Key result
Sub-normal basal levels of IGF-I and IGFBP-3 demonstrated a diagnostic sensitivity and specificity of approximately 70% for identifying growth hormone deficiency in children.
Why the study?
Do IGF-I and IGFBP-3 measurements accurately diagnose growth hormone deficiency in short children?
Observational (n=2,750)
Yes
Do IGF-I and IGFBP-3 measurements accurately diagnose growth hormone deficiency in short children?
IGF-I and IGFBP-3 testing is a practical and inexpensive initial diagnostic step for growth hormone deficiency in short children, though definitive proof requires GH measurements.
No takes yet. Share an insight, caveat, or question.
Supports IGF-I/IGFBP-3 testing as initial adjunct in short children; leaves open prospective validation before practice change.
Ranke et al. (2004) conducted an observational in Growth Hormone Deficiency (n=2,750). IGF-I and IGFBP-3 testing was evaluated on Diagnostic sensitivity and specificity. Sub-normal basal levels of IGF-I and IGFBP-3 demonstrated a diagnostic sensitivity and specificity of approximately 70% for identifying growth hormone deficiency in children.
