求翻译：一、在癌症早期CA19-9的浓度很低，这就需要传感器的检测限很小，二，有其他干扰的物质存在，所以检测CA19-9有一定的难度。是什么意思？ 待解决

In early cancer ca19-9 concentration is very low, which requires the detection limit of the sensor is very small, two other interfering substances, so the detection of ca19-9 there are some difficulties.

First, in an early cancer CA 19 - very low concentrations of 9, which would require the sensor detection is very small, 2, and there are other substances that interfere with the Test CA 19 - 9 there is a certain degree of difficulty.

First, is very low in cancer early time CA19-9 density, this needs the sensor the examination to limit very slightly, two, has other disturbance physical existence, therefore examines CA19-9 to have certain difficulty.
