IGF-1 Calculator

The IGF1 Z-Score Calculator can be used to calculate a patient’s standard deviation score (as a Z-Score) based on IGF-1 patient results provided. The calculator uses the provided information, and calculates the Z-score based on the patients age, gender, IGF-1 result, and the appropriate reference interval. Calculated Z-Scores are listed by tanner stage, which can assist with identifying the most appropriate Z-Score for patients if they are within the specific tanner stage. Please note this information is only valid for patient results provided by Labcorp.

To use the IGF1 Z-Score Calculator, please enter the patient’s birthdate, gender, and IGF-1 patient result. After selecting “calculate”, the appropriate Z-Score by tanner stage will appear.
