Antibiotic Susceptibility Testing, Disk Method

Maryland rates for HCPCS 87184

This laboratory test determines which antibiotics are likely to be effective against bacteria that have already been identified in a sample. Small paper disks, each containing a different antibiotic, are placed on a plate of growing bacteria, and the lab measures how well the bacteria's growth is stopped around each disk. Results help guide the choice of antibiotic for treating an infection.
