Blood test for home use

Blood tests are a central component of modern medicine and provide valuable insights into a person’s state of health. They make it possible to monitor various health parameters, recognise diseases at an early stage and detect deficiencies. Determining the micronutrient status is particularly important, as vitamins, minerals and fatty acids play a crucial role in physical and mental health.

A balanced micronutrient balance is essential for numerous bodily functions, including the immune system, energy production and cell regeneration. A deficiency of certain micronutrients can lead to a variety of health problems, from fatigue and poor concentration to serious illnesses. It is therefore important to regularly check your micronutrient status and take targeted countermeasures if necessary. In this article, we will shed light on the importance of blood tests to determine micronutrient status and give you an overview of traditional and modern methods of blood sampling and analysis.

Why are blood tests important?

General importance of blood tests in medical diagnostics

Blood tests are one of the basic methods in medical diagnostics. They offer a non-invasive way of obtaining important information about a person’s state of health. By analysing blood samples, doctors and specialists can diagnose a variety of diseases, monitor health status and assess the success of treatments. Blood tests are essential for detecting infections, monitoring organ function and identifying metabolic disorders.

What information do blood tests provide?

Blood tests can provide a wealth of information that is crucial for the diagnosis and treatment of disease:

• Blood glucose levels: Monitoring and diagnosis of diabetes.
• Cholesterol levels: assessment of the risk of cardiovascular disease.
• Liver and kidney values: assessment of the function of these vital organs.
• Blood count: Analysis of the number and composition of red and white blood cells and platelets to detect anaemia, infections and blood clotting disorders.
• Electrolytes and minerals: Determination of the balance of electrolytes such as sodium, potassium and calcium, which are important for many bodily functions.
• Hormone levels: Checking the function of endocrine glands and diagnosing hormonal imbalances.
• Inflammatory markers: Detection of inflammation in the body, which can indicate infections or chronic diseases.

How can blood tests help to recognise and prevent deficiencies?

A major advantage of blood tests is the ability to recognise deficiencies at an early stage and take targeted measures to correct them. Micronutrients such as vitamins, minerals and fatty acids are crucial for numerous bodily functions. A deficiency of these nutrients can lead to a variety of health problems.

• Detection of vitamin deficiencies: Blood tests can determine the status of important vitamins such as vitamin D, B12 and folic acid. Deficiencies in these vitamins can lead to bone weakness, anaemia and neurological disorders.
• Monitoring of minerals: Analysing blood levels of minerals such as magnesium, zinc and calcium helps to identify deficiencies that can cause muscle cramps, weakness and bone loss.
• Determination of fatty acids: The omega-3 index and the ratio of omega-6 to omega-3 fatty acids are important indicators for the health of the cardiovascular system and inflammatory processes in the body.

Regular blood tests allow deficiencies to be recognised at an early stage and corrected in a targeted manner by adjusting the diet or taking supplements. This helps to prevent long-term health problems and improve general well-being.

Which micronutrients are crucial?

Important vitamins

Vitamins are organic compounds that the body needs in small amounts to maintain a variety of functions. Here are some of the most important vitamins and their roles in the body:

• Vitamin A: Essential for vision, the immune system and skin health. A deficiency can lead to night blindness and increased susceptibility to infections.
• Vitamin D: Important for calcium and phosphate absorption, bone and dental health and the immune system. A vitamin D deficiency can cause osteoporosis, muscle weakness and an increased risk of infection.
• Vitamin B12: Plays a crucial role in the production of red blood cells, DNA synthesis and the function of the nervous system. A deficiency can lead to anaemia, fatigue and neurological disorders.
• Vitamin C: A powerful antioxidant that protects cells from oxidative stress, boosts immune function and supports collagen formation. A deficiency can lead to scurvy, weak connective tissue and an increased risk of infection.
• Vitamin E: Protects cells from damage caused by free radicals and supports skin health. A deficiency can lead to neurological problems and skin changes.

Important minerals

Minerals are inorganic substances that are necessary for numerous bodily functions. Some of the most important minerals include

• Magnesium: Involved in over 300 enzymatic reactions in the body, including energy production, protein synthesis and muscle and nerve function. A deficiency can cause muscle cramps, fatigue and cardiac arrhythmia.
• Zinc: Important for the immune system, wound healing, cell metabolism and DNA synthesis. A deficiency can lead to growth retardation, hair loss and a weakened immune system.
• Calcium: Essential for bone health, muscle contractions and blood clotting. A deficiency can lead to bone weakness, muscle cramps and increased risk of osteoporosis.
• Iron: Essential for oxygen transport in the blood and energy production. A deficiency can lead to anaemia, tiredness and reduced performance.
• Selenium: An antioxidant that protects cells from oxidative stress and supports the immune system. A deficiency can lead to thyroid problems and a weakened immune system.

Important fatty acids and their significance

Fatty acids are essential components of the diet that are necessary for cell membrane structure and various bodily functions. The two most important groups are omega-3 and omega-6 fatty acids:

• Omega-3 fatty acids: These polyunsaturated fatty acids, such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are crucial for heart health, brain function and inflammation regulation. They are mainly found in oily fish, linseed and walnuts. A deficiency can lead to cardiovascular disease, inflammatory diseases and cognitive impairment.
• Omega-6 fatty acids: These fatty acids, such as linoleic acid, are also important for health, but must be consumed in a balanced ratio to omega-3 fatty acids. They are found in vegetable oils such as sunflower and corn oil. An imbalance can promote inflammatory processes in the body.
• Omega-3 to omega-6 ratio: A balanced ratio of these fatty acids is important to regulate inflammation and minimise the risk of chronic disease. Ideally, the ratio of omega-6 to omega-3 in the diet should be around 4:1 or lower.

Regularly checking and optimising micronutrient status through blood tests can help to identify deficiencies at an early stage and take targeted measures to maintain and improve health.

Traditional methods of blood collection and analysis

Venous blood sampling in the doctor’s surgery

The traditional method of blood collection is usually carried out in a doctor’s surgery or medical laboratory. Venous blood is drawn, usually from a vein in the crook of the arm. This method allows for the collection of a sufficient amount of blood to perform a variety of tests.

Venous blood sampling process:

• The patient sits or lies comfortably.
• The blood collection site is disinfected.
• A tourniquet is placed around the upper arm to visualise the vein.
• A needle is inserted into the vein and the blood is collected in one or more tubes.
• After collection, the needle is removed and a plaster is applied to the puncture site.

Advantages and disadvantages of traditional methods

Advantages:

• Volume of blood: venous blood sampling allows large volumes of blood to be collected, which is necessary for extensive and detailed analyses.
• Accuracy and reliability: Analysing venous blood is considered to be very accurate and reliable, as larger blood samples allow for more precise measurement.
• Wide range of tests: venous blood can be used for a variety of tests, including biochemical, haematological and immunological tests.

Disadvantages:

• Invasiveness: venous blood sampling is more invasive and can be uncomfortable or scary for some patients.
• Time required: Visiting a doctor’s surgery or laboratory takes time and planning.
• Cost: The cost of blood collection and subsequent testing can be higher than less invasive methods.
• Access: In rural or underserved areas, access to medical facilities may be limited.

Common methods of analysis and their areas of application

Various analytical methods are used to obtain specific information from blood samples. Here are some of the most common methods and their areas of application:

• Blood count (haemogram): This method analyses the number and type of blood cells (red and white blood cells, platelets). It is used to diagnose and monitor anaemia, infections, inflammation and blood clotting disorders.
• Biochemical analysis: Measures various chemicals in the blood, including glucose, electrolytes, enzymes, lipids and proteins. These tests help to assess the condition of the liver, kidneys, heart and other organs.
• Immunological tests: Examine antibodies and antigens in the blood to diagnose infections, autoimmune diseases and allergies. These include tests such as the ELISA (enzyme-linked immunosorbent assay) and the Western blot.
• Hormone analyses: Measure the concentrations of hormones such as thyroid hormones, sex hormones and stress hormones. These tests are used to diagnose hormonal imbalances and endocrine disorders.
• Blood coagulation tests (coagulogram): Assess the blood’s ability to clot by measuring parameters such as prothrombin time (PT) and activated partial thromboplastin time (aPTT). These tests are important for patients with blood clotting disorders or before surgical procedures.
• Micronutrient analyses: Determine the concentrations of vitamins, minerals and trace elements in the blood. They help to recognise deficiencies and develop targeted nutritional or supplementation strategies.

Traditional methods of blood sampling and analysis offer a comprehensive way of obtaining detailed information about the state of health. Despite some disadvantages such as invasiveness and time-consumingness, they remain an important part of medical diagnostics and health monitoring.
