels are in question.
In plasma iron is transported bound to what?
In plasma, iron is transported bound to a protein called transferrin. Transferrin helps to deliver iron to cells throughout the body, where it is necessary for various biological functions.
Is transferrin saturation and iron saturation the same?
Yes, transferrin saturation and iron saturation are the same. Transferrin saturation is a measure of how much iron is bound to transferrin proteins in the blood, expressed as a percentage of total iron-binding capacity. This value reflects the amount of iron available for binding and transport by transferrin.
What color tube do I use for transferrin saturation?
You would typically use a lavender-top tube for transferrin saturation testing. This tube contains the anticoagulant EDTA, which is suitable for testing iron-related parameters like transferrin saturation.
Where is ferritin and hemosiderin stored?
Ferritin and hemosiderin are stored in the liver, spleen, and bone marrow. They are primarily stored in the form of ferritin, a complex of iron and protein, with hemosiderin being a breakdown product of ferritin storage.
What can a bacterium do to respond to high levels of transferrin?
A bacterium can respond to high levels of transferrin by increasing the production of iron-scavenging molecules, such as siderophores, to capture iron from transferrin. Additionally, the bacterium may upregulate iron transporters to increase the uptake of iron from the surrounding environment.
Is a ferritin level of 189 high?
A ferritin level of 189 ng/mL can be considered high. Normal levels can vary between labs, but typically fall between 20-250 ng/mL for women and 20-500 ng/mL for men. Elevated ferritin levels can be due to conditions like iron overload, inflammation, liver disease, or certain cancers. Consulting with a healthcare provider for further evaluation and interpretation is recommended.
