“For diagnosis of tumor, you will need a conventional tissue biopsy. If your liquid biopsy is negative for certain mutations, you may need to have follow-up testing done on a conventional biopsy specimen. A liquid biopsy may miss details available from a conventional tissue biopsy and can't determine where in one's body a mutation has arisen.
In some situations, a liquid biopsy alone can provide sufficient information for making treatment decisions. It may be sufficient if, for example, the primary test is positive for a mutation or if a T790M mutation is detected and a tissue biopsy cannot be obtained. While liquid biopsies are promising and powerful tools, they complement but do not necessarily replace tissue biopsies for the foreseeable future."
没有关系,而是医生的关系。我有问了一下国内其他的人,他们说现在的这种测试公司很多,公司的代表就像过去的医药代表在门口等着,医生用自己的关系。所以,我的朋友不敢让这个公司测,因为,下次肯定还要看其他医生,万一那个医生一看报告不是他自己的关系户出的生气了就不好办了。费用一共两万,全自费。
有一点是我有一亲戚,公司做出阳性,但医保要求三甲医院的结果证明,结果三甲医院又针对性的做了一次,结果阴性。再一看,公司报的阳性结果不可靠 (<1%的阳性率)。但公司做的比较全面。最后看病人是由那个医生治,和医保要求谁出报告来决定到哪里检测。这样比较好。
要的钱比较贵,而且保险应该付。我有些怀疑医生有没有能力好好利用这些测试结果。
结果意味着什么,或请他们给出参考文献和资料。一般美国公司愿意回答这样的问题。
以前类似检测基本都是免费的,现在估计公司风投减少,压力很大。不过,两万人民币不算贵,如果需要靶向治疗也只能认了。不同公司检测包含的基因量不一样,数据处理程序也不同,有时无法比较不同检测的结果。

临床用什么最说明问题。
请你问问你的同伙有谁在做这个
这是做科研的基本素质,做医生也如此。
我猜测是医生参加了某项有关研究,医院也在收集这些信息,都是潜在的商业利益
从技术上来说,液态活检没有问题,但是有了活检组织还要血液干什么?只能是为了实验
原帖最初没有说组织活检,只说抽血基因检测,才给了那个解释,结果......
