Abstract: The present invention relates to a system for predicting an incidence of disease from genetic polymorphism and uses the prediction result to form a personal nutrition complex. The system collects at least one personal information and single nucleotide polymorphism (SNP) information then exchanges the above information with databases including a personal database, a genetic risk database, an allelic frequency database, and a prevalence database. Finally, the system will output a prediction report and indicates a risk of specific disease and a plurality of abnormal genes. According to the prediction results, the system also can provide a plurality of nutritional supplement ingredients to form a personal nutrition complex. Users can receive a comprehensive and an effective nutritional supplement countermeasure about abnormal genes for prevention of the specific disease.

Abstract: A DNA collection kit comprises a foldable collection rod, a collection bottle, and a buffer comprising ethylenediamine tetraacetic acid (EDTA) at a concentration from 20 mM to 60 mM. A method for using a DNA kit comprises the following steps: collecting DNA from a collection portion of the foldable collection rod of the DNA collection kit; breaking the foldable collection rod from the groove of the rod body to obtain a DNA-comprising collection portion; and putting the DNA-comprising collection portion into the collection bottle comprising the buffer to prolong the preservation time of the DNA, wherein the buffer comprises ethylenediamine tetraacetic acid (EDTA) at a concentration from 20 mM to 60 mM.
