What is IGF-1 Z-Score?

The IGF-1 Z-Score compares an individual's IGF-1 level to the average IGF-1 level for their age and sex. A Z-score of 0 means the level is exactly average. A positive score is above average, and a negative score is below average. It standardizes the IGF-1 value, making it easier to interpret across different age groups.
