[Automatic method for determination of serum antistreptolysin].

The AA. describe a method of determination of serum antistreptolysin employing "Technicon" AutoAnalyzer, this method permitting the execution of 40 determinations in an hour, with a time of analysis of about 16 minutes. The procedure of analysis is very easy, with a very high selectivity of values; a variation coefficient of 5,3% and an accuracy index of 4,4% were found. Since the amount of serum employed is 50 mul this method appears to be particularly suitable in paediatry and in serological screening.
