Triglycerides (TG) in Serum analysis is a laboratory test used to measure the levels of triglycerides in the blood, which are a type of fat produced by the body from carbohydrates and dietary fats. Triglycerides are a major source of energy, but elevated levels may indicate health problems. High triglyceride levels are considered a risk factor for cardiovascular diseases and can also signal other issues such as metabolic syndrome and diabetes. This test is recommended as part of routine screening for adults, especially those with risk factors such as obesity, high blood pressure, or a family history of heart disease. The test is performed by drawing a blood sample from a vein, preferably after fasting for 9-12 hours to ensure accurate results. The results are interpreted by a doctor in the context of the patient’s overall health and may require follow-up or lifestyle changes if the levels are high.
