A client seeks a simple, small, and cost-effective diagnostic cholesterol test kit. The technology must be used directly by a consumer, possibly as an in-home test kit. Results should be visible immediately and show different levels, including normal, moderately elevated, or high cholesterol. Solutions could be minimally or non-invasive diagnostics that detect one or multiple states, and could include tests for blood, breath, saliva, sweat, urine, or tongue scraping. Ideally, tests must be validated against standard blood cholesterol tests, and detect a 10% change in total cholesterol.
