1 Whole Blood EDTA 8 (6) mL   Refrigerated - 10 Day(s)/Room Temperature - 10 Day(s)  
ALTERNATE

Detects GAG deletion in the DYT1 gene in patient with Dystonia-1, torsion. Patients exhibit generalized or focal early-onset idiopathic torsion dystonia.

Physician Attestation of Informed Consent - This germline genetic
test requires physician attestation that patient consent has been
received.

Please label each specimen tube with two forms of patient
identification. These forms of identification must also appear on the
requisition form.

Higher blood volumes ensure adequate DNA quantity, which varies with
WBC, specimen condition, and need for confirmatory testing.

Patients, 0-3 years have higher WBC, yielding more DNA per mL of
blood
DNA yields and quality are better in fresh specimens. However, when
necessary, most genetic tests are successful from DNA purified from
whole blood that is several days old.

Other Acceptable specimen refers to Whole Blood "Pediatric
(0-3 years)"
Adult: 8 mL (6 mL) EDTA (lavender-top) whole blood
Pediatric: 2 mL (1 mL) EDTA (lavender-top) whole blood
