CPT® Code 87535

Infectious agent detection by nucleic acid (DNA or RNA); HIV-1, amplified probe technique, includes reverse transcription when performed

The CPT® Code 87535 refers to the detection of the infectious agent HIV-1 through nucleic acid techniques, specifically utilizing an amplified probe technique. This method includes reverse transcription when performed, which is essential for converting RNA into DNA, allowing for the detection of the HIV-1 virus. The procedure is critical in identifying the presence of HIV-1, a virus that significantly impacts the immune system by targeting and destroying CD4 T-cells, which are vital for the body's defense against infections. HIV-1 is one of the two main serotypes of the Human Immunodeficiency Virus, the other being HIV-2. The transmission of HIV-1 can occur through various means, including sexual contact, sharing of needles, unscreened blood transfusions, and from mother to child during childbirth or breastfeeding. The identification of HIV-1 is crucial for timely intervention and management of the infection, as it can lead to Acquired Immunodeficiency Syndrome (AIDS) if left untreated. The testing process involves obtaining a blood sample, which is then subjected to amplification techniques to ensure that even low levels of the virus can be detected. This is particularly important as direct probe methods may not be sensitive enough for samples with minimal viral presence. The amplified probe technique enhances the likelihood of accurate detection, thereby facilitating appropriate clinical responses and treatment strategies.
