About this study
Official title: Evaluation of a Diagnostic Device, CL Detect Rapid Test, for the Diagnosis of Cutaneous Leishmaniasis in Tunisia
The purpose of the study is to evaluate the sensitivity and specificity of CL Detect, in subjects with suspected CL in Tunisia.
Read the detailed description
Subjects were selected based on clinical appearance of the skin lesion characteristics of cutaneous leishmaniasis (CL). Study compared the CL Detect Rapid Test vs microscopic identification of Leishmania amastigotes in a stained lesion sample. Two diagnostic samples were collected from the subjects lesion in the following order: 1) obtained with a dental broach for use with the CL Detect Rapid Test and 2) a second sample was obtained by scraping for use in the microscopic identification of amastigotes. Samples were analyzed by microscopy and CL Detect Repaid Test by different operators who evaluated each sample independently blinded to the other assay result.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
