This test is ideal if you're experiencing constant fatigue, weakness, or feeling tired all the time despite getting enough sleep. It helps identify iron deficiency or iron overload by measuring transferrin, a protein that carries iron in your blood. Many people use this test when they suspect their exhaustion is related to iron imbalance or nutritional issues but want concrete answers.
You'll need to fast for at least 12 hours before your blood draw. This means no food or beverages except water during that time. Fasting ensures accurate transferrin measurements since food intake can temporarily affect iron-related biomarkers. Schedule your test for the morning if possible, so you can fast overnight while you sleep.
This test measures Transferrin, a key protein that binds to iron and transports it throughout your body. By checking transferrin levels, we can assess your iron balance and nutritional status, which directly impacts your energy, immune function, and overall vitality. This single biomarker provides valuable insight into whether iron deficiency is causing your fatigue or if there are other iron-related concerns affecting your health.
What this means
Your transferrin levels are elevated above the optimal range, which typically indicates your body is working harder to transport available iron. This often happens when iron stores are low, and your body is trying to maximize iron absorption and delivery. It may explain symptoms like persistent fatigue or weakness.
Recommended actions
Increase iron-rich foods like lean red meat, poultry, beans, and dark leafy greens
Pair iron sources with vitamin C foods like citrus or bell peppers to boost absorption
Avoid tea and coffee with meals as they can block iron absorption
Consider retesting in 8-12 weeks along with iron studies for a complete picture
