Blood test may help solve early puberty puzzle in girls

NCT ID NCT07359092

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at 143 girls to see if two natural chemicals in the blood, spexin and phoenixin-20, can help doctors tell the difference between true central precocious puberty and a harmless condition called premature thelarche. Researchers measured these chemicals in girls with early breast development and in healthy controls. The goal is to find a simple blood test that could guide diagnosis and avoid unnecessary treatments.
