Immunoglobulin, often shortened to Ig, is a type of protein produced by the immune system that helps protect the body from infection and disease. The amount of immunoglobulin in the body is determined by a variety of factors, including age, gender, and overall health. Generally, healthy adults have between 7-15 g/L of immunoglobulin in their serum, and this level can be used as a baseline for determining if Ig levels are abnormally low or high.
In cases where a person has a weakened or compromised immune system, physicians may recommend monitoring Ig levels to ensure they remain within a normal range. Low Ig levels can be an indication of chronic illness, infection, or certain autoimmune disorders, and high Ig levels can indicate an allergic reaction or an overactive immune system.
In general, it is important to maintain normal Ig levels in order to stay healthy and prevent infection and disease. If Ig levels are too low, your doctor may recommend a regimen of vitamin supplements, probiotics, or other treatments to help boost levels back to normal. If levels are too high, your doctor may recommend lifestyle changes such as avoiding certain foods or allergens, or taking immunosuppressant drugs to reduce Ig levels.
It is always best to consult with your doctor before making any changes to your Ig levels, as they can determine the most effective course of action for your individual situation.
