DNA Diagnostic Sample Requirements and Shipping Information

1. Draw 2 lavender top (EDTA anticoagulant) tubes of blood (7-10 cc) from each adult. For children, draw 1 lavender top tube of blood. Label the tubes with the patient's full name and date of birth. Maintain the sample at room temperature. Sample stability is approximately 5-7 days. We will also accept high quality extracted DNA (not less than 25 micrograms).

2. Pack the tubes in a sealed plastic bag and place in a container with sufficient material to absorb the entire volume of blood if the tubes should break to prevent the possible spread of blood-borne pathogens. Send the sealed container by overnight express with priority delivery. DO NOT USE EXPRESS MAIL THROUGH THE POST OFFICE. Send samples to arrive Monday through Friday. Do NOT mail on Friday, as the laboratory is closed weekends. Be alert for Monday public holidays and avoid delivery on long-weekends. If a sample is collected on Friday, do not mark for Saturday delivery. Federal Express will normally deliver the sample on the following Monday.

3. Include the requisition along with the sample. Please fill in these forms as completely as possible. We must have the name and birth date of the patient, the name, address, and phone number of the referring physician, the test ordered, ICD-9 diagnosis, and the indication for the testing.

4. For predictive DNA testing (e.g. presymptomatic Huntington's Disease) an informed consent is required.
