Which statement about the Chemistry section is true?

• A. It is the smallest section and least automated
• B. It is the most extensive and automated section
• C. It analyzes hormones and drugs
• D. It handles serology testing

Answer: (B)

The main idea is that the Chemistry section covers a broad range of chemical measurements and uses a high level of automation. In most clinical labs, chemistry runs a large menu of tests—electrolytes, glucose, lipids, enzymes, metabolites, kidney and liver function markers, and more—and relies on automated analyzers that process many samples quickly with minimal manual handling. This combination of extensive test offerings and heavy automation is what makes the Chemistry section the most extensive and automated part of the lab. Serology belongs to immunology, and while some hormone or drug tests can be run in chemistry, that field isn’t defined by breadth and automation in the same way. Hormones and drugs tests are often handled in specialized workflows, so the statement about being the most extensive and automated fits chemistry best.
