Using AD5933 to meassure 1-100Ohms on top of 30MOhms

So I am trying to do some bioimpedance measurements which are in the range of 1ohm -400ohms at frequency of 50hz to 50khz. I know that it can be used to measure that range of impedance though my issue is that the electrode we are going to be using is a micropipette with 1-30MOhms of resistance. I wasn't sure if there is some external circuitry I could add that would allow it to measure this.
