A 72-year-old woman comes in with no pain at all — just a kidney filtration rate that slipped below 60 on routine bloodwork. No pathway to map, no symptom to chase. Here's how we approached kidney function with a Global Balance Shaoyin Taiyang pattern and Meridian Conversion III/VI — and why we're sharing the reasoning before the result.

Projection has limits. When the whole meridian is involved, when the function of an organ is off, when the Shen of a patient is affected — projection still works, but it takes a lot of needles and the result stays superficial. Meridian Conversion changes that.
