There are not a lot of precautions to take when having your blood drawn for the Cyclosporine concentration test, just the time you take the Cyclosporine and the time you have your blood drawn, and the fact that you have to go to the blood draw on an empty stomach. Before you have your blood drawn for the cyclosporine concentration test, you need to take cyclosporine the night before at about 8:00 p.m., and keep an empty stomach when you have your blood drawn the next day. If, after the test, the trough concentration of cyclosporine is 150-200 ng/ml, this is normal. If, after the test, the result is found to be high, it may be due to side effects, possibly related to your own reasons. When taking cyclosporine, it is important to choose the appropriate method of administration and to test the concentration of cyclosporine regularly. Cyclosporin concentration test when drawing blood is not very different from ordinary blood drawing, when there is an abnormal test, it is necessary to carry out another examination in time. If the corresponding disease is detected, the treatment should be actively carried out, and actively cooperate under the guidance of the doctor.
