What This Test Measures

The test combines imaging (likely a CT scan or similar) to analyze bone density, bone growth patterns, and structural integrity of your skull. Additional blood tests may measure specific markers related to bone metabolism or growth factors to support the evaluation.

Why It’s Done

This evaluation may be recommended if you have a history of craniofacial abnormalities, developmental delays, or if you’re being monitored for conditions like craniosynostosis (premature fusion of skull bones) or other skeletal disorders.

Common Conditions Evaluated

The test helps diagnose structural issues such as abnormal skull growth, bone density irregularities, or conditions affecting facial development. It may also assess the effectiveness of treatments for existing craniofacial conditions.

Sample Collection and Preparation

For imaging: No special preparation is needed, but you may be asked to fast or avoid certain medications. For blood tests: A blood sample is drawn from a vein, typically in the arm. You may be asked to fast for 8–12 hours before blood collection if instructed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long will the results take to return?
Results from imaging studies are usually available within days to a few weeks, depending on the facility. Blood test results may take a few days to a week to process and interpret.
Can I get my results over the phone?
Yes, your healthcare provider or lab will contact you to discuss results. You may receive a call or have a follow-up appointment to review findings with a specialist.
What if my results are abnormal?
If abnormalities are detected, your doctor will explain next steps, which may include further imaging, additional tests, or a referral to a specialist like an orthodontist or craniofacial surgeon for treatment planning.
