What is Varicella-Zoster IgA?
Varicella-Zoster IgA antibodies are specific proteins produced by the immune system in response to an infection with the varicella-zoster virus, the cause of chickenpox and shingles. These antibodies are a component of the immune system that helps protect against infections.
Why test for Varicella-Zoster IgA?
Testing for Varicella-Zoster IgA antibodies can be useful for determining whether someone has recently been infected with the varicella-zoster virus, or for assessing an individual's immune status against this virus. This is particularly important for pregnant women, immunocompromised patients, and prior to receiving a chickenpox or shingles vaccine.
What does it indicate?
The presence of Varicella-Zoster IgA antibodies in the blood indicates a recent or active infection with the varicella-zoster virus. This may assist in the diagnosis of unclear cases of chickenpox or shingles.
What does a high Varicella-Zoster IgA level mean?
A high level of Varicella-Zoster IgA antibodies may indicate recent exposure to the virus or an active infection with chickenpox or shingles.
What does a low Varicella-Zoster IgA level mean?
A low or non-detectable level of Varicella-Zoster IgA antibodies may mean that a person has not recently been exposed to the virus or that the immune system has not generated a strong reaction to the infection. This can also indicate that a person may be susceptible to infection with the varicella-zoster virus.
Frequently asked questions
Answers to what people usually want to know.
How does it work from order to result?
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
How quickly can I get tested?
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
Do I need to book an appointment?
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
