  • Electrocardiography (ECG)

    Electrocardiography is the study of the bioelectrical activity of the heart. Every living cell of the heart is a source of electrical energy. An ECG records changes in electrical voltages in the heart muscle. The currents generated in the heart pass through the tissues and can be recorded and stored in the form of an […]

  • Electroencephalography (EEG)

    Electroencephalography EEG is a method of recording the functional currents produced in the brain. The EEG apparatus is equipped with special electrodes, which are placed on the head. These electrodes record changes in the potential of bioelectrical currents in the brain. The EEG enables to differentiate between organic and functional brain diseases. It allows to […]

  • Exercise ECG (stress test)

    Exercise stress testing is the evaluation of ECG changes during exercise. The ECG is known to change during exercise both physiologically and in disease states. Exercise testing primarily assesses the physical capacity of the body. Simultaneous ECG monitoring and blood pressure measurement during exercise allow assessment of cardiovascular fitness. Preparation for the exercise test Prior […]

  • Echokardiography

    Echocardiography is an ultrasound examination of the heart. (It uses ultrasound.) The machine sends ultrasound sounds through a special transducer, which are reflected from structures inside the body and recorded by the same transducer, and then processed into an image, the so-called echo. This is a non-invasive examination. This examination allows for the evaluation of […]

  • Biopsy

    A biopsy is an invasive method of examination that involves taking cells from diseased tissue. The material for examination is usually taken with a needle. After the biological material is taken, it is evaluated under a microscope (histopathological examination). Biopsy examination allows for accurate evaluation of lesional tissues. Biopsies are used to examine: liver, kidney, […]

  • Blood test – interpretation of results

    A blood test is one of the basic tests most often recommended by doctors. Its results allow assessment of the patient’s general health condition and, if necessary, allow to plan an appropriate treatment. Peripheral blood is taken from the blood vessels, mainly capillaries, arteries and veins. Peripheral blood is collected from the blood vessels, mainly […]

  • Blood tests – Morphology

    Blood is a very important component of the human body. It makes up about 7% of the body weight, so in an adult it corresponds to 5 liters. Most of the blood is plasma (55% by volume). The most important function of blood is to supply oxygen, hormones, nutrients and enzymes to every cell in […]

  • DNA testing

    The bottom line for humans is that DNA testing can be used for diagnostic purposes for many diseases. These tests involve taking a material, which is usually blood, and detecting various mutations, or errors, in it. In recent years, we’ve been hearing a lot about DNA and related concepts such as gene, mutation, and cloning. […]

  • Angiografia

    Angiography is a method of examining blood vessels to accurately assess changes inside the vessels. It is based on X-rays. Since ordinary X-rays do not show the inside of the blood vessels well, a suitable contrast is used. The contrast fills the vessels and strongly absorbs the X-rays, making it visible on the images as […]
