单凭一啐唾液便能获知多达114种基因特质,当中包括了过敏度、健康状况、疾病风险、营养需求、性格特质、皮肤状态、体能特质、和体重管理。 这项脱氧核糖核酸(DNA)检测能够测出我们体内的祖传基因和患上严重疾病的风险,但是此项检测到底有多准确可靠呢? 在这篇文章中将与大家分享DNA检测的一些讯息和知识,让大家对此项检测能有更多的认知并能够在做检测前有充分的准备。
1.唾液的DNA是从口腔内颊细胞和白血球细胞中所获取。
白血球能够提供高品质的DNA。研究显示唾液DNA中有74%是来自白血球,使到唾液也能够提供犹如从血液中所能够提取到的高品质DNA并用于这类的DNA检测。
2.唾液DNA绝大多数为人体DNA,并非源自于细菌。
同为以上所述,唾液DNA源自于人体的白血球,虽然唾液中也存有细菌DNA,但是对于此项检测并无大碍。此项检测所使用的2毫升唾液采样,能够提供足够的人体DNA,并大幅度减低细菌DNA的影响。2毫升唾液采样中有大约11%的细菌DNA,这比起漱口采样的66%和细胞刷采样的88%更为准确。
3.DNA检测并不能取代常年健康检查。
DNA检测能够得知我们是否是带因者(即您可能不会有疾病,但可能因为基因关系而影响下一代患上疾病的风险)。 拥有了这些讯息,能够让我们提早准备与预防, 但需切记此项检测并不能取代常年的健康检查。
