Washing Method, an Accurate Detection Method of Urinary Nanocrystallites to Eliminate Interference of Soluble Components in Urine

Abstract:

Using X-ray power diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), the chemical composition of urinary nanocrystallites from 3 calcium phosphate (CaP) stone-formers were investigated and compared with that from healthy subjects. The main components of nanocrystallites in urine of CaP stone formers were uric acid and CaP, while that in healthy urine was mainly uric acid, which indicated a significant difference. This study purposed an accurate detection method of urinary nanocrystallites, namely washing the urinary crystallites samples with double distilled water, which can avoid the interference of soluble components (such as NaCl, uric acid, and urea) that were precipitated from urine during sample preparation.
