(A) Correlation between cell content and integral of region 1.24 and 1.30 ppm of the 700 MHz CPMG 1H NMR spectra of saliva uncentrifuged and centrifuged at 750g, 1500g, 3000g, or 15 000g before a single freeze thaw cycle and quantified using external TSP (n = 39). (B) Correlation between choline concentration and epithelial cell concentration in uncentrifuged saliva after a single freeze thaw cycle and quantified using external TSP (n = 8).
