Theoretically it is possible to measure the micronutrients with iCheck in rice kernel. However no validation study has been done and no sample preparation protocol is available. A Proof-of-concept study can be initiated on request from customer. A POC has been performed with extruded rice fortified with ferric pyrophosphate. iCheck Iron test kit cannot be used to measure extruded rice with available sample preparation protocol.
