Here's an interesting case - look at the potassium and creatinine.

High potassiums are always suspect; were samples taken in the wrong order leading to EDTA contamination? In this case probably not - look at the (if anything) raised calcium. Creatinine is seriously up; GFR down. Renal failure?

Historically there has been raised creatinine.

Results were phoned; patient admitted, repeat samples sent. The patient *was* in renal failure
