IG
The IG test measures immunoglobulins, which are proteins produced by your immune system to help fight infections. Clinicians typically order this test to assess immune function, diagnose immunodeficiency disorders, or monitor certain diseases such as multiple myeloma or chronic inflammatory conditions. The IG test is commonly used in clinical situations where a patient's immune response is in question, helping healthcare providers understand how well the immune system is functioning and if any abnormalities are present.

Clinical Information
Clinical Significance
Abnormal results from the IG test may indicate various conditions. High levels of immunoglobulins can suggest chronic infections, autoimmune disorders, or certain types of cancer. Low levels may point to immunodeficiency, making patients more susceptible to infections. It's crucial to remember that only a licensed healthcare provider can accurately interpret the results of the IG test in relation to your overall health.
Reference Ranges
Reference ranges for immunoglobulin levels can vary based on factors like age, sex, and the specific laboratory methods used. Generally, these ranges are established from healthy individuals and are used to interpret test results. It's important to consult with your healthcare provider to understand what the specific reference ranges mean in your context.
Sample Preparation
Before your IG test, no special preparation is generally required. However, it's a good idea to inform your healthcare provider of any medications or supplements you are taking, as they may suggest adjustments if necessary. Typically, fasting is not needed for this test, so you can eat and drink normally unless otherwise instructed by your provider.
