Blood sample collection card is a new type of medium using plant fibers as the carrier for the storage of DNA, capable of combining DNA to the card, designed for the collection, transportation and storage of blood samples at room temperature. Through the unique formula and production process makes the product at the same time has the protein denaturation, cell membrane rupture, DNA adsorption and inhibition, the growth of bacteria, to ensure that the target DNA can be stored on the collection card for many years, and due to the protein denaturation makes biological samples of pathogenic microorganisms or virus loss, avoid the pollution risk of the operators, but also to ensure the safety of long-distance transportation. The blood sample collection card is divided into sample area, information area and label area. There are 4 sampling rings in the sample area, and each sampling ring can collect 75~80 μ l of whole blood.

 1. Convenient storage and cost saving: DNA samples can be transported and stored at room temperature for a long time, without refrigeration, greatly reducing the cost of DNA transportation and storage.
2. High DNA integrity: high quality DNA samples can be extracted using extraction kits.
3. High safety: inactivate the pathogenic microorganisms or viruses in the sample to avoid the contamination of the operators.
4. Multiple uses in one sample: one sample can be used for a variety of target DNA tests, and can be used for multiple times, for easy review and reexamination.

The DNA sample collection card has a wide range of applications, such as DNA collection, storage and transportation, medical identification and clinical diagnosis, etc. DNA collection, storage and transportation: DNA sample collection cards can be used for DNA extraction and PCR operation for forensic and paternity testing, and to establish a simple and easy to operate automated DNA extraction procedure by using automated DNA extraction instruments. Especially in the process of blood extraction for high-risk groups, the demand for the required blood samples can be greatly reduced, and at the same time, infectious bacteria or viruses can be inactivated to avoid the pollution of operators and strengthen the protection of blood collection personnel. In addition, DNA sample collection cards can also be used for crime scene DNA extraction and animal DNA samples collected in the field. Medical identification and clinical diagnosis: it can be used for the detection of some diseases caused by bacteria or viruses, and can also be used for genetic disease analysis and tumor detection. For the areas with poor medical conditions, if the patient's blood samples cannot be tested in time, the blood samples can be dropped on the blood sample collection card, and then transported or mailed to the unit with complete testing equipment for testing. For infectious biological samples, the process of storage on the blood sample collection card will lose its activity, so the safety is high.
