Lab values

• 1\. The following laboratory or auxiliary examination abnormalities are present during the screening period:
• Any abnormal laboratory examination with clinical significance. For laboratory examinations with clinical significance, if there is a clear and reasonable reason, retesting can be performed within one week and the retest results used to determine whether the subject meets the criteria;
