Do you believe in a biomeridian test?

No! It's a complete scam. The device is a galvanometer (actually, the company registered it as a "Galvanic Skin response device” at the FDA), so basically, it measures the impedance (conductivity) of the skin. The rest of the processes are flashes and whistles. Be careful with the diagnostics you get with devices like this. The worst scenario is not that you end up being diagnosed with something you don’t have, but that you may have a real problem that won’t be diagnosed nor treated, due to fraud or ignorance of people who sell this service. The medical system may not be perfect (or even as ethical as it should) but they are enforced to follow a lot of procedures, testing, scientific validation, etc. The company who developed this product, just registered it as a skin impedance meter, proved it is safe, since it does not invade or affect the body and has clearance to sell it. Do the math. I actually met someone who bought this machine, and told me that the measure depends on how wet the hand or feet is (during the “diagnostic” your hand is sprayed with water constantly), and how hard you press the measuring tip.
