Attenuated total reflection Fourier‐transform infrared ( ATR ‐ FTIR ) spectroscopy to diagnose osteoarthritis in equine serum

Reliable and validated biomarkers for osteoarthritis (OA) are currently lacking.To develop an accurate and minimally invasive method to assess OA-affected horses and provide potential spectral markers indicative of disease.Observational, cross-sectional study.Our cohort consisted of 15 horses with OA and 48 without clinical signs of the disease, which were used as controls. Attenuated total reflection Fourier-transform infrared (ATR-FTIR)...
