Review: Non-invasive blood haemoglobin level measurement

摘要: Blood haemoglobin level measurement is an essential part of a global attempt at reducing anaemia. This review to elaborate on current advancements in non-invasive methods measure blood level. also elaborates established invasive for measuring and its role as reference standard. maps the wavelength used our observation control. The research team has obtained Journal or proceeding articles from Google Scholar Scopus using keyword "non-invasive haemoglobin" within titles 1980 2020. grouped by methods, those methods. There are 128 gathered keywords. 88 included this study. 26 light source combinations that developers use Most fits neatly window between 500 nm 1000 nm, where blood-haemoglobin-level control absorbance low. researcher 13 different commercially available. we have unregistered trials, majority unproven. We taking limitation. researchers should conduct further trial each method listed.
