You mean the chemical test was done and came up as no leaking head gasket? If so, dandy. Everything else points to the coolant level just being low. If it is, you can add a small bottle of dye to the coolant, then search later with a black light. The dye will show up as a bright yellow stain that you can follow back to the source. Even though the chemical test came up negative, still check for the dye inside the tail pipe. That also indicates a leaking head gasket, even when no combustion gases are getting pushed into the cooling system.
