A method of determining dermal calcium losses in connection with calcium balance studies is described. The method involves collection of arm sweat in a plastic bag, rinsing with deionized water, determination of the Ca K ratio in the diluted sweat, and determination of dermal potassium losses. The latter losses are determined on the basis of the potassium balance and simultaneous determinations of changes in total exchangeable potassium. Arm sweat seems to be representative for whole body sweat with respect to the Ca K ratio. The dermal calcium loss varied between 20 and 365 mg. in 13 patients (mean 120 mg./day). These losses are of considerable importance in connection with calcium balances which is illustrated in a number of cases. |
