The Transferrin Saturation is included in test packages, which you can buy at a lower price.

Iron (transferrin) % saturation is calculated by an equation using plasma iron and transferrin. TIBC is a calculated parameter derived from the transferrin plasma concentration. In hereditary hemochromatosis, serum iron is usually > 150 μg/dL and iron (transferrin) saturation is greater than 60%.

Purpose of the test

The Transferrin Saturation test determines an individual's iron status by using the ratio of serum iron concentration to the total iron binding capacity (TIBC) as a percentage. This test provides insights into how much iron in the blood is bound to transferrin, a glycoprotein responsible for transporting iron around the body. The percentage of transferrin saturation can increase or decrease based on the body's iron status, making it a valuable metric for assessing iron-related conditions.

Who Should Get Tested

Individuals displaying symptoms of iron deficiency anaemia or haemochromatosis (iron overload) should consider this test. Symptoms of iron deficiency include tiredness, pale skin, shortness of breath, and heart palpitations. On the other hand, haemochromatosis can manifest as fatigue, joint pain, stomach pain, liver damage, and other related symptoms.

Preparing for the Test
Fasting
icon
Depending on the type of cholesterol test, you may be required to fast for 9 to 12 hours before the test. This means avoiding all food and drinks except water. Fasting is usually required for a lipid panel, which measures LDL and HDL cholesterol, and triglycerides.
Medications
icon
Inform your healthcare provider about any medications you are currently taking, including over-the-counter medications and supplements, as they can affect your test results.
Alcohol
icon
Avoid alcohol consumption for at least 24 hours before the test, as alcohol can raise triglyceride levels.
Exercise
icon
Avoid heavy exercise for 24 hours before the test, as this can also affect cholesterol and triglyceride levels.
Smoking
icon
Avoid smoking or using any nicotine products for at least 30 minutes before the test, as they can temporarily increase cholesterol levels.
Follow instructions
icon
Follow any specific instructions provided by your healthcare provider, such as the time of day to take the test or any dietary restrictions.
Interpreting Test Results

The test results will show the percentage of transferrin saturation, indicating how much serum iron is bound to transferrin. A low percentage often signifies iron deficiency, while a high percentage can confirm conditions like haemochromatosis. Understanding these results can help diagnose various health conditions related to iron metabolism and guide appropriate interventions or treatments.
