A significant portion of carriers are asymptomatic and undiagnosed posing complications in the eradication of malaria as it restricts the types of drugs used for malaria treatment. A simple and accurate diagnosis of the deficiency is vital in the eradication of malaria. In this study, we investigate the potential of attenuated total reflection Fourier transform infrared spectroscopy (ATR FT-IR) as a diagnostic technique for G6PD deficiency. Venous blood samples were collected in lithium heparin anticoagulant tubes from G6PD partial and fully deficient volunteers, n\u2009\u2009=\u2009\u200917, and normal volunteers, n\u2009\u2009=\u2009\u200959, in Khon Kaen, Thailand. Spectra of aqueous and dry samples were acquired of whole blood, plasma, and red blood cells, and modeled using partial least squares discriminant analysis (PLS-DA). PLS-DA modeling resulted in a sensitivity of 0.800 and specificity of 0.800 correctly classifying fully deficient participants as well as a majority of partially deficient females who are often misdiagnosed as normal by current screening methods. The viability of utilizing aqueous samples has always been hindered by the variability of hydration in the sample, but by employing multicurve curve resolution-alternating least squares to subtract water from each sample we are able to produce high-quality spectra with minimized water contributions. The approach shows proof of principle that ATR FT-IR combined with multivariate data analysis could become a frontline screening tool for G6PD deficiency by improving tailored drug treatments and ultimately saving lives.<\/jats:p>","DOI":"10.1177\/00037028231170851","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T03:40:15Z","timestamp":1684467615000},"page":"513-520","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Identification of Glucose-6 Phosphate Dehydrogenase Deficient Patients Using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy Using Partial Least Squares Discriminant Analysis in Aqueous Blood Samples"],"prefix":"10.1177","volume":"77","author":[{"given":"Miguela","family":"Martin","sequence":"first","affiliation":[{"name":"Centre for Biospectroscopy, Monash University, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8494-4142","authenticated-orcid":false,"given":"Molin","family":"Wongwattanakul","sequence":"additional","affiliation":[{"name":"Faculty of Associated Medical Sciences, Khon Kaen University, Muang Khon Kaen, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noppmats","family":"Khemtonglang","sequence":"additional","affiliation":[{"name":"Faculty of Associated Medical Sciences, Khon Kaen University, Muang Khon Kaen, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pakaphan","family":"Kiatchoosakun","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, Khon Kaen University, Muang Khon Kaen, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip","family":"Heraud","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Medicine, Nursing and Health Sciences, Monash University, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patcharee","family":"Jearanaikoon","sequence":"additional","affiliation":[{"name":"Faculty of Associated Medical Sciences, Khon Kaen University, Muang Khon Kaen, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3581-447X","authenticated-orcid":false,"given":"Bayden R.","family":"Wood","sequence":"additional","affiliation":[{"name":"Centre for Biospectroscopy, Monash University, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,5,19]]},"reference":[{"key":"bibr1-00037028231170851","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1001339"},{"key":"bibr2-00037028231170851","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-407826-0.00004-7"},{"issue":"2","key":"bibr3-00037028231170851","first-page":"75","volume":"30","author":"Tanphaichitr V.","year":"1999","journal-title":"Southeast Asian J.
