CPT® Code 87510

The CPT® Code 87510 refers to the detection of the infectious agent Gardnerella vaginalis through nucleic acid techniques, specifically utilizing a direct probe method. This procedure is essential for identifying the presence of Gardnerella vaginalis, a bacterium commonly associated with bacterial vaginosis, which affects the female genital tract. The direct probe technique involves the extraction and analysis of nucleic acids, either DNA or RNA, from a sample obtained via a vaginal swab. This method is particularly valuable in clinical settings as it allows for rapid testing, which can often be performed in a physician's office using specialized test kits. The process begins with the collection of a vaginal swab, which is then treated with a lysate to break down cells and release the nucleic acids. The lysate is introduced into a sample well, where it undergoes a series of robotic incubations and washes to ensure that only the target nucleic acids are captured and analyzed. The specificity of the test is enhanced by the use of a Gardnerella-specific probe that binds to the target DNA sequence, facilitating the detection of the organism. A color change in the test indicates the presence of Gardnerella vaginalis, providing a clear and immediate result for the clinician. This procedure is part of a broader category of nucleic acid tests, which may also include amplified probe techniques and quantification methods for more comprehensive analysis of the infection.
