Stepwise regression equations relating plasma or erythrocyte magnesium and other variables in insulin-dependent and non-insulin-dependent diabetics.

NADH concentration will produce an upward curve deflection. Bubble traps have been inserted prior to the pumps on the NADH reagent lines. The trap has been constructed from an Y-shaped glass tube, mounted upside-down, with its top connected to a piece of soft polyethylene tube, closed by a clamp. This tube will collect bubbles. Each morning, it must be refilled with fresh reagent by aspiration. In our SMAC analyzer, rerun frequency is reduced by 3% on each of the two channels.
