Articles dedicated to blood tests and other laboratory analyses: how to prepare properly, which markers truly matter, and how to interpret them in the context of your condition. A breakdown of key indicators, their interconnections, and hidden imbalances that may not be visible within standard “normal range” assessments. Learn how to use lab tests as a tool to understand processes in the body, identify the root causes of symptoms, and more precisely optimize your nutrition, lifestyle, and biohacking strategies.
Laboratory tests
When a person sees low ferritin or signs of anemia, the first thought is usually simple: iron is needed. Sometimes this is indeed the case. But blood, hemoglobin, and iron metabolism depend not only on iron stores. Vitamins B12, B9, B6, B2, and A are involved in the maturation of red blood cells, the synthesis […]
Taking tests often turns into a chaotic process: dozens of indicators without understanding what they mean. As a result, many resources are wasted, and there is almost no real information about health status.In practice, a minimal set of tests is sufficient to assess key systems: metabolism, deficiencies, inflammation, and the body's adaptation.Why you shouldn't take […]
Chronic inflammation is not an acute process with fever and pain, but a hidden condition that can develop for years without obvious symptoms. It is the underlying cause of most metabolic disorders, hormonal disruptions, and chronic diseases.The problem is that standard tests often do not reveal this condition. Leukocytes and basic indicators may remain normal […]
Defining deficiencies through tests is one of the most challenging tasks. The main mistake is trying to measure vitamins directly and draw conclusions from a single number. In practice, most vitamin tests do not reflect the actual situation in tissues.The body can maintain the levels of substances in the blood even with a pronounced deficiency […]
Glucose is the most popular test used to assess carbohydrate metabolism. However, it is often misleading. Normal glucose levels do not necessarily indicate that metabolism is functioning well, and elevated levels do not always signify a problem on their own.To truly understand the state of carbohydrate metabolism, one must look at the system: insulin, glycated […]
Lipidogram is one of the most commonly prescribed tests, but it is also one of the most misinterpreted. The main mistake is assessing total cholesterol without understanding the structure of lipid metabolism.Lipids in the blood are neither "bad" nor "good." They are a transport system that reflects how the body uses fats and energy. Therefore, […]
Protein metabolism is the foundation of tissue recovery, immune system function, hormonal balance, and detoxification. However, it is rarely measured directly in tests. Instead, indirect markers are used to understand how the body handles the synthesis and utilization of protein.The key mistake is to look at just one indicator. Protein metabolism is always assessed by […]
Tests are often perceived as objective truth: there is a number — therefore there is a diagnosis. But in practice, this is one of the most common mistakes. Most indicators reflect not the state of the body, but merely a snapshot of processes that can be compensated, distorted, or may not show a problem at […]
The coprogram is one of the most underrated tests. It is often perceived as a "general stool analysis," but in practice, it shows how the entire digestive system works: from the stomach to the intestines. It is important not just to look at individual indicators but to understand the processes behind them.General characteristics: what is […]
The gastropanel is a set of tests that allows for the assessment of the condition of the gastric mucosa without endoscopy. However, the results are most often interpreted simplistically: whether H. pylori is present or not.In practice, it is important to look at the combination of indicators, as their ratio reflects the function of the […]
