  • * The study evaluated the effectiveness of polymerase chain reaction (PCR) tests on skin lesion samples (PCR-L) and blood samples (PCR-B) and compared their accuracy to traditional methods, like direct search and skin tests, in a sample of 276 suspected CL patients.
  • * Results showed that both PCR methods had higher positivity rates than conventional tests, indicating PCR-L is beneficial for chronic lesions and reinfections, while PCR-B is useful for cases with negative conventional tests or without visible lesions.
