The wti gene should be the WT1 gene. positive WT1 gene indicates that the patient has not reached the level of molecular remission, and further refinement of flow cytology, chromosome and other tests are needed, and then treatment will be based on the test results. In addition, the value of each laboratory test may vary, and it is necessary to make a comprehensive judgment based on the trend. WT1 gene is a transcriptional regulator with dual roles in the human body, which has an important role in the proliferation, differentiation, apoptosis and other processes of human hematopoietic cells. Clinically, the examination of WT1 gene can clarify the situation of patients at different periods, so as to understand the condition, treatment and recovery of patients. WT1 gene test has a very important role in the treatment of the disease and after treatment. Under normal circumstances WT1 gene is negative. If there is a positive test result, it means that there may be leukemia or the condition of leukemia patient has not been effectively cured or there is a relapse and so on. When the WT1 gene is positive, it is recommended to consult a doctor in a timely manner and actively treat the disease under the guidance of a physician to avoid aggravation of the condition.
