Hemoglobinometry

A hemoglobinometer is a medical device that is used to measure the amount of hemoglobin in the blood. Hemoglobin is a protein that carries oxygen throughout the body and is involved in respiration processes.

The hemoglobinometer can be used in various medical studies, such as diagnosing anemia, monitoring the effectiveness of treatment for blood diseases and assessing the condition of patients with chronic lung diseases.

The operating principle of the hemoglobinometer is based on the reaction between blood hemoglobin and a dye, which changes its color depending on the amount of hemoglobin. As a result of this color change, the hemoglobin concentration in a blood sample can be determined.

The hemoglobinometer can be either manual or automatic. A handheld hemoglobinometer uses a special solution that mixes with blood and changes color when it comes into contact with hemoglobin. An automatic hemoglobinometer works on the basis of spectrophotometry, where a blood sample is placed in a special container and then passed through a laser beam, which changes its color according to the hemoglobin concentration.

It is important to note that the accuracy of a hemoglobinometer measurement depends on many factors, such as the quality of the blood sample, the temperature and lighting of the room where the measurement is performed, etc. Therefore, certain rules and procedures must be followed to obtain accurate results.

Hemoglobinammetry is an analytical method for determining the concentration of hemoglobin in the blood. The method is based on the reaction of hematin oxalate with oxygen. The higher the hemoglobin concentration, the more intense the reaction. To determine hemoglobin concentration, the amount of oxygen absorbed or released by a solution of an oxalate mixture is measured. The oxalate preparation is administered by mouth or instilled into the stomach. The reaction time is counted from the moment the drug is administered, and in addition to calculating the amount of oxygen absorbed, the pH of the stomach and the pressure gauge are measured, which allows you to check hemodynamics and the amount of bleeding. The normal criterion is a reaction time of at least 5 minutes.
