Experts from Sechenov University under the Ministry of Health of Russia have created a method for measuring total blood hemoglobin content in the body using palm transillumination. This method allows you to determine the total hemoglobin level in the blood instantly and without taking blood. This issue was told to socialbites.ca at the First Moscow State Medical University named after him. Sechenov.
A blood test for hemoglobin is necessary in the diagnosis of anemia and many other pathologies. Both hemoglobin deficiency and excess affect your health; Therefore, most examinations include a hemoglobin test. Typically this involves using the patient’s blood sample, so the procedure cannot be performed without a medical professional. Additionally, this method of taking blood tests does not allow for continuous monitoring.
Scientists have suggested an alternative option that is cheaper and does not require the patient’s blood to be drawn. The technology is based on evaluating changes in light intensity as it passes through large veins in the back of the hand. Absorption of oxygenated (i.e. bound to an oxygen molecule) and deoxygenated forms of hemoglobin in the near infrared range makes it possible to distinguish vessels from surrounding tissues.
“In this study, using experimental data and modeling data on the propagation of light in tissues, we were able to measure the error in determining the hemoglobin level using infrared imaging, taking into account various physiological parameters, such as the depth of blood vessels. Senior researcher at the Clinical Biophotonics Laboratory of Sechenov University and scientific and scientific research at the City Clinical Hospital “tissues, scattering parameters, melanin content in the skin and the volume fraction of blood in the dermis,” Boris Yakimov, an employee of the clinical department (CCH) No. 67, told socialbites.ca.
Scientists tested the method on nine volunteers who were examined in the emergency room of City Clinical Hospital No. 67. Measurements were made 10-15 minutes after venous blood was taken. The error in measurements was up to 17 g/l. In the future, accuracy could be improved by analyzing the variability of optical indicators of nearby areas across ships.
