DNA Testing

DNA testing refers to the deciphering of the genetic code carried by the human body through molecular biology and is mainly used to predict the probability of an individual suffering from a certain disease in the future, usually by taking a drop of blood, oral mucosa or other tissue cells from the person being tested.

In addition to regular medical checkups, cancer screening is also included in people’s daily medical checkup lists. If there is a tool or instrument that allows us to do the sampling at home, wouldn’t it be much more convenient? The buccal swab collection kit allows you to collect DNA at home.

Components of Buccal Swab Collection Kit

• Buccal swab (nylon flocked swab): 2pcs
• Sample preservation solution: 2pcs
• Barcode sticker: 4pcs
• Return bag: 1pc

How to use Buccal Swab Collection Kit

1. Check that the package of the buccal swab is undamaged and remove the buccal swab, taking care not to let the DNA buccal swab come into contact with other items to avoid contamination.

2. Wipe the buccal area of the mouth with a cheek swab about 20 times to ensure that enough oral mucosa is collected.

3. Place the nylon flocked swab tip in the sample preservation solution and break the swab handle at the break point.

4. Do it twice to get two tubes with DNA sample.

5. Put a barcode on the return bag.

6. Fill in the information.

7. Put the tubes in return bag and seal it.

8. Send DNA samples to the laboratory.

9. Get a lab report.

Blood collection is prone to pain and complex operation. Collecting human oral DNA is a safer way to collect DNA samples and therefore is widely accepted and very convenient for forensic identification.

Mouth Swab DNA Test Kit

Components:

Nylon flocked Swab: 2 pcs

Sample Preservation Solution: 2 pcs

Label Stickers: 4 pcs

Return Bag: 1 pc

Steps to Use the DNA Collection Kit

Step 1:

After confirming that the packaging of the nylon flocked swab is not broken, tear it from the seal and gently remove the mouth swab from the bag, taking care that the DNA swab tip should not touch objects other than the inner wall of the mouth (buccal) to avoid contamination.

Step 2:

Extend the buccal swab into one side of the oral cavity and scrape up and down the inner mucosa 5-10 times, keeping the force moderate enough to press against the inner mucosa of the oral cavity to ensure that the DNA swab tip is dipped into the oral mucosal exfoliated cells at all places. Then use a new mouth swab according to the same method on the other side of the oral cavity wall for sample collection.

Step 3:

Place the DNA swab stained with oral exfoliated cells into the sample preservation tube, break the swab stem and tighten the cap. Then shake the biopreservation solution up and down to mix the sample and preservation solution thoroughly.

Step 4:

Fill out the return shipping bag with complete information, place the barcode on the sampling tube cap where it meets the tube, and place them in.

Precautions

Please rinse your mouth with water before sampling to remove food residues from your mouth (please do not use mouthwash to rinse your mouth).

Do not eat, smoke, drink alcohol, etc., 30 minutes before sampling.
