title: Streptokinase resistance test in a group of Mediterranean people and its possible variations as regards sex and age.
abstract: A streptokinase resistance test (SK-RT) was studied on a group of people from the Mediterranean coast of Spain. It was found that 87.5% of the studied population required a dose of 250,000 U or less to obtain an adequate neutralization of the circulating antibodies. In none of the cases was the required dose higher than 500,000 U. The average dose was of 132,969 U (SD = 102,269). No significant differences were found between the dose required for men and that required for women. A significantly inferior dose to the average was, however, required for people over 50 years old (x = 112,280, SD = 100,459).
