Description:
Immunoglobulin D IgD Blood Test
This test measures the level of Immunoglobulin D (IgD) in the blood. Immunoglobulin D is a type of antibody produced by the body's immune system. Normally, IgD levels are very low and not detectable by standard blood testing. The primary condition associated with elevated Immunoglobulin D is Hyperimmunoglobulinemia D syndrome (HIDS). HIDS is a genetic disorder that can affect the nervous system. Common symptoms of HIDS include recurrent fevers which last 3-7 days, skin rash, swollen lymph nodes, joint pain, abdominal pain, vomiting, and diarrhea. Most people with HIDS will display elevated levels of Immunoglobulin D so testing can aid in making a diagnosis.
A small number of people with Multiple Myeloma, a form of blood cancer, will show detectable IgD levels. In these cases, measuring IgD can help to confirm a diagnosis or differentiate multiple myeloma from other disorders. However, most people will not show high levels of Immunoglobulin D even with Multiple Myeloma so it is not an effective method for screening.
Immunoglobulin D is typically ordered to aid in diagnosing conditions associated with elevated IgD levels, especially if someone is experiencing symptoms.
Turnaround for this test is typically 3-6 business days.
