DNA sampling is a technique which enables the experts to find the purified form of DNA structure for testing. There are numerous approaches one can use to find the true sample. As a matter of fact, it is essential to consider the DNA sample accuracy in order to see the best outcomes. Those who have never done this before should try the details offered by the guidr. With the passage of time, we have updated the knowledge about sampling, testing and kit selection. Anyone willing to perform this test at home using the kit should not forget to see given points.

Swab the cheek:

This is a simplest approach to bring the DNA sample. This technique based on buccal swabs. Don’t be worried about the scratching. You are not required to hurt the inner cheek. All you have to do is scratch the inner portion gently for a few seconds (30 to 60 seconds). Multiple swabs may be required to get the DNA. There is no guarantee that a single swab would be enough to get the sample of DNA. It would be better to repeat the swabbing in order to ensure presence of DNA in the sample.

Hair strands are also useful:

This method is mostly used to ensure the presence of DNA in a sample. It is not painful as it sounds. All you have to do is pull a few hairs from your head. It would be great if you take 15 to 20 strands with follicle. Make sure that follicles are present with the hairs detached from the body. Remember the guidr tips when using this technique.

  • Don’t take hairs from the clothing or hairbrush.
  • Don’t cut the hairs with a scissor.
  • Never touch follicles as it may damage the sample.
  • Always use gentle approach to take hairs from the head.

Saliva sample technique:

This technique is common and effective. It is among the easiest ways introduced by the experts. Sponges are usually provided with the kits in order to collect more saliva for longer.

  • Don’t eat, drink, smoke or brush the teeth before using this method.
  • Avoid using mouthwashes.
  • Rinse your mouth with the help of warm water. This will clean the impurities properly.
  • Ask your baby to drink enough water for the same purpose.

Take necessary precautions:

We have tried to facilitate the users with necessary information in each method. Describing the sampling techniques becomes easier especially if precautions are also present. There is no need to take additional measures. DNA is a strong double helix which usually remains unhurt in different situations. However, it doesn’t mean that you will not consider the important precautions while taking the samples.

Store the sample carefully:

It would be better to use the kits for testing immediately after taking a sample. However, if it is necessary to store the sample then you should use proper measures.  Essential details about sample storage can be obtained with the guidr online.
