Will we still be able to enter "UTR" if we are unable to read certain vital signs for a patient?

Users will no longer be able to add alpha characters within the height, weight and blood pressure field. According the Stage 2 specification sheet for Recording Vital Signs, the only information required to be inputted by the provider is the height and weight, and/or blood pressure of the patient. The certified EHR technology will calculate the BMI and growth chart is applicable to a patient based on age.
