DNA collection is the first step in most genetic research, but traditional blood collection methods are complicated to operate, costly, require cryopreservation of fresh blood, inconvenient to transport, and this method of blood collection causes injury and pain to many sampled individuals, which many people do not like.

Benefits of saliva collection: Saliva is rich in DNA and is a high quality source for sample collection. Saliva sample collection is a harmless and painless method of obtaining DNA. The method does not cause discomfort to the sampled person and is easily accepted, thus maximizing the sampling range for genetic studies and making it particularly suitable for molecular epidemiology large-scale population surveys. The DNA of saliva samples can be stored for years at room temperature, and is green and portable.

Edit

The saliva collector ensures that a clean and hygienic saliva sample is obtained and can be used for analysis. Saliva samples collected by this method do not need to be frozen.

What are the advantages of a saliva collector compared to a blood test?

The saliva collector will be simpler than a blood test: because there is no need to endure the pain of a blood draw, just a gentle spit of saliva and the sample is obtained.

saliva collectors will be more convenient than blood tests: the sample will be more stable than a blood test sample, the sample can be stored at room temperature for up to several years, and the sample can be easily transported

saliva collectors will be more efficient than blood tests: saliva collection facilitates automatic purification, and more and better quality DNA can be obtained

saliva collectors will be safer than blood tests: non-invasive sample collection reduces the chance of infection
