What are the two general categories the Complement systems function falls into? -
Answer-Cell lysis by the MAC
Biologic effects of proteolytic fragments of complement
What are increased level of complement associated with? - Answer-Inflammatory
conditions
Trauma
Acute illness (myocardial infarction)
What are decreased levels of complement associated with? - Answer-Complement is
excessively activated
Complement is currently being consumed
Single complement component is absent
What is the use of C3b and C3d complement components? - Answer-For the
investigation of hemolytic transfusion reactions and autoimmune hemolytic anemias
Why is C-reactive protein prominent among acute-phase proteins? - Answer-Changes
show great sensitivity
, Independent of ESR and parallel to inflammatory process
erythrocyte sedimentation rate (ESR) - Answer-Non specific indicator of disease with
increased sedimentation of erythrocytes and is seen in acute and chronic inflammation
and malignancies
What are the majority of immunology tests done on? - Answer-Serum
What are the reasons for complement inactivation? - Answer-Complement interferes
with certain syphilis tests
Can agglutinate latex particles
Causes lysis of indicator cells
How is the inactivation of complement done? - Answer-Heating to 56 degree Celsius for
30 min
Latex agglutination - Answer-Antibody molecules bound to surface of latex beads
Flocculation tests - Answer-interaction of soluble antigen with antibody may result in the
formation of a precipitate (a concentration of fine particles)
- macroscopically and microscopically visible
What can Flocullation testing be used in? - Answer-Syphilis serologic testing such as:
Venereal Disease Research Laboratories (VDRL)
Rapid plasma reagin (RPR)
venereal disease research laboratory (VDRL) - Answer-Antibody like protein (reagin)
binds to antigen and produces flocculate

Immune System (IS) - Answer-Tissues, cells and biological mediators that work
together defending or protecting host organism from foreign substances and abnormal
cells
Immunity - Answer-Process by which a host organism protects itself from attacks by
external and internal agents
Acquired immunity - Answer-Formation of specific antigen-antibody and specific
responses
Self - Answer-Anything that is derived from the host
