The combined GHRH + GHRP-6 stimulation test was the most reliable for evaluating GH secretory capacity, with high sensitivity and specificity for GH deficiency diagnosis — the recommended clinical test protocol.
Key findingCombined GHRH + GHRP-6 stimulation test demonstrated the highest sensitivity and specificity for GH deficiency evaluation compared to individual agent
What the researchers found
Combined GHRH + GHRP-6 stimulation test demonstrated the highest sensitivity and specificity for GH deficiency evaluation compared to individual agents, establishing it as the recommended clinical provocative test for GH secretory capacity assessment.
