Argininemia at the moment of admission correlated significantly with glutaminemia [Pearson’s correlation coefficient (r) = 69.5 %, P = 0.0001], ornithinemia (r = 55.6 %, P = 0.006), C-reactive protein (r = 71.1 %; P = 0.006) and albuminemia (r = 70.1 %; P = 0.008). Here, CRP is linked to Argininemia.
