2. Triglycerides
3. Steroids
4. Lecithins

Question 2

1. HDL and LDL monitoring is much cheaper than measuring total cholesterol.
2. Total cholesterol measurements include cholesterol that will be destroyed as well as transported to tissues and stored.
3. HDL and LDL measurements are more general, and frequently are used in patients not at risk for heart disease.

Answer to Question 1

Correct Answer: 2
Rationale: Triglycerides account for 90 of the lipids in the body, and serve as an important energy source. There are three types of lipids important for humans: triglycerides, phospholipids, and steroids. Lecithins are a phospholipid.

Answer to Question 2

Correct Answer: 2
Rationale: Total cholesterol tests include the good and bad cholesterol, the good being the type that is destroyed and excreted while the bad is the type stored inside blood vessels. Total, LDL, and HDL tests are as accurate as the equipment and technicians that complete them. HDL and LDL are more specific tests, not more general. Gaining more specific information, not associated costs, is the primary reason for monitoring the HDL and LDL.
