Introduction

In general, cholesterol levels can be assessed through methods such as venous blood draw, blood viscosity tests, ultrasound (B-ultrasound), urine tests, and CT coronary angiography. If test results show abnormalities, it is recommended to seek medical attention promptly to avoid delaying treatment. Maintaining healthy lifestyle habits in daily life is beneficial for overall health.

Under normal circumstances, cholesterol levels can be assessed through methods such as venous blood draw, blood viscosity testing, ultrasound (B-ultrasound), urine tests, and CT coronary angiography. Specific details are as follows:

1. Venous Blood Draw

Cholesterol testing typically involves drawing blood from a vein to measure lipid levels. However, fasting is required before the test—patients should avoid eating or drinking for at least 8 hours prior to the examination.

2. Blood Viscosity Testing

Blood viscosity testing helps determine the thickness or stickiness of the blood, thereby identifying potential lipid abnormalities.

3. B-ultrasound

B-ultrasound can examine the structure and function of the heart and major blood vessels, including arterial wall thickness and blood flow velocity. This test helps assess the extent of atherosclerosis and overall circulation.

4. Urine Test

Urine testing provides preliminary information about levels of uric acid and cholesterol. Elevated levels of uric acid and cholesterol in urine may suggest gout.

5. CT Coronary Angiography

This non-invasive test uses computed tomography (CT) scanning to visualize the coronary arteries and evaluate the degree of narrowing or blockage. It provides detailed images of the heart's arterial condition.

If any abnormal results are detected, prompt medical consultation is recommended to prevent delays in diagnosis and treatment. Maintaining healthy lifestyle habits in daily life is beneficial for overall health.
