“…35 Meanwhile, findings from studies that reported improvement in diagnosis sensitivity and specificity by applying machine learning to the multi-biomarker analysis have been used in real-world cases to classify the cancer-related biomarkers; moreover, machine learning has been applied in cases of in-vitro diagnosis of diseases such as tuberculosis and dementia. 36 37 38 39 …”

“…Based on such GC-MS approaches, a limited number of VOCs has been tentatively identified as part of a volatile lung cancer profile [19,31,43,[45][46][47][48][49][50]. However, because of the limited peak capacity and sensitivity of GC-MS, but also because of the lack of robustness, quality control, and validation of sampling and analysis, the approach has not yet found its way to clinical application [51]. Peak capacity and sensitivity can be enhanced by using comprehensive twodimensional gas chromatography coupled to time-of-flight MS (GC×GC-TOFMS), a known efficient separation technique for complex sample analysis [51][52][53].…”

“…However, because of the limited peak capacity and sensitivity of GC-MS, but also because of the lack of robustness, quality control, and validation of sampling and analysis, the approach has not yet found its way to clinical application [51]. Peak capacity and sensitivity can be enhanced by using comprehensive twodimensional gas chromatography coupled to time-of-flight MS (GC×GC-TOFMS), a known efficient separation technique for complex sample analysis [51][52][53]. Basically, GC×GC relies on the use of two different GC phases connected in series via a modulator [54] that, when using cryogens to operate, not only enhances the separation power but also provides better limits of detection by cryogenic zone compression of chromatographic peaks [55].…”

“…Numerous research teams had utilized gas chromatography (GC) interrelated to mass spectrometry (MS), for inspecting the volatile molecules detected in breath in cases with active pulmonary TB, and detected diverse forms of marker compounds [4] [5] [6] owing to different sampling methods and analytical approaches along with patient population heterogeneity and patient comorbidities [7].…”
