“一口唾液”可测孩子天赋 正规机构并无“天赋”检测

2017-08-30 14:16:30   中国青年网

不过,绝大多数家长认为,天赋基因检测没有实际意义,“纯属娱乐”。市民刘女士明确表示不会给孩子做类似的测试,“用这样的结果去干预孩子的兴趣,会扼杀了无数的可能性”。

B 价格:从几百元到上万元不等

价格方面,各家机构的检测收费标准不一。记者在淘宝上搜索发现,相关产品的价格从699元到69800元不等,有多种套餐可供选择。

为什么检测项目看起来差不多,价格却相差几倍甚至数十倍?某检测机构淘宝客服人员表示,基因检测的准确率取决于数据库的比对和分析,数据库越大,比对准确率越高。该客服人员声称,该公司拥有全基因组关联分析亚洲儿童基因数据库,所以价格不低,“数据库才是核心竞争力”。

记者采访了解到,目前基因测序方面,最先进的已经有生物纳米孔测序技术,但国内消费级基因检测公司针对普通用户一般采用基因芯片,这是接近于第二代的测序技术。测试人员把想要检测的基因位点放在一起设计成一个“套餐”,“套餐”种类很多,价格差别也很大。

“目前国内关于基因检测的定价并没有统一的标准。”英国国王学院医学院博士陈玲燕向记者分析称,目前基因检测机构很多,检测目标不一样,定出来的报价差别也很大。

她说,基因测序的成本分为测序和解读两块。测序价格取决于测序深度,要求的数据量越大,价格越高;解读价格包括生物信息分析和数据统计分析,这取决于解读人员的专业能力,“测序成本比较稳定,但是数据解读成本根据客户要求的不同,差异可以很大”。

“技术的发展降低了测序的成本。前期价格降不下来,一是设备等硬件的投入比较大,二来市场竞争没那么激烈。”WeGene联合创始人兼CTO陈钢对此直言不讳,继消费级基因检测公司“23魔方”日前将全套检测“祖源+遗传健康”999元的价格降到了499元后,WeGene也将原本999元的基因检测产品降至499元。

C 市场:正规机构并无“天赋”检测

羊城晚报记者了解到,目前市场上基因测序公司众多,但正规基因检测机构尤其是行业排名靠前的机构均无“天赋”检测的内容,而是集中在生殖生育、遗传病筛查、肿瘤检测等方面。

中银国际证券医药行业研究员邓周宇表示,目前市场上基因测序公司有很多,以二代测序为主的以华大基因、贝瑞和康、诺禾致源等为代表;传统测序技术为主的以厦门艾德、北京雅康博为代表;还有第三方检测公司,如广州金域检验、迪安诊断、达安基因等。
