Experimental: Open-label, single arm with identical assessment of both biomarkers for all participants
All participants will have their glycated nail keratin assessed by infrared and blood HbA1c levels measured via an assay (based on finger prick blood drop sample)
|
Device: Near-infrared (NIR)
NIR spectral assessment of glycated nail keratin vs glycated haemoglobin (HbA1c)
Other Name: point-of-care device (HbA1c analyser) |
- Accuracy of the Glyconics-SX System in detection of DM status based on dichotomised outcomes as per the chemometric model (HbA1c measurements as internal control) [ Time Frame: 60 seconds ]Overall probability of correct classification by the chemometric model output (yes / no DM)
- Assessment of sensitivity and specificity for chemometric model outcomes [ Time Frame: 60 seconds ]False positive and false negative assessments in %
- Calculation of negative and positive predictive value for the chemometric model [ Time Frame: 60 seconds ]Calculated values in %
- Calculation of area under the curve (AUC) with axis defined by false positive and negative rates (FPR, FNR) for the chemometric model [ Time Frame: 60 seconds ]Area under the curve value
- Median (IQR) HbA1c values in both groups (with or without diabetes) as measured by the comparative device [ Time Frame: 4 minutes ]HbA1c value in mmol/mol
- Analysis of safety outcomes (AEs, SAEs), including any safety outcomes listed in the comments, such as potential, suspected de novo diabetes diagnosis cases based on HbA1c readings [ Time Frame: 15 minutes ]Adverse events

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
- Apparently healthy adults (≥18 years of age) with known or unknown T2DM status willing to participate in and provide a written consent for the study
- willingness to undertake assisted assessment of glycaemia by both the NIR spectra measurement, and HbA1c by finger prick test
- Individuals with two visually assessed apparently healthy, undamaged, and intact fingernails, one in both right- and left-hand middle fingers
Exclusion Criteria:
-
Individuals with any known medical conditions impacting either of the assessment methodology for glycaemia, such as
- anaemia (iron deficiency sickle cell anaemia or similar)
- haemoglobinopathies or atypical haemoglobin subtypes not detectable by regular assays,
- severe renal impairment (CKD stage III-IV) or decompensated hepatic disease
- severe Vitamin D deficiency
- known severe immunodeficiency such as HIV, malignancy or other chronic condition significantly impacting assessment of glycaemia
- eating disorders (as per clinical assessment)
- Recent (within 28 days) blood donation
-
Any structural, deviating and visually detectable deviations in the appearance of the nails potentially impacting the spectra measurement, including
- nail dystrophy or deformity
- severe nail infections (onychomycosis causing visual changes in the appearance of the nail)
- rare hereditable conditions impacting the structure of keratin
- mechanical damage or marks on the surface of the nail after removal of nail polish
- use of acrylic or gel nail decoration and polish, which cannot be removed
- Any systemic or topical medication known to modify either the surface or structure of the nail or accuracy of HbA1c value.
