Collection Methods

We offer 3 specimen collection methods. A blood draw is the preferred method for genetic screening. We offer same-day courier pick up for all specimens.

Collection Methods

Give Your Patients Options

Blood

Whole blood collected in an anti-coagulant tube contains white and red blood cells. White blood cells contain a full set of genomic DNA with two copies of every gene. To isolate DNA from whole blood, white blood cells are broken open, all the proteins and lipids from the cells are washed away from the DNA, and the DNA is dissolved in water. Follow the link below for precise instructions about the collection and shipment of blood specimens.

Mouthwash

Both epithelial cells and white blood cells are present in saliva. By simply swishing mouthwash, cells in the saliva can be collected. Once the mouthwash arrives in the lab, the cells are broken open in order to isolate the DNA. Proteins and lipids from within the cells are washed away from the DNA, and the DNA is dissolved in water. Follow the link below for precise instructions about the collection and shipment of mouthwash specimens.

Buccal Brush

Cheek epithelial cells can easily be collected with the use of a few buccal brushes. By vigorously rubbing the inside of the cheek, cells collect on the brush. Once the brush tips arrive in the lab, the cells are washed off the brush and then broken open in order to isolate the DNA. Proteins and lipids from within the cell are washed away from the DNA, and the DNA is dissolved in water. Follow the link below for precise instructions about the collection and shipment of buccal brush specimens.

Support for Your Patients

While you work with your patients on deciding which screens match their unique circumstances, NxGen MDx handles all billing questions, specimen pick-up, and business operations. Your patients also have access to our board-certified genetic counselors who can walk them through their screening results and provide additional details on genetic diseases, risk factors, and the like. Counselors always encourage patients to rely on their healthcare providers as their best, first, and only source for making decisions regarding their medical health.
