Immunoglobulin G2 (IgG2) is a subclass of IgG antibodies that plays an essential role in the immune system by offering protection against bacterial infections, particularly those caused by polysaccharide-encapsulated bacteria such as pneumococci and meningococci.
Testing for IgG2 can be useful for identifying specific immunity problems, especially in cases where individuals frequently experience infections caused by polysaccharide-encapsulated bacteria. It also assists in the diagnosis of certain immunodeficiencies.
IgG2 levels offer insight into the body's response to specific types of bacterial infections. Abnormal levels may indicate an underlying problem with the immune system, specifically related to the defense against certain bacteria.
An increased level of IgG2 may indicate a recent or chronic exposure to specific bacterial pathogens. It may also suggest an overactive immune response against these specific infections.
A low level of IgG2 may indicate a reduced ability of the immune system to effectively respond to infections caused by polysaccharide-encapsulated bacteria. This can be a sign of a specific immunodeficiency, making individuals more susceptible to such infections.

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.
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.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.
