Transferrin Saturation Meaning
Transferrin saturation is calculated from the iron value and the transferrin value. It is a measure of the percentage of transferrin that is saturated with iron. Low transferrin saturation may indicate iron deficiency.
Transferrin Saturation Values in Men and Women: Detailed Explanation
Here you will find an overview of transferrin saturation values for men and women, giving you insight into when your transferrin saturation is normal, low, or high.
Transferrin Saturation Values in Men and Women: Detailed Explanation
- Normal: A transferrin saturation value between 16.8 and 42.75% is considered normal. This indicates a good balance in the amount of iron transported in the blood via transferrin.
- Low: A transferrin saturation value below 16% is considered abnormal and too low. This may indicate reduced iron transport capacity or iron deficiency. Values between 16 and 16.8% are considered “cautionary,” meaning that the saturation is at the lower limit of normal and further monitoring may be necessary.
- High: A transferrin saturation value above 42.75% is on the high side of normal values. Values between 42.75 and 45% are considered “caution,” meaning that the saturation is at the upper limit of normal. If the value exceeds 45%, it is considered abnormal and too high, which may indicate increased iron absorption or iron accumulation in the body. Further interpretation is then necessary, in combination with other values from the iron spectrum.
Transferrin Saturation Values in Men and Women: Detailed Explanation
| Result | Unit | Value min-max | Age | Gender | Biomarker interpretation |
|---|---|---|---|---|---|
| Deviant | % | 0 - 16 | 18 - 100 | Man & Woman | The transferrin saturation is outside the normal range and is too low. The interpretation depends on the other values in the iron spectrum. |
| Caution | % | 16 - 16.8 | 18 - 100 | Man & Woman | The transferrin saturation is still within normal values, but is on the low side. |
| Normal | % | 16.8 - 42.75 | 18 - 100 | Man & Woman | The transferrin saturation is good. |
| Caution | % | 42.75 - 45 | 18 - 100 | Man & Woman | The transferrin saturation is still within normal values, but is on the high side. |
| Deviant | % | 45 - 100 | 18 - 100 | Man & Woman | The transferrin saturation is outside normal values and is too high. The interpretation depends on the other values in the iron spectrum. |
This will help you better understand what a healthy transferrin saturation value is and when
your values may deviate, which could indicate underlying health issues.
