Tuberculosis Bacteria Gene Detection Test

Louisiana rates for HCPCS 87556

This laboratory test uses a gene-based amplification technique to detect the bacteria that cause tuberculosis directly in a patient sample, such as sputum coughed up from the lungs. Amplifying the genetic material makes the test more sensitive than older methods, allowing detection even when only a small amount of bacteria is present. It helps confirm a tuberculosis infection more quickly than waiting for a culture to grow.
