An interesting case - the serum sodium was rather high; a chloride was then performed and found to be normal.

This result is rather implausible - high sodium goes with high chloride; not with normal ones. Bearing in mind the source of the blood sample (renal dialysis unit) it is likely that the blood sample has been contaminated with citralok.

Citralock is something used to keep various infusion lines clear. Finding out about citralock made for interesting reading
