Table 3 Comparison between LC-MS, uricase-based, and HumaSensplus uric acid (UA) measurements

From: Accuracy of the HumaSensplus point-of-care uric acid meter using capillary blood obtained by fingertip puncture

  Mean ± SD (μmol/l)
Plasma LC-MS UA (n = 67) 292.07 ± 80.64
Plasma uricase UA (n = 67) 304.46 ± 90.14
HumaSensplus capillary UA (n = 67) 291.64 ± 82.60
Δ Plasma LC-MS – plasma uricase UA −12.39 ± 22.30 (p < 0.0001)
Δ Plasma LC-MS – HumaSensplus capillary UA −0.43 ± 46.19 (p = 0.93)
