CPT® Code 87536

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

The CPT® Code 87536 refers to the detection of the infectious agent HIV-1 through nucleic acid techniques, specifically focusing on quantification. This procedure involves the measurement of HIV-1 viral load in a patient's sample, which is crucial for monitoring the progression of the infection and the effectiveness of treatment. The process includes reverse transcription, which is a method used to convert RNA into DNA, allowing for the amplification and subsequent quantification of the viral genetic material. HIV-1 is a type of human immunodeficiency virus that primarily targets the immune system, leading to a gradual decline in the number of CD4 T-cells, which are essential for immune function. The presence of HIV-1 can lead to acquired immunodeficiency syndrome (AIDS) if not managed properly. The testing for HIV-1 is vital for individuals who may have been exposed to the virus through various means, including sexual contact, sharing of needles, or from mother to child during childbirth or breastfeeding. The procedure is performed on a blood sample, where the nucleic acids are extracted and analyzed to determine the viral load, providing essential information for treatment decisions and patient management.
