Serology is the study of blood serum (the clear fluid that separates when blood clots). Immunology and serology laboratories focus on the following: Identifying antibodies. These are proteins made by a type of white blood cell in response to a foreign substance. 6 Blood serum is a component of blood plasma. The two are closely related, so they’re often thought to be the same thing. Serum is a fluid found in plasma, and it contains many of the same solid components as blood plasma (such as electrolytes, antibodies, hormones, and other proteins). 7 plasma blod 8 Ett serum är en gulaktig transparent vätska som blir resultatet efter att man låtit blod koagulera och sedan avlägsnat blodkroppar och koagulationsproteiner. 9 Helblod = blod som inte befriats från någon beståndsdel, alltså finns cellerna kvar (röda- vita blodkroppar samt blodplättar). 10
