Is an IgE (Immunoglobulin E) level of 250 normal?

Patient's question:

Is an IgE (IgE) level of 250 normal? I am very worried. The child's symptoms keep recurring, and we have already had tests done. I hope the doctor can help us.

Doctor's answer:

For hepatitis B patients, if the globulin level exceeds 35.0 g/L, it indicates liver damage, which may lead to an imbalance in the albumin-globulin ratio and requires special attention. Timely treatment should be administered.
Immunoglobulin (Ig) refers to a globulin with antibody (Ab) activity or a chemical structure similar to antibody molecules. Immunoglobulins are a tetrapeptide chain structure composed of two identical light chains and two identical heavy chains connected by interchain disulfide bonds. Immunoglobulins are divided into five classes: immunoglobulin G (IgG), immunoglobulin A (IgA), immunoglobulin M (IgM), immunoglobulin D (IgD), and immunoglobulin E (IgE).
