Is there a test for brittle bone disease?

Severe cases evident: The more severe cases are evident before birth by ultrasound & or neonatal x-rays.Classification of lesser forms are based on age of first symptoms or specialized testing. My last case involved a skin biopsy and analysis of enzyme production in a specialty lab. Have your dr locate a genetics department at a med school or children's hospital if you want to pursue this testing. They can set it up.

Brittle bone: Its called a DEXA scan.
