摘要
The presence of phenolsulphonphthalein (PSP) in urine is automatically determined by the addn. of an equal quantity of an alkaline colour reagent soln. to develop the colour in a 100% soln. The same alkaline soln. is added to urine samples taken from a patient over a series of time intervals. The reagent should have pigments stable in alkaline soln. The absorption for various wavelengths is then measured. The concn. is then calculated by a microprocessor which calculates the amt. of PSP passed by the patient over the time intervals involved. For use in checking the kidney and blood circulation of a patient by intravenous injection of PSP. Allows the urine samples subsequently collected to be automatically analysed.
