Neuropathy Of Leprosy

Question: I have a question about neuropathy and leprosy? What is a negative reaction and why would the negative skin test exclude leprosy?I dont get the following statement. "Lepromin test is an intradermal test with autoclaved Mycobacterium leprae antigen. It is a guide to the cell- mediated immunity of the patient against leprosy. It is not useful in confirming a diagnosis of leprosy, but a negative test can be useful to exclude leprosy in patients with peripheral neuropathy." So as an example you have a patient who has medically confirmed neuropathy you give them the Lepromin test. It is negative that would rule out leprosy is that correct? as a cause of the neuropathy? So it would be pretty sure but not 100 percent positive? Is that it? Like 95 percent say for example

Answer: what its saying is that its not the best test in confirming the diagnosis of leprosy, but a negitive test can be useful to exclude not eliminate the possibility of patients with the peripheral neuropathy. so lets say the patient is confirmed with neuropathy the negitive test would not truly emliminate the fact that it could be leporcy but it can rule it out. i would at a later time probably re test just to be sure. meanwhile find out other root causes for the neuropathy. yes, i would say 95% chance its something else that is causing the problem.
