A recent Science Daily article discussed a study that found blood tests for syphilis diagnosis produce false negatives 20-30 percent of the time.
The study also found most health professionals don't have access to more reliable tests methods using fluorescent antibody testing or darkfield microscopy.
A CDC professional noted a need for a point-of-care syphilis test.
What is syphilis testing like in your lab? Do you have access to these testing methods?
