Please find specimen requirement specifications above.

All submitted specimens must be sent at room temperature. DO NOT ship on ice.

Specimens must be packaged to prevent breakage and absorbent material must be included in the package to absorb liquids in the event that breakage occurs. Also, the package must be shipped in double watertight containers (e.g. a specimen pouch + the shipping company’s diagnostic envelope).

About

{slide=Test Description}

We offer targeted detection of a previously characterized variant(s) within the family. From a fresh EDTA blood sample, DNA is extracted directly and the target region is amplified and directly sequenced. To offer this testing service, the proband’s variant must be identified by our laboratory before testing relatives.
