SAMPLE REQUIREMENTS

Fresh peripheral whole blood is our preferred specimen type. We also accept saliva as well as DNA. We offer kits for either blood or saliva specimen collection; please contact us at info@neurocode.com to request a kit.

WHOLE BLOOD (PREFERRED)

Blood should be collected in an EDTA (lavender top) vacutainer tube and spun lightly to avoid partial clotting.

Volume:

3-5mL of peripheral blood. For pediatric patients (less than 1 year of age), we can accept 1-2ml (minimum) if necessary.

Storage and shipping:

The collected sample can be stored at room temperature and should be shipped the same day as the blood draw. If same day shipping is not possible, the blood sample can be stored at 4°C (for no longer than 3-4 days) or at -20°C for longer periods. Stability may be affected if stored at room temperature for more than 3 days. Please contact us at info@neurocode.com if your sample is more than 7 days old. Samples can be shipped at room temperature by 2-day delivery with the arrival of Monday-Friday. During hot weather, we recommend shipping samples overnight with an ice pack.

Special notes:

Blood samples from patients who have ever received a heterologous bone marrow transplant are not accepted. Transfusion patients are required to wait at least 2 weeks after a packed cell/platelet transfusion, and at least 4 weeks after a whole blood transfusion prior to specimen collection.

SALIVA

Saliva samples should be collected using an Oragene kit, or a Neurocode Rinse kit. Collect the sample into the tube provided according to the instructions included with the kit. Please contact us at orders@neurocode.com for a saliva collection kit for patients that cannot provide a blood sample.

Storage and shipping:

The collected sample can be stored at room temperature and is stable up to 1 year (do not refrigerate or freeze saliva sample). We recommend sending the specimen soon after collection. Samples can be shipped at room temperature by regular mail (special shipping e.g. overnight is not required).

DNA

Isolated genomic DNA samples can be sent in any sterile plastic tube. Information regarding:

  1. the method used for extraction

  2. the collection date

  3. the source of the DNA (e.g. tissue or sample type)

   

must be included with the sample.

Amount:

At least 2ug of DNA in TE Buffer. DNA must be at a minimum concentration of 50 ng/ul and DNA OD 260/280 ratio between 1.7-1.9). Please send agarose picture with high molecular weight genomic DNA, if available. We recommend using a fluorescence-based approach for quantifying the DNA specimen. If you choose to quantify DNA by absorbance, we require twice the amount of DNA (at least 4 ug) due to likely overestimation of the true amount. We perform an initial quality control step on all DNA specimens received. DNA specimens that fail this QC will be returned or safely disposed of at no charge.

Storage and shipping:

DNA sample should be stored at 4°C until ready for transport. If long term storage is required, DNA should be frozen at -20°C. Samples can be shipped at room temperature by 2-day delivery with the arrival of Monday-Friday. We recommend including ice packs in hot weather or if shipping is expected to take longer than 48 hours.

Special notes:

We do not accept DNA samples extracted from paraffin-embedded tissue.​​

We accept packages on regular work days, Monday through Friday. Please do not request Saturday delivery. For international shipping, a commercial (ProForma) invoice is required on the outside package along with the waybill. A sample invoice for DNA is available. Please be sure to also include a customs declaration form. 

Blood, DNA and saliva samples can be shipped at room temperature. For blood and DNA samples, express delivery is recommended. Blood samples collected on a Friday or over the weekend should be kept at 4°C and shipped on the next business day with overnight delivery. Keeping the specimen refrigerated over the weekend will not compromise sample quality.

Package the specimen(s) according to approved transportation policies. Include the completed test requisition form in the shipping container. Ensure name and identifying number on the specimen match those on the test requisition form and clearly indicate the test being ordered. Incomplete forms will result in either delay of testing, or sample rejection. Incorrectly stored or transported samples will result in sample rejection
