Can trace elements be tested in iron deficiency anemia?

Patients with iron deficiency anemia can undergo trace element testing. Trace elements include calcium, iron, zinc, selenium, and others. Elements such as calcium, phosphorus, and iron are helpful for improving memory, whereas phosphorus, chlorine, sulfur, and others may reduce immune function. Excessive lead intake accumulates in the body and cannot be excreted effectively, eventually leading to poisoning. Patients with iron deficiency anemia are advised to consume more foods rich in iron, such as fish, shrimp, and animal liver. Additionally, fruits rich in vitamin C, such as kiwi fruit and dragon fruit, are beneficial.
