Brief Answer:
Possibility of biological false positive, unlikely be due to Syphilis

Detailed Answer:
Hi,
Welcome back.
RPR test positive and specific test negative means it is a case of biological false positive.
That is nonspecific test may show reactive in conditions other than Syphilis also.
Consult your doctor and rule out the possible causes for false positive result.
