Comparison of hKIM-1 and hKIM-1 levels normalized to creatinine concentration in urine of patients with renal tumors compared with normal patient urine^a

Group (n)	Absolute hKIM-1 (ng/ml)	Normalized hKIM-1 (ng/mg UCr)
Clear cell RCC (n = 21)	0.59 ± 0.16b	0.39 ± 0.08b
Non–clear cell renal tumor (n = 21)	0.27 ± 0.10c	0.24 ± 0.08c
papillary RCC (n = 5)	0.30 ± 0.27	0.14 ± 0.09
chromophobe RCC (n = 6)	0.23 ± 0.11	0.29 ± 0.18
unclassified RCC (n = 2)	0.14 ± 0.06	0.20 ± 0.16
other renal tumor (n = 8)	0.30 ± 0.19	0.28 ± 0.17
Normal (n = 30)	0.03 ± 0.01	0.05 ± 0.01

^aU_Cr, urinary creatinine concentration. Values are means ± SE.
