One hundred and eleven (111) blood specimens were collected from patients with known or suspected syphilis by venipuncture and on a small piece of No. 3 grade filter paper. Both specimens from each patient were tested by fluorescent treponemal antibody absorption (FTA-ABS) test. Of the 62 patients whose venipuncture sera were FTA-ABS positive, filter paper blood samples were also positive in 56 (90%) and negative in 6 (10%). Complete agreement was obtained on paired specimens from 49 patients who were FTA-ABS negative. These preliminary results suggest that finger stick blood samples, collected on filter paper, could be used for FTA-ABS testing of remote rural populations—such as in areas where yaws is endemic.
