Maximum urine concentration capacity was studied in healthy adults using different routes and doses of administration of 1-deamino-8-d-arginine vasopressin (DDAVP)-desmopressin. Plasma levels of DDAVP showed a dose-dependent increase after the subcutaneous but not after the intranasal administration. The effect on urine osmolality was similar but more(More)
According to international standards, reference values for biochemical tests should be obtained in disease-free subjects and for therapies that may influence measurement values. For elderly persons, especially the very old, such a requirement is difficult to meet, since few of these individuals are free of ongoing or former diseases. The present study of a(More)
The effect of different levels of fluid intake on the renal concentration test was evaluated. Maximal urinary osmolality did not significantly differ whether strict fluid restriction was kept or not. One side effect, namely headache, seemed more frequent after fluid deprivation than after a more liberal fluid intake. We suggest a practical approach to the(More)
OBJECTIVE To evaluate the NycoCard:::CRP test (Nycomed A/S, Oslo, Norway) in relation to ESR in consecutive patients in general practice. NycoCard:::CRP test was also compared with a reference method for CRP quantitation. DESIGN C-reactive protein and ESR were simultaneously measured in 607 consecutive patients at four community health centres. SETTING(More)
