What other molecules are monitored along with hdl and ldl

Triglycerides.

Explanation:

Triglycerides are a type of fat found in the bloodstream, and is used to store energy and give energy to the muscles - High levels increase the risk of heart disease, saturated fat.

There is a blood test that measures your triglycerides, along with your cholesterol. Triglyceride levels are measured in milligrams per deciliter (mg/dL). The guidelines for triglyceride levels are levels above 150mg/dl may raise your risk for heart disease. A triglyceride level of 150 mg/dL or higher is also a risk factor for metabolic syndrome.

A high triglyceride level combined with high LDL (bad) cholesterol or low HDL (good) cholesterol is linked with fatty buildups within the artery walls, which increases the risk of heart attack and stroke.

The molecules that are monitored along with HDL and LDL are: triglycerides.

Explanation:

HDL, LDL and triglycerides are all lipids (fats) of great clinical importance since they can indicate certain diseases in patients.

HDL (also called "good cholesterol") is a high density lipoprotein cholesterol. HDL carries cholesterol away from the organs and back to the liver, this can be very beneficial to one's health.

LDL (called "bad cholesterol") is a low density lipoprotein cholesterol. LDL works exactly the opposite of HDL: it carries cholesterol and deposits it in arteries, which can lead to atherosclerosis (a serious disease caused by big amounts of cholesterol occluding the arteries that can cause strokes and heart attacks).

Triglycerides are fats used to store energy, but higher than the desired amount can increase the risk of heart disease.
