New mo­bile tool mea­sures HB with­out draw­ing blood

Khaleej Times - - FRONT PAGE -

new york — Re­searchers have de­vel­oped a way to use smart­phone images of a per­son’s eye­lids to as­sess blood haemoglobi­n lev­els — a pro­tein in red blood cells that car­ries oxy­gen.

The abil­ity to per­form one of the most com­mon clin­i­cal lab tests with­out a blood draw could help re­duce the need for in-per­son clinic vis­its, the study, pub­lished in the Op­tica jour­nal said.

“Our new mo­bile health ap­proach paves the way for bed­side or re­mote test­ing of blood haemoglobi­n lev­els for de­tect­ing ane­mia, acute kid­ney in­jury and haem­or­rhages, or for as­sess­ing blood dis­or­ders such as sickle cell ane­mia.” said study re­searcher Young Kim from Pur­due Univer­sity in the US.

The re­search team used soft­ware to trans­form the built-in cam­era of a smart­phone into a hy­per­spec­tral imager that re­li­ably mea­sures haemoglobi­n lev­els. To per­form a blood haemoglobi­n mea­sure­ment with

the new tech­nique, the pa­tient pulls down the in­ner eye­lid to ex­pose the small blood ves­sels un­derneath. A health­care pro­fes­sional or trained per­son then uses the smart­phone app de­vel­oped by the re­searchers to take pic­tures of the eye­lids.

A spec­tral su­per-res­o­lu­tion al­go­rithm is ap­plied to ex­tract the de­tailed spec­tral in­for­ma­tion from the cam­era’s images and then an­other com­pu­ta­tional al­go­rithm quan­ti­fies the blood haemoglobi­n con­tent by de­tect­ing its unique spec­tral fea­tures. —
