Final answer:
Blood tests for cholesterol, troponin, and HDL are chemistry-related analyses processed in the Chemistry department.
Step-by-step explanation:
The tests for cholesterol, troponin, and HDL are processed in the Chemistry department of a clinical laboratory. These tests are part of a lipid panel and are biochemical analyses focusing on substances found in the blood's plasma. The chemistry laboratory carries out tests to determine various metabolites within the plasma, including lipid levels such as cholesterol and HDL, as well as proteins like troponin.
