[Extraction of LHRH in human urine: study of the extraction of labelled synthetic hormone].
A method of extraction of synthetic LHRH is studied in human urines, using porous glass (Spherosil) and methanol. In the defined conditions the yield is greeter than 80%. It appears that the method is reproducible. The recovery varies essentially with the quantity of Spherosil and the pH of methanal. The use of methanol acidified at pH 3 increases the speed and the importance of labelled LHRH recovery.
