The Collagen Diagnostic Laboratory (CDL) is housed in the Department of Pathology at the University of Washington, Seattle, WA.  The CDL offers diagnostic testing for osteogenesis imperfecta (OI), several forms of Ehlers-Danlos syndrome (EDS), and select other connective tissue disorders.  We also provide consultation for clinicians and families with questions on these rare disorders, review x-rays and clinical history,  and offer research testing and enrollment in research studies.

WHAT'S NEW AT THE COLLAGEN LAB

At the Collagen Diagnostic Laboratory, we strive to provide comprehensive and accurate variant interpretations.  To adhere to professional standards, we have adopted the recently released ACMG/AMP guidelines for variant interpretation (Richards 2015).  Please review the CDL Policy for Variant Interpretation for more information.

Obtaining pre-authorization for genetic testing can be a confusing and frustrating process.  To help, under the Billing FAQ's section of this website you can find a template for insurance authorization ("Patient Insurance Verification Form"), a sample letter to verify insurance coverage  ("Insurance Verification of Coverage for Genetic Testing"), and a template letter of appeal if genetic testing is denied ("Appeal Letter of Medical Necessity after Denial of Genetic Testing").
