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

Detects sequence variants in the GJB2 gene in patients with sensorineural non-syndromic hearing loss.

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.

Specimen Requirements:
8 mL (6 mL minimum) whole blood collected in two EDTA (lavender-top)
tubes
Pediatric (0-3 years): 2 mL (1 mL minimum)
Setup Schedule
Wednesday

Reported (Analytical Time)
16-23 days
