Transferrin Saturation Calculator
- The Transferrin Saturation Calculator is also known as the Transferrin Serum Iron Saturation Calculator.
- Transferrin Saturation Calculator helps you to find the will help to characterize the iron economy of your body.
- Transferrin is a specialized iron carrier protein present in our blood. Each transferrin molecule can carry up to two iron (Fe³⁺) ions.
- The values needed for the estimation are Fe – Serum iron concentration (in µg/dL), TIBC – Total iron binding capacity (in µg/dL), and TF – Serum transferrin concentration (mg/dL).
Steps To Calculate Transferrin Saturation (TSAT) Calculator
- Enter Serum iron (Fe) concentration
- Enter Total iron-binding capacity (TIBC)

What is Transferrin Saturation (TSAT)
- Transferrin Saturation (TSAT) is a medical laboratory value.
- Transferrin saturation measures the amount of iron bound to transferrin, a protein that carries iron in the blood.
- It is the percent of transferrin that has iron bound to it.
- Transferrin Serum Iron Saturation calculator has given here to determine the TSAT value based on the SE and total iron binding capacity.
- TSAT, iron-binding capacity, and saturation can be interchanged where iron-binding capacity shows a patient’s iron status.
- It is calculated by dividing the serum iron level by the total iron binding capacity (TIBC) and multiplying by 100.
Interpretation of Transferrin Saturation Values
Transferrin saturation, measured as a percentage, helps evaluate iron deficiency, anemia, or on the contrary, iron overload (in hemosiderosis, iron poisoning, or hemochromatosis):
- <20% in males, <15% in females – indicates iron deficiency;
- >50% – indicates iron overload or hemochromatosis.

Transferrin Saturation Reference Range
- Transferrin saturations of less than 20% indicate iron deficiency, while transferrin saturations of more than 50% suggest iron overload.
- The terms transferrin saturation and iron-binding capacity, saturation, are interchangeable; however, this value is now most commonly referred to simply as transferrin saturation.
- This minimizes confusion with another value, iron-binding capacity, which is used when determining a patient’s iron status
Normal Range Of Transferrin Saturation
- The normal range for transferrin saturation is 20-50%.
- Males: 15-50%
- Females: 12-45%.

How to Calculate Transferrin Saturation
- To use the calculator, simply plug in your values for serum iron and TIBC.
- For example, if your serum iron level is 50 mcg/dL and your TIBC is 300 mcg/dL, your transferrin saturation would be calculated as follows:
Transferrin Saturation = FE / TIBC = (50 mcg/dL / 300 mcg/dL) * 100 = 16.7%
Low Transferrin Saturation Symptoms
A person with a low iron saturation in the blood may experience various symptoms of iron deficiency.
- Pale skin
- Brittle nails or spooning of the nails
- Swollen or sore tongue
- Chest pain
- Poor concentration
- Tiredness
- Headaches
- Dizziness
- Shortness of breath
- Weakness
- Heart palpitations
- Hair loss
- Trusted Source
- Restless legs
- Unusual cravings for nonfood items, such as ice or paint
Risk factors for low iron saturation
Here are risk factors which can include low iron saturation or iron deficiency anemia
- Age: Infants, young children, pregnant people, and those approaching menopause have an increased risk.
- Genetics: Certain bleeding disorders, such as Von Willebrand’s disease, affect the blood’s ability to clot.
- Lifestyle factors: These include eating a vegetarian or vegan diet, eating a diet low in iron-rich foods, and undergoing frequent blood tests or donations.
- Hormonal changes: People who experience heavy menstruation have a higher risk of becoming anemic. The risk also increases during pregnancy for individual patient care.
Decreased transferrin saturation can be caused by following
- Iron-poor diet (e.g., vegan)
- Impaired iron absorption (e.g., celiac disease)
- Pregnancy and lactation
- Hormonal contraceptives
- Chronic blood loss (e.g., colon cancer)
Increased transferrin saturation can be caused by following
- Iron-rich diet
- Iron supplements
- Increased iron absorption (e.g., primary hemochromatosis)
- Repeated blood transfusions
- Iron binding capacity
Test For Transferrin Saturation
- A complete blood count: This blood test reveals the blood cell count, the hemoglobin level, the hematocrit level, and the mean corpuscular volume.
- Serum iron test: This test measures the amount of iron in the blood. The level of iron may indicate whether a person has a low iron saturation level.
- Peripheral smear: This test involves looking at the red blood cells under a microscope to see whether they appear smaller and paler than usual.
- Transferrin or TIBC test: This test will measure the amount of transferrin in the blood.
Prevention
A person can take steps to prevent low iron saturation levels.
- Meat and poultry
- Seafood
- Leafy green vegetables, such as broccoli and kale
- Legumes, such as pinto beans and black-eyed peas
- Iron-enriched pasta, grains, rice, and cereals
