Dear Doctor, thank you for your inquiry. You can add up to 8 age entries by clicking the [Add Row] button at the bottom of the Reference tab. Please make sure to check the following two points: (1) You must enter both the average and standard deviation values for both male and female. If you only enter data for one gender, the reference will be incomplete. (2) The system compares the patient’s age with the closest lower reference age. For example, if you set a reference only for age 8, a patient who is 7 years old will show “no matching reference.” If you would like the reference to apply to all ages, please set the reference age to 0. This will ensure the reference is applied to every patient regardless of age. If you have any further questions, please feel free to contact us anytime. Thank you.

Thank you very much, that solves my question. But I have another one: Can I only modify the averages of the measurements I created? Doesn't it allow "Admin" measurements?
