The following may be of use to convince or show docs how this test is done, that it is possible.
Below, there are numerous examples of how they did genital fibroblast cultures to check for syndromes of androgen insensitivity/resistance, and 5AR2 deficiency. One can also measure 5AR2 activity via certain ratios in the 24-urine panel, as noted in one of the docs below.
If you print this stuff out, highlight relevant passages etc, you should be able to provide enough info to show it is possible. These tests CAN be done, but often are done in research labs so not sure if possible to do commercially… if not, maybe doc can partner with a researcher in androgen metabolism, AIS or professor of andrology/andrologist at a University that has such a lab and could do the investigation.
Examples of genital skin fibroblast cultures and testing mentioned in following papers:

pg. 2 lists how they did genital fibroblast culture, under “METHODS”.
