What level of human chorionic gonadotropin (hCG) indicates pregnancy?

The level of human chorionic gonadotropin (HCG) is of significant importance in determining whether a woman is pregnant. Generally, when the HCG level exceeds a certain threshold, the woman can be considered to be in a pregnant state. However, the specific threshold may vary among hospitals due to differences in testing reagents and measurement methods. Under normal circumstances, an HCG level between 5-50 mIU/ml indicates a possible pregnancy, while an HCG level greater than 50 mIU/ml can be diagnosed as pregnancy. This standard is widely accepted in most hospitals and clinical practices. However, some hospitals might use different reference values—for example, some may set the cutoff at 0-5 IU/L or 0-10 mIU/ml. Therefore, when making a specific determination, it is necessary to refer to the reference values provided by the testing hospital.
