What diseases can be detected through a serum blood test?

Generally speaking, serum testing refers to serological examination. Serological tests can detect diseases such as anemia, hyperlipidemia, diabetes, hepatitis B, and systemic lupus erythematosus. Detailed analysis is as follows:

1. Anemia

Blood serum tests can measure indicators such as red blood cell count and hemoglobin concentration to determine the presence of anemia. Anemia is a condition characterized by insufficient quantity or quality of red blood cells in the blood, leading to tissue hypoxia.

2. Hyperlipidemia

Serum lipid levels, including total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein, are important indicators for assessing lipid status. Abnormally elevated levels of these indicators may suggest hyperlipidemia, which is an important risk factor for cardiovascular disease.

3. Diabetes

Serum testing can measure blood glucose levels, which is the main basis for diagnosing diabetes. When fasting blood glucose or blood glucose levels two hours after a meal exceed the normal range, it may indicate diabetes. Diabetes is a metabolic disease, and long-term high blood glucose levels can damage multiple organs in the body.

4. Hepatitis B

Hepatitis B is a liver disease caused by the hepatitis B virus. Serological testing can detect indicators such as hepatitis B surface antigen and hepatitis B e antigen, whose presence indicates that the patient has been infected with the hepatitis B virus. Additionally, indicators such as hepatitis B core antibody can be tested to understand the patient's immune status and disease progression.

5. Systemic Lupus Erythematosus (SLE)

Systemic lupus erythematosus is an autoimmune disease that can affect multiple organ systems throughout the body. Serological testing can detect various autoantibodies, such as antinuclear antibodies and anti-double-stranded DNA antibodies. The presence of these antibodies is significant for the diagnosis of systemic lupus erythematosus.

Maintaining a balanced diet, engaging in moderate exercise, ensuring adequate sleep, and avoiding excessive fatigue in daily life are all beneficial for maintaining good health.
