Question: Did anyone develop the ability to have age and gender specific ranges for e.g. lab tests. I have found a few chats about the topic but no sure if work was ever carried out?
Am not sure if i understand this question. 
This is an example of normal ranges for Hemoglobin. Different lab tests and observations can have different normal ranges depending on the age and gender of the patient
Do you mean form validation of values depending on age and gender?
That is exactly what we are after. Is there a config option anywhere for age and gender validation
