2020: The announcement of the device for measurement of cortisol from ear Trears sulfur
In the middle of November, 2020 researchers from University college and Royal college of London announced use of the Trears device prednaznachyaenny for sampling of ear sulfur for the purpose of measurement of level of cortisol. At the same time the patient can use the device without involvement of the medic at home.
Concentration of cortisol changes at patients with such statuses as a depression, Addison's disease and Cushing's syndrome therefore measurement of level of this hormone can be useful to diagnostics and monitoring of these diseases. However cortisol level in blood can strongly fluctuate, and blood samples not always allow to estimate it precisely. Moreover, methods of sampling can be called a stress at the patient and by that to affect analysis results.
Other option - to measure cortisol level in ear sulfur. Kind of unattractively this method sounded, concentration of cortisol in ear sulfur is stabler, and use of the new device allows to take easily and safely a sample for the fast, cheap and effective analysis.
Syringing is considered a standard method of receiving samples of ear sulfur, but it is rather discomfortable procedure which should be held in clinic. It is supposed that new approach using special will be more simply and quicker, and the patient will be able to perform independently the procedure at home.
The new device reminds a colourful wadded tampon, but its construction does not allow the patient to advance it too far to the ear canal, thereby preventing accidental injury of an eardrum and other structures. The tip of the device is covered with the cellulose sponge impregnated with solution of mineral oil with magnesium chloride which absorbs ear sulfur.
Researchers tested the device on volunteers and proved that the received samples of ear sulfur serve as reliable material for the analysis of cortisol.[1]
