Q: "What options does it include?"

Just educated ;)

About 30 years ago, my family discovered we had the genetic mutation that could yield porphyria. At the time, the only solid test for people not expressing obvious symptoms like my sister was looking for the presence of excess porphyrins in the urine.

I thought Ariel contacted someone else who had done it before for their Hayabusa V8... I forget if it was a British or German firm.
