Weigerta-Paglia Method

The Weigert–Pahl method is a method for studying blood cells that was developed in the 19th century by German scientists Karl Weigert and Joseph Pahl. This method is used to determine the number of red blood cells, white blood cells and platelets in the blood.

The essence of the method is that blood is placed in a special solution, which allows the blood cells to be separated into individual components. These components are then stained with special dyes and the number and shape of each cell can be seen under a microscope.

The Weigert-Pahl method is one of the simplest and most accessible blood testing methods. It is widely used in clinical practice to diagnose various blood diseases such as anemia, leukemia and thrombocytopenia.

However, this method has its limitations and cannot be used for all types of blood cells. Also, results may not be accurate if the blood sample was collected incorrectly or if the cells were damaged during storage.

Thus, the Weigert-Pahl method remains an important tool in the diagnosis of blood diseases, but its use should be based on a thorough analysis of all possible factors that may affect the results of the study.

Weigert-Pahl method, a complex method of contrast-color or disproportionate contrast, named after the authors: Professor Konstantin Fedorovich Weigert (1847–1921) and gynecologist Johann Pahl (1864–1934). The technique is based on the introduction of various “confusing” chemicals into the bloodstream. In this case, the total amount of blood remains unchanged or increases slightly, and the difference in the volume of current is determined by the volume of the substance injected into the peripheral artery.
