Limitations

Reliable results are dependent on adequate specimen collection. Results should be interpreted in conjunction with other clinical data available to the clinician. A negative result does not preclude a possible infection because results are dependent on adequate specimen collection. Test results may be affected by improper specimen collection, technical error, specimen mix-up, or target levels below the assay limit of detection.

Reference Range

Note: A negative result does not completely rule out infection with T. vaginalis.
