What is Cyclosporine Blood Test? (Background Information)
- Cyclosporine is an immunosuppressant drug. The brand names for cyclosporine include Sandimmune®, Gengraf®, and Neoral®
- Cyclosporine is used to prevent organ transplant rejection, most notably of the kidney, heart, and liver. It is also used to treat autoimmune diseases, such as rheumatoid arthritis and Crohn’s disease
- Cyclosporine works by preventing T-lymphocytes, a type of specialized white blood cell, from producing interleukin-2 (IL-2). IL-2 causes the growth and division of T-lymphocytes. Thus, by preventing its production, cyclosporine suppresses the immune system
- The immune system is responsible for defending the body against foreign invaders. These include bacteria, viruses, and other microorganisms
- Immune system suppression may be desired after purposely introducing a foreign object into the body for a therapeutic purpose. An example of this is an organ transplant
- Excessive or inappropriate T-lymphocyte stimulation is also responsible for a variety of diseases. Cyclosporine is sometimes used to suppress the immune system and diminish the harmful effects of abnormal T-lymphocyte stimulation
- However, like every other drug, cyclosporine must be kept within a certain range to prevent unwanted effects. If levels are too high, toxicity may result; if levels are too low, the drug may not be of a therapeutic value
- A Cyclosporine Blood Test is a test to assess the levels of cyclosporine in blood. It is used when adjusting the initial dose, and to ensure that cyclosporine levels stay within an acceptable range
