Sweat diagnostics

Sweat diagnostics is an emerging <a href="/facts/Medical_test/rRgnuQSD">non-invasive technique</a> used to provide insights to the health of the human body. Common <a href="/facts/Perspiration/c5zARtaT">sweat</a> diagnostic tests include testing for <a href="/facts/Sweat_test/byX4dRX8">cystic fibrosis</a> and <a href="/facts/Illicit_drugs/eaTugrky">illicit drugs</a>. Most testing of human sweat is in reference to the <a href="/facts/Eccrine_sweat_gland/QrJPP1J5">eccrine sweat gland</a> which in contrast to the <a href="/facts/Apocrine_sweat_gland/W22aII18">apocrine sweat gland</a>, has a lower composition of oils.
Although sweat is mostly water, there are many solutes which are found in sweat that have at least some relation to <a href="/facts/Biomarkers/nk2LgXtq">biomarkers</a> found in blood. These include: <a href="/facts/Sodium/eYuSPu2V">sodium</a> (Na+), <a href="/facts/Chloride/m9NUaUDR">chloride</a> (Cl−), <a href="/facts/Potassium/FWPwS7Rj">potassium</a> (K+), <a href="/facts/Ammonium/jYm8wc1n">ammonium</a> (NH+4), <a href="/facts/Alcohol_(chemistry)/Y0SCTDkh">alcohols</a>, <a href="/facts/Lactic_acid/BsVRFx7s">lactate</a>, <a href="/facts/Peptide/C4ltc7UG">peptides</a> & <a href="/facts/Protein/Jxmagu3E">proteins</a>. Development of devices, sensing techniques and biomarker identification in sweat continues to be an expanding field for medical diagnostics and athletics applications.
The use of smart biosensors for on-skin sweat analysis has been described as internet-enabled Sudorology (iSudorology) by Brasier et al. in 2019. It describes the lab-independent detection of molecular, next-generation digital biomarkers in sweat.
