Dear colleagues, With the persistent warm weather in our country we think we see more low values for magnesium than usually (even down to 0.43 and 0.32 mmol/L in two patients this week). An increased tubular flow (increased drinking) is a risk factor for urinary loss of magnesium. What is your experience? Are suffering from selectian bias?
