CPT® Code 87469

The CPT® Code 87469 refers to a laboratory test specifically designed for the detection of the infectious agent Babesia microti through the use of nucleic acid amplification techniques, which can involve either DNA or RNA. Babesia microti is a protozoan parasite that primarily infects human red blood cells, typically transmitted via the bite of an infected tick. This parasite is responsible for causing babesiosis, a disease that presents symptoms similar to malaria, including fever and hemolysis. In addition to tick bites, babesiosis can also be transmitted through infected blood transfusions, making accurate detection crucial for patient management and treatment. The test utilizes advanced molecular techniques, such as polymerase chain reaction (PCR), to amplify the genetic material of the parasite, allowing for its identification even in small quantities. The amplification process involves converting RNA to complementary DNA (cDNA) using reverse transcriptase, followed by a series of heating and cooling cycles that facilitate the replication of the target DNA sequence. This method not only enhances the sensitivity of the test but also enables real-time monitoring of the amplification process through fluorescent or chemiluminescent probes, providing quantitative data on the presence of Babesia microti in the sample. The results generated from this test are critical for diagnosing babesiosis and guiding appropriate clinical interventions.
