Specimen Requirements

Submit only 1 of the following specimens:
 

Blood
Container/Tube: Lavender-top (EDTA) tube

Specimen Volume: 10 mL whole blood for adults, 7mL whole blood for pediatric

Collection Instructions: Invert several times to mix blood. Send specimen at ambient temperature in original VACUTAINER.

Dried Blood Spot

Obtain specimen using a Genzyme Genetics provided filter paper card (minimum volume: 3 completely filled circles) as follows:
1. Sterilize, allow skin to dry, and puncture finger with sterile lancet.

2. Allow large blood droplet to form.

3. Touch filter paper to blood and allow to soak through completely in each circle. Total saturation of circles must be evident when paper is viewed on both sides. Do not apply blood to both sides.

4. Use of capillary tubes is not recommended because they tend to roughen filter paper and cause over absorption.

5. Allow blood spots to air dry thoroughly for 2 to 3 hours at ambient temperature. Keep away from direct sunlight and heat. Do not stack filter papers before they are thoroughly dried. A protective cover may be used to hold specimen while drying.

6. Cover with end flap only after specimen is completely dry.

7. Maintain sterility and forward promptly.

Note: The following are unacceptable specimens:

1. All circles are not completely filled

2. Blood is layered by application on both sides or by multiple spotting

3. Filter paper is scuffed or torn

4. Specimen is contaminated or improperly dried

5. Incomplete information
