Normal Values:

Pathological Values:

>400 mg/dL (may indicate iron deficiency)
< 200 mg/dL (may indicate iron overload or chronic illness)

Low transferrin levels can indicate chronic illness, malnutrition, or iron overload, leading to symptoms such as fatigue, joint pain, and liver issues.

Symptoms/Pathology in Deficiency:

High transferrin levels often point to iron deficiency anemia, resulting in symptoms like fatigue, weakness, and pale skin.

Symptoms/Pathology in Increase:
