a titer is a measurement of the amount (or concentration) of x that exists in y.<br><br>
What you're referencing are blood titers. This is where someone takes your blood and measures the amount of x that exist in your blood.<br><br>
People on this forum most often refer to this as getting their titers tested for a disease/illness.<br><br>
For example, if you've never been noticeably sick with the chickenpox but you don't want to vaccinate, you can get your titers tested to see if chickenpox antibodies exist. If they DO, you will show as being "immune" to chickenpox and it is unnecessary to get the vaccine.<br><br>
You can get your titers tested through your doctor.

<div style="font-style:italic;">Thankyou very much. So when abouts would you get this done? I'm guessing after the first DTaP and MMR shots?</div>
With the DTaP, the titre test doesn't really work (for the pertussis compnent, at least). They don't know what kind of response is "protective".<br>
For the MMR, you could test about 6 weeks after the first dose. If you're wanting to delay chickenpox but aren't sure at age 11 (for example) if your kid has already had it, you could test then. So when to test depends on what you're going for.
