A MICRO METHOD FOR BLOOD UREA AND AN AUTOMATIC URINE COLLECTOR FOR UREA CLEARANCE IN INFANTS

Blood urea clearance in young Indonesian subjects.

Urea clearance was determined on 25 healthy male medical students at Surabaja, Indonesia. The age of the subjects varied from 20 to 25 years, the average being 23 years.

A Direct Colorimetric Method for the Determination of Urea in Blood and Urine

A simple spectrophotometric method for the determination of urea in blood and urine.

Several methods for determining urea in blood and urine are in use in clinical laboratories, but none is ideal in mass routine analysis. The spectrophotometric method based on a modified Ehrlich reagent proposed by Watt and Chrisp (1954) for pure solutions is therefore of interest because it can be modified for use in mass clinical analyses of blood and urine. Brown (1959) has modified the meth...
