Theoretically possible. But under the current availabel technologies, one would have to have sensor (more likely multiple sensors) inside the body (roaming nanbots or implanted sensors at specific locations such as liver, kidney, heart etc). The sensors would collect specific data and have a micro-transmitter and the tricorder would receive and analyse the data captured.
