Rapid Strep Test
Is it common to test positive for strep a on rapid strep and a month later test positive for strep c on throat culture?
Not unusual: Group C strep is frequently found on throat culture and is part of the normal flora that reside in the throat. As such, it's role as the causative agent in any given case of pharyngitis is often uncertain. There is no evidence Group C strep causes Acute Rheumatic Fever. *If it is cultured in an asymptomatic individual there is no necessity to treat it unless it's suspected as the cause. ...Read more

I tested positive/treated for strep 5x (rsat), little/no symptoms. Last test was positive, culture was negative. What causes false positive results?
Latent infection?: Some people have recurrent MRSA (multiply-resistant strep aureus) infections that are treated successfully and recur. There is a possibility that they (or you) could be harboring strep in your nose. The sinuses don't have great blood flow, and so may potentially "hide" bacteria. This could explain your odd results. Put bactroban (mupirocin) up your nose daily as a preventive measure, and see what happens. ...Read moreSee 1 more doctor answer
Can negative test results be trusted for a prostitute with HIV antibody rapid test and HIV duo test?
Confusing question: I suppose the question is about missing a throat infection with gonorrhea or chlamydia. The positive strep test does indicate that strep is present.

The simple strep test does not look for the additional agents. ...Read more
