Collection Procedure for Human Peripheral Whole Blood Specimen:
When you submit an online request, you will receive a parcel by mail that will include the following items:
1. One Touch Activated Lancet
2. One EDTA (Lavender Top) microtainer tube
3. Documents that contain instructions for sample collection, customer information and genetic testing consent form
Please follow the simple outlined steps for sample collection:
Wash your hands with soap and water.
Identify the puncture site.
Twist off the tab on the lancet to break the seal.
Discard the tab.
Position the safety lancet firmly against the puncture site.
Press the lancet firmly against the puncture site. You should hear an audible click! Do not remove the device from the site until an audible click is heard.
The blade will safely retract once the lancet is removed from the puncture site. Discard the used lancet.
Open the microtainer tube. Apply pressure on the puncture area and fill the microtainer tube with blood. It is very important for the blood to flow into the microtainer tube. Do not scrape the puncture area against the side of the microtainer tube. This will affect the quality of the genomic DNA obtained.
Fill the microtainer tube with blood between the 250-500 microliters marks showing on the tube.
Close the lid firmly and invert the microtainer tube gently ten times to mix the blood with EDTA (Anticoagulant).
Label the tube with your name, date of birth and collection date. To obtain optimal results, the samples must be shipped the same day the blood specimen is collected. The pre-paid parcel is intended for overnight delivery at ambient temperature with arrival Monday-Friday during normal business hours. Alternatively, the blood can be refrigerated up to 3 days and shipped overnight at ambient temperature. Blood specimen that is shipped later will be tested and will only be processed if the genomic DNA quality and quantity permits. In hot weather a cool pack can be enclosed.
A blood sample will be rejected if: It is frozen or partially frozen. It is hemolyzed or clotted. Blood sample is collected from a patient who has undergone a heterologous bone marrow transplant.
Unless requesting the ctDNA genetic testing, we highly discourage the submission of samples from patients who have active hematological malignancies. If such patients are interested in the other panels offered at Ayass BioScience, LLC we recommend using genomic DNA sample extracted from a skin biopsy.
Nasopharyngeal swabs are used for the detection of respiratory pathogens such as RSV, influenza virus A & B or parainfluenza virus. A properly collected viral swab (one nare (a singlenostril) is sufficient) is necessary for detection of these organisms. After collection, specimens can be stored between between 2°C and 8°C for up to 5 days after collection in Universal Transport Media.
1) Tilt patient’s head back 70 degrees.
2) Insert swab into nostril. (swab should reach depth equal to distance from nostrils to outer opening of the ear.) Leave swab in place for several seconds to absorb secretions.
3) Slowly remove swab while rotating it. (swab both nostrils with same swab.)
4) Place tip of swab into sterile viral transport media tube and snap/cut off the applicator stick.
