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.


 When you request deletion/duplication array testing as a reflex test after gene sequencing or as a single test, there are  changes to know about in the new year.  The charge for del/dup interpretation of a single gene remains the same ($952.00).  The cost of each added gene interpretation will remain at $112.00.  Now, however, if you choose to order additional genes (beyond 4), there will be no additional interpretation charge with a maximum del/dup analysis charge of $1288.00 per panel of genes.    We've also added 2 new CPT codes to improve insurance preauthorization of testing for certain vascular genes.  See DELETION/DUPLICATION ANALYSIS.

August 15, 2014

In our continuing effort to provide the most comprehensive clinical testing services available for inherited connective tissue disorders, the Collagen Diagnostic Lab is pleased to announce an expanded menu of available tests.  Beginning August 15th, genomic sequencing of new single genes (including MYLK, MYH11, PRKG1, FKBP14, PLS3 and CREB3L1), new panels (for Autosomal Dominant OI and Familial Aneurysms), and deletion/duplication studies by Array for all genes is available.  This includes deletion/duplication studies for FBN1 (Marfan Syndrome).  Please see our new Test Requisition Form (under 'Order a Test') for a list of all testing currently offered by the CDL.
