Diagnosis & Tests
A physical examination may confirm the presence of fractures, deformities, and other symptoms.
Bone X-rays may show multiple healed fractures.
The diagnosis is made by collagen studies done on a skin punch biopsy. Once the specific molecular diagnosis is known, family members can be tested by a DNA blood test. DNA testing on prenatal chorionic villus samples (CVS) can make the diagnosis during pregnancy.
Severe OI is visible on prenatal ultrasound as early as 16 weeks.
