Outcome Measures

Primary Outcomes (6)

  • True Positive

    Positive by both the CL Detect™ Rapid Test and microscopy of an index lesion smear for amastigotes.

    within 1 hour after samples are taken

  • False Positive

    Positive by the CL Detect™ Rapid Test but negative for Microscopy

    within 1 hour after samples are taken

  • True Negative

    Negative by both the CL Detect™ Rapid Test device and Microscopy

    within 1 hour after samples are taken

  • False Negative

    Negative by the CL Detect™ Rapid Test but positive for Microscopy

    within 1 hour after samples are taken

  • Specificity

    Negative Specificity was calculated as the number of true negatives divided by the sum of the number of true negatives plus the number of false positives.

    within 1 hour after samples are taken

  • False Positive Rate

    False positive rate (type 1 error, calculated as 1-specificity)

    within 1 hour after samples are taken

Study Arms (1)

You may qualify if:

  • At least 18 years of age
  • Subject is able to give written informed consent
  • Subject has a skin ulcer that satisfies the following criteria for an index lesion:
  • less than 4 months in age
  • primarily ulcerative, not purely verrucous or nodular, and does not have clear clinical evidence of cellulitis
