CPT® Code 87197

The CPT® Code 87197 refers to the Serum Bactericidal Titer, commonly known as the Schlichter test. This diagnostic procedure is utilized to evaluate the effectiveness of antibiotics present in the blood serum against specific bacterial infections. The test measures the ability of the serum to kill bacteria, providing critical information about the potency of the antibiotics being administered to a patient. By determining the bactericidal activity of the serum, healthcare providers can make informed decisions regarding antibiotic therapy, ensuring that the chosen treatment is effective in combating the identified bacterial pathogens. This test is particularly important in cases of severe infections where antibiotic resistance may be a concern, allowing for tailored treatment plans that enhance patient outcomes.
