Most sample types not specifically tested during kit development can still work, but will require testing and optimization. Samples might need to be diluted or may have to be extracted to eliminate matrix interference. Optimal dilutions to get sample values to fall within the range of the standard curve will also have to be determined. In the end, if the analyte is still present in a concentration high enough that it falls within the range of the standard curve after the sample has been diluted sufficiently to eliminate matrix interference, or if the sample can be extracted and an acceptable amount of the analyte recovered, then the sample will work.
