What is difference between Normal Range and Valid Range

What is difference between Normal Range and Valid Range , what the process to override the normal range values when try to override value of Hemoglobin test result value I am getting the following error(Result limit with the given validation already exists
) , I can understand from code perspective. I am not able to understand from functional perspective.

Thanks, that’s a great question.

Normal range is the clinical normal result for something. EG: Normal range 20-80 would mean anything within would be “normal” whereas 90 would be high.

Valid range means what we would expect a test value to possibly be for a sample from a human. so, for the above, maybe 20-80 is normal, and 5-199 is the valid range. So, if someone entered 255, it would prompt them that this is out of range and to check their entry. This helps in case of typos and other data entry errors.
