Test Test

Cholesterol is a fat-like substance that is needed in the body for the production of cell membranes, hormones, and bile acids. The laboratory value measures the concentration of total cholesterol in the blood, which consists of LDL cholesterol, HDL cholesterol, and other lipoproteins.

A cholesterol test is recommended for: Persons with a family history of cardiovascular diseases People with overweight, diabetes or high blood pressure Persons with unhealthy eating habits (e.g. high-fat diet) Patients with existing cardiovascular diseases for monitoring People over 40 years of age as a preventive check-up

The test serves to assess the risk of cardiovascular diseases such as atherosclerosis, heart attack or stroke. It is also used to monitor the effect of medications such as statins or changes in lifestyle.

A high cholesterol level can indicate an increased risk of cardiovascular disease. Symptoms of a significantly elevated value often do not appear until late and include: Angina pectoris (chest pain) Dizziness or shortness of breath during exertion A low cholesterol level is rare and is usually caused by malnutrition or certain liver diseases.

The test should ideally be performed fasting in the morning, as food intake can temporarily affect cholesterol levels.

Total cholesterol alone is less informative than the ratio of LDL to HDL. Regular exercise and a balanced diet can positively influence cholesterol levels. If there is a suspicion of genetically determined lipid metabolism disorders, further tests such as lipoprotein A can be helpful.

Vitamin B9, also known as folate or folic acid, is a water-soluble vitamin that plays a crucial role in cell division, DNA synthesis, and blood formation. The laboratory value measures the concentration of folate in the serum.

A Folat test is particularly suitable for: Pregnant women or women who wish to have children (to prevent neural tube defects in the fetus) People with signs of anemia (e.g. fatigue, paleness) Persons with chronic intestinal diseases (e.g. celiac disease, Crohn's disease) Alcoholics or people with inadequate nutrition Older people suspected of nutrient deficiency

The test helps to diagnose a folate deficiency, which is often the cause of megaloblastic anemia. This form of anemia leads to an enlargement of the red blood cells and reduced cell division ability. Furthermore, vitamin B9 is essential for the prevention of neural tube defects during pregnancy.

A low folate value indicates inadequate intake or absorption disorder. A deficiency can show the following symptoms: Fatigue and weakness Concentration difficulties Paleness and shortness of breath Increased risk of malformations in the unborn child (e.g. spina bifida) An elevated value is rare, but can occur due to excessive supplementation.

The testing should be carried out in case of symptoms such as anemia or chronic fatigue. Women with a desire to have children or pregnant women should have their folic acid status checked early, ideally before conception or at the latest in the first trimester. The testing can be carried out at any time of the day and is independent of food intake.

Folic acid is the synthetic form of folate and is better absorbed by the body, which is why it is often used in dietary supplements and fortified foods. Chronic folate deficiency can lead to an increased homocysteine level, which is a risk factor for cardiovascular diseases. Alcohol and certain medications (e.g. methotrexate) can reduce the body's absorption of folate.
