Blood test is a means of testing health. Through the detection of blood, we can know the indications of various components in blood, which is convenient for judging the health status of the body. The blood test only takes a very small amount of blood in the body, which is harmless to the body. Therefore, parents should support an open attitude towards blood tests.
At present, there are more scientific and accurate detection methods than blood test, such as gene decoding, which is a technology to understand people's health from the genetic level. Related to this, gene decoding technology does not need to harm the body or draw blood. Gene decoding technology only needs to scrape a small amount of oral mucosal cells from the mouth to complete the detection.
