两个意义不一样啊，定性是确定你抗体是阴还是阳的，如果阳证明2个情况，一个是你感染了丙肝病毒，另一个是你曾经感染过这个病毒，现在已经好了。但是到底是哪个情况还要进一步做定量测试既病毒RNA检测。如果这个测试值在最低线以下就证明你现在没事，不具有传染性也不是患者只是携带者；如果高于最低线那你就是患者了，就需要治疗
如果要是直接注射，就不知道了
1.步骤简单，45分钟内完成测定，比经典Lowry法快4倍而且更加方便。
2.灵敏度高，检测浓度下限达到25μg/ml，最小检测蛋白量达到0.5μg，待测样品体积为1-20μl 。
3.BCA法测定蛋白浓度不受绝大部分样品中的去污剂等化学物质的影响，可以兼容样品中高达5%的SDS，5%的Triton X-100，5%的Tween 20，60，80。
4.在20-2000μg/ml浓度范围内有良好的线性关系。
5.检测不同蛋白质分子的变异系数远小于考马斯亮蓝法蛋白定量。
加入荧光标记探针，巧妙地把核算扩增、杂交、光谱分析和实时检测技术结合在一起，借助于荧光信号来检测PCR产物。一方面提高了灵敏度，另一方面还可以做到PCR每循环一次就收集一个数据，建立实时扩增曲线，准确地确定CT值，从而根据CT值确定起始DNA的拷贝数，做到真正意义上的DNA定量。另外由于CT值是一个完全客观的参数，CT值越小，模版DNA的起始拷贝数越小。因此，利用CT值确定DNA拷贝数实时PCR方法比普通终点定量方法更加准确
MicroBCA试剂测定范围是0.5-20μg/ml
