Routine blood tests performed in most Alaska laboratories are either the Rapid Plasma Reagin (RPR) or VORL antigen tests. These nontreponema1 antigen tests are used for syphilis screening because of their economy and availability. They usually become reactive within ten days after full incubation of syphilis. Since the minimum incubation period is ten days and the maximum is 90 days, syphilis cannot be ruled out by blood test short of 100 days. However, in a symptomatic patient, a nonreactive test after a symptom duration of four weeks should rule out syphilis.
