Study Notes

Triglyceride Testing

Triglyceride testing is a vital part of lipid profiles, used to assess cardiovascular risk and metabolic health.
Normal triglyceride levels are below 150 mg/dL.
Borderline high levels are 150-199 mg/dL.
High levels are 200-499 mg/dL.
Very high levels are 500 mg/dL or greater.
Fasting for 9-12 hours before testing is crucial for accurate triglyceride measurements as levels fluctuate after meals.
Blood samples are typically drawn from a vein in the arm using standard venipuncture.
Elevated triglycerides link to higher cardiovascular disease risk (heart attack, stroke), and may signal metabolic disorders like diabetes and pancreatitis.

Clinical Significance of Triglycerides

High triglycerides might indicate obesity, excessive alcohol use, uncontrolled diabetes, hypothyroidism, or liver disease.
Certain medications (like thiazides and beta-blockers) can also elevate triglycerides.
Levels above 500 mg/dL require immediate medical intervention to prevent complications like pancreatitis.
Lifestyle changes (diet and exercise) and potentially medications are often recommended for managing high triglycerides.

Cholesterol Testing

Cholesterol testing is essential for assessing cardiovascular health and determining heart disease risk.
Normal range for total cholesterol is below 200 mg/dL.
LDL (low-density lipoprotein) levels should be under 100 mg/dL (ideally lower).
HDL (high-density lipoprotein) levels are good when 40-60 mg/dL or higher.
Fasting is needed for accurate cholesterol measurement.
Fasting helps to ensure accurate cholesterol levels.
Blood samples are collected from a vein in the arm.
Elevated LDL cholesterol relates to plaque buildup in arteries, while HDL helps remove LDL from the bloodstream.
Regular monitoring is vital, especially for individuals with risk factors like family history or pre-existing conditions.
Lifestyle adjustments and medication may be necessary based on test results.

Glucose Testing

Fasting plasma glucose tests require an 8-hour fast.
Normal fasting plasma glucose is below 99 mg/dL.
2-hour postprandial plasma glucose should be under 140 mg/dL.
Random glucose levels should be below 180 mg/dL.
Glucose testing may diagnose diabetes or prediabetes (based on fasting or random levels).
Monitoring is important for diabetes management.
High glucose levels can signal underlying metabolic issues (metabolic syndrome or cardiovascular disease).
