Serum water determination by means of microwave evaporation.
A novel method is described for the determination of serum water using a microwave oven. The sources of experimental errors were analysed. Serum samples from two hundred patients were analysed for sodium, water and protein, and the data were used to calculate serum sodium molalities. A possible correlation was investigated between serum water content and protein concentration. The results were compared with those in the literature.
