Initial complete blood count, electrolytes, coagulation, liver, and kidney function tests showed no abnormalities [Supplementary Table 1], but urine sodium dithionite test was positive [Figure 1]. An hour after hemodialysis the dithionite test was repeated and was slightly paler [Figure 1], however, due to a maintained positive dithionate test, hemodialysis was implemented for the second time for 8 h.
