    Abstract:

    A total of 301 Black patients without rheumatic diseases was studied to estimate the prevalence and causes of positive rheumatoid factor. The latex slide test was positive in 25% of patients and 21% had a 'diagnostic' titre of 80 or more. A significant relationship between gamma-globulin levels and rheumatoid factor positivity was demonstrated. IgG appeared to be the most important in determining this relationship. The most common ailments among sero-positive patients were cirrhosis and tuberculosis.
