Part 2 – IgG Deficiency FAQs

In part one of this series, we answered the questions:

  • What is an IgG deficiency?
  • What causes an IgG deficiency?
  • What are the symptoms of an IgG deficiency?
  • What treatment options are available?
  • How is it diagnosed?

Let us shed more light on this condition:

What are normal IgG levels?

Age and sex must be considered to determine a normal IgG level. Typically, an IgG level between 6.0 g/L and 16.0 g/L is considered normal. If your levels are less than 6.0 g/L or higher than 16.0 g/L, this is a sign that your body is not producing enough or producing too much immunoglobulin G antibodies. Both issues can cause infections. (Note – g/L stands for grams per liter.)

When should I visit a doctor for an IgG deficiency?

If you deal with recurring infections and your healthcare provider has not diagnosed the root of the problem, make an appointment with us so we can check your immunoglobulin G levels. A below average or higher than average level of IgG may be the culprit of your recurring infections.

If you’re already on a treatment plan and feel the first signs of an infection, call your doctor right away. The sooner you can receive treatment for the infection, the less severe and long-lasting it may be.

Can an IgG deficiency occur in children?

Yes, it can occur in people of all ages. Early diagnosis is key to have an effective treatment plan and less severe infections. However, no matter your age, it’s never too late to start on a treatment plan – such as medicine or IV therapy — like:

  • HYQVIA
  • Hizentra
  • Cutaquig
  • Intravenous Immunoglobulin (IVIG)
  • Subcutaneous Immunoglobulin (SCIG)
