Environmental Contamination by Chlamydia Trachomatis RNA Can Cause False-Positive Test Results in Clinical Samples.

ABSTRACT:An investigation of unexpected positive test results for Chlamydia trachomatis at a women's health clinic in Sweden revealed that samples were contaminated by RNA in the clinic. The risk for RNA contamination at a clinic has been postulated previously. We are, however, not aware that this has actually been demonstrated in practice.
