What Does This Test Measure?

IgG antibodies are a type of immune protein your body makes after recovering from chickenpox or shingles. They remain in your system for years, providing long-term protection. This test detects these antibodies to confirm past infection or immunity.

Why Might You Need This Test?

Your doctor may order this test if you have a history of chickenpox, shingles, or if you’re planning to be around someone with chickenpox or shingles to ensure you’re immune. It can also help diagnose or monitor conditions like shingles or confirm exposure in certain situations.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your arm or hand to draw blood. The process takes just a few minutes, and you can resume normal activities afterward.

What Are the Possible Results?

Results are qualitative (positive/negative) and indicate whether you have detectable IgG antibodies. A positive result suggests past exposure or immunity, while a negative result means you likely haven’t been exposed recently.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Short name
