Overview of the complement system
The defense against pathogens such as viruses and bacteria are mediated by the immune system which is in principle divided in two parts. The adaptive or acquired immune system is evolving throughout life and where one of the key elements is the development of specific antibodies.
The other part is the innate immune system which is already in place at birth. The innate system is a non-specific first line of defense comprised of cells and mechanism to defend against infection caused by other organisms. The complement system plays an important part of the innate immune system.
IBL-America offers functional complement testing assays for the Classical, Lectin (MBL), and Alternative pathways. A complement screen assay (includes each pathway) is also available.
