Serology tests

Performed in Medical biology (clinical laboratory).

What is it?

A serology test is a blood test that looks for antibodies, the proteins the immune system makes against germs. It can show whether you have had an infection or been vaccinated.

What to expect

A blood draw from the arm takes under five minutes and may sting a little. No special preparation is usually needed.
