According to Dr. Silverman, children who exhibit signs of early puberty should be referred to a pediatric endocrinologist who will conduct a thorough review of a child's medical history and a physical examination. Further evaluation may include a series of lab tests and imaging tests to determine if a child has CPP and if there is an underlying cause for the condition.

Tests may include the following:

• Hand/wrist x-ray: To determine whether the bones are maturing early and the rate of progression.
• Blood tests: To check the levels of various hormones.
• GnRH stimulation test: To determine whether sex hormones in the child's body are at levels seen during puberty.
• Pelvic and adrenal ultrasound: To determine whether the ovaries, testicles or adrenals are normal.
• Magnetic resonance imaging (MRI) or computer assisted tomography (CAT) scan of the head: To determine whether the parts of the brain that produce hormones are all normal.
